[14:04:27] *** ahigerd has joined #zipit
[14:04:28] <ahigerd> So
[14:04:33] <ahigerd> I've pulled out my old Z2 again
[14:07:17] <ahigerd> And I realized I'm still on an ANCIENT rootfs
[14:07:26] <ahigerd> So... what's new around here in the last eight months?
[14:08:51] *** Nimare2 has quit IRC
[14:08:58] *** Bh420 has quit IRC
[14:10:55] <LT[LC]> the lack of activity pretty much answers that one
[14:11:11] <ahigerd> Well, I haven't been in here much so I don't know if there's a lack of activity or not :P
[14:12:42] <Marex> ahigerd: Z2 is supported by mainline linux kernel now
[14:12:51] <ahigerd> That's good to know :)
[14:12:58] *** Bh420 has joined #zipit
[14:12:58] *** Bh420 has joined #zipit
[14:13:10] <Marex> ahigerd: you need mainline uboot too
[14:13:42] <Marex> and you control the loader through a script on the MMC card
[14:13:44] *** Nimare2 has joined #zipit
[14:14:07] <Marex> (and I need a rootfs for this setup)
[14:14:57] <ahigerd> Hmm
[14:15:09] <Marex> rkdavis: is the rule for rootfs card layout available somewhere already ?
[14:18:19] *** Nimare2 has quit IRC
[14:21:08] <rkdavis> Marex: nope, basically eeveryone who has released a rootfs has used their own partition layout -- the most common seems to be an ext2 partition, a swap partittion and a fat partition although some have the fat part in the right place, some have it in the wrongplace
[14:22:06] <Marex> rkdavis: then they can release a new version, can't they
[14:22:31] <rkdavis> Marex: i thought we'd decided on a 100meg vfat partition for uImage and other stuff that might need to be written from windows), then a ext2/3 partition of variable size and optionally a swap partition in other words the rootfs will ALWAYS be mmcblk0p2
[14:23:22] <rkdavis> Marex: yes as you are the u-boot script guy it's basically up to you to /enforce/ the partition layout if peeople want to be able to use u-boot without having to make a script themselves
[14:23:30] *** Nimare2 has joined #zipit
[14:24:11] <Marex> rkdavis: first partition has to be vfat, the size doesn't matter
[14:24:30] <Marex> (if you want vfat there, then make it the first partition)
[14:25:01] <rkdavis> yup
[14:25:04] <Marex> rkdavis: I don't care if it's 16 or 100 megs ... enough to fit kernel (4 megs max anyway) + script (a few kb)
[14:25:15] <Marex> rkdavis: and mount it to /boot
[14:25:40] <rkdavis> i like 100meg though it's big enough for anything that needs to fit there but not too big
[14:25:46] <Marex> shuffling the partition layout shouldn't be a big deal
[14:26:08] <Marex> rkdavis: size > 16Mb ... that seems fine
[14:26:19] <rkdavis> ok
[14:26:37] <Marex> rkdavis: so MMC: [[ >16Mb VFAT ][ Anything ]]
[14:26:48] <Marex> rkdavis: make it an iron rule
[14:27:21] <rkdavis> ok
[14:27:23] *** goobers has quit IRC
[14:27:44] *** Nimare2 has quit IRC
[14:28:00] <rkdavis> 16 should be big enough for a couple of kernels, the wifi firmware and maybe the odd file so thats good
[14:29:16] <Marex> rkdavis: right ... maybe we should make it 8 megs
[14:29:21] <Marex> people can upscale it anyway
[14:29:45] <Marex> rkdavis: ah ... let's leave it to 16 ... noone will miss that space
[14:30:14] <Marex> fixup ... MMC: [[ >= 16Mb VFAT ][ Anything ]]
[14:30:56] <Marex> mmcblk0p1 MUST BE MOUNTED TO /boot
[14:31:06] <Marex> these two above are important ... ^
[14:31:09] <rkdavis> mompls
[14:33:10] *** Nimare2 has joined #zipit
[14:34:23] <Marex> rkdavis: I'd like to hear comments from rootfs people
[14:34:52] <rkdavis> Marex: well good luck finding any
[14:35:03] <rkdavis> :) the only one currently around is mozzwald
[14:35:13] <rkdavis> aliosa27 pops up occasionaly
[14:35:26] <rkdavis> jagsph is gone and the sidetrack guy is never been in here
[14:35:29] <Marex> rkdavis: who's rootfs's are used ?
[14:36:04] <Marex> mozzwald: are you fine with the layout ?
[14:37:16] <rkdavis> marex aliosa27's debian but that's nearly 10 months old, rootnexus last updated around november and sidetrack around jan or feb
[14:38:16] *** Nimare2 has quit IRC
[14:38:50] <ahigerd> I think I'm still using the original x-mouse-audio OE rootfs XD
[14:39:27] <ahigerd> And I've only got a 128MB MiniSD card right now >.>;
[14:39:29] <rkdavis> Marex: i can't see any problem with that layout -- anyone who has the fat partittion at the front of the sd card already has it
[14:39:59] <Marex> then we need a OE rootfs
[14:40:05] <Marex> debian has very poor performance
[14:40:48] <rkdavis> yup oe has been left as gpsfan doesn't really like it and it stagnated a bit as it couldn't build blob based rootfs since around december
[14:41:07] <rkdavis> and everyone was using debian anyway other than gpsfan
[14:41:27] <Marex> yes, but debian is really slow ... and it's compiler for armv4, not armv5 so the optimization sucks
[14:41:35] <rkdavis> and sweetlilmre is the only one with commit privs other than aliosa27
[14:41:37] <Marex> so you can either recompile debian, or use OE
[14:41:44] <Marex> and OE is imho the better choice
[14:42:02] <Marex> rkdavis: commit privs ... where ?
[14:42:21] <rkdavis> yup the problem with oe that gpsfan feels (and i sort of agree with) is that it's used for both kernel and rootfs building and hard to seperate out
[14:42:44] <rkdavis> personally hee thinks and i agree the kernel shoudl be done outside of oe and oe shoudl just be fore the rootfs
[14:42:51] <Marex> rkdavis: so what ... I build everything with OE for my boards
[14:42:58] <Marex> why ?
[14:43:04] <rkdavis> Marex: openzipit.sourceforge.net -- where the zipit oe branch is
[14:43:13] *** Nimare2 has joined #zipit
[14:43:26] <Marex> rkdavis: why don't you push it mainline ?
[14:43:45] <Marex> rkdavis: also, now that Z2 is in mainline, it should be only a matter of adding kernel config to OE
[14:44:13] <rkdavis> Marex: because as i've told you on many occasions i'm userspace orintated and i din't have the accounts on openzipit -- i've left the kernel to ppl like sweetlilmree and gpsfan
[14:44:54] <Marex> rkdavis: ok ... FTTB you can just reuse the spitz config for 2.6.34
[14:44:54] <rkdavis> and oe takes a hell of a long timee to build -- over 24 hours in my vm initially
[14:45:08] <Marex> rkdavis: that'll build a fake kernel (kernel for spitz) and then you'll replace it in the rootfs
[14:45:19] <Marex> rkdavis: don't build in VM then 3-/
[14:46:00] <rkdavis> Marex: have to -- no linux boxees left at the momeent -- the ultrasparc is being used as a dev box for another client and this one has to stay as windows for the kids school work
[14:47:02] <rkdavis> i'll see if i can get the passwords to the openzipit sourceforge account from sweetlilmre though , i'll email him in a bit
[14:47:21] <Marex> rkdavis: you can get me one as well
[14:47:23] <rkdavis> i've actually been playing aroudn with buildroot for everything recently though
[14:47:30] <Marex> rkdavis: but it's stupid to keep the work out of mainline
[14:47:32] <rkdavis> it's very finicky
[14:47:36] <ahigerd> I used a Debian VM to build my OE
[14:47:40] *** Nimare2 has quit IRC
[14:47:48] <rkdavis> Marex: yes it is but as i don't have access to it i can do nothing to push it
[14:48:11] <Marex> rkdavis: OE has patchtracker ... you send patches
[14:48:19] <rkdavis> i've asked those that can push it to do it but i can't thwap them with a cold wet trout if they ignore the request
[14:48:42] <Marex> rkdavis: put the patches into the patchtracker and keep an eye on them
[14:49:08] <rkdavis> i've actually been trying to get buildroot configured again to build z2 rootfs -- it broke on the .02 release
[14:49:21] <rkdavis> something to do with the br2_board stuff
[14:49:40] <rkdavis> the buildroot rootfs would be the lightest
[14:50:26] <ahigerd> Yeah, but also the hardest to extend because BR doesn't do packages
[14:50:30] <ahigerd> (unless I'm mistaken?)
[14:50:33] <Marex> you can configure OE to build a lightweight rootfs too
[14:50:50] <Marex> ahigerd: it can do ipk, but that's old crap
[14:51:01] <Marex> opk is the way to go
[14:51:31] *** Nimare2 has joined #zipit
[14:52:13] <rkdavis> ahigerd: it sort of does but it requires a bit more effort to add new stuff but after you've done it a few times it is pretty straight forward, very similar to writing bitbake recipes
[14:52:38] *** Nimare2 has left #zipit
[14:52:39] <Marex> rkdavis: so why not stick with OE in the end ...
[14:53:51] <rkdavis> Marex: because as i've said i'm not even using anything but scratchbox, tinycc and ash atm -- not had time to do anything with my other two zipits (and buildroot does the other cpu i need to make a rootfs for too :) )
[14:54:25] <Marex> then make someone else play with OE
[14:54:33] <rkdavis> but the oe, uboot, rootfs stuff is not on my radar atm as i'm still in scripting mode for stock
[14:54:58] <rkdavis> Marex: but you are busy :) and until the lambs arrive gpsfan is playing with his bloody sheep :)
[14:55:18] <rkdavis> i don't think ahigerd is doign much at the moment though

[16:10:18] <Marex> nope
[16:11:15] <Marex> mozzwald: I'd prepare a binary if I had time ... dang
[16:12:11] <Marex> mozzwald: wait ...
[16:14:07] <Marex> mozzwald: do you have serial console ?
[16:14:18] <mozzwald> Marex: if one had a binary of it, couldn't you just dd it to the proper mtdblock?
[16:14:22] <mozzwald> Marex: yes
[16:14:35] <Marex> mozzwald: no ... it's too big
[16:15:10] <mozzwald> I mean directly from the booted zipit?
[16:17:38] <Marex> yes
[16:17:46] <Marex> I flashed one Z2 that way

[16:27:51] <Marex> mozzwald: you'll need to "make uImage when compiling kernel"
[16:27:56] <Marex> "make uImage"
[16:28:38] <Marex> it won't load the standard zImage
[16:29:18] <Marex> also, be aware that the final flash partition layout for Z2 is the following:
[16:31:17] <Marex> [0x0-0x40000 u-boot][0x40000-0x60000 env][rest ...]
[16:33:32] <Marex> mozzwald: tell me if it works
[16:33:38] *** rkdavis has joined #zipit
[16:33:54] <Marex> rkdavis: another rule :
[16:34:00] <Marex> NOR: [0x0-0x40000 u-boot][0x40000-0x60000 env][rest ...]
[16:35:23] <mozzwald> Marex: will do. I'll hafta do this in a few hours when I get home from work. You gunna be around to hold my hand? :)
[16:35:29] <rkdavis> you mean the partitioning on the zipit? -- what about your idea of the kernel and initramfs on the zipit that it defaults too if no sd card
[16:35:58] <Marex> rkdavis: that's what "rest" is for
[16:36:46] <Marex> rkdavis: maybe we can have a small SWAP there :b
[16:36:50] <rkdavis> ah ok -- so what happens is that u-boot defaults to booting that if it doesn't see a script on an sdcard -- correct?
[16:36:52] <Marex> mozzwald: depends ... it's 11pm here
[16:36:58] <Marex> nearly 11pm
[16:37:10] <Marex> rkdavis: exactly
[16:38:42] <rkdavis> Marex: ok makes sense -- so we'll also need /standard/ known kernel to install there and a small busybox based initramfs too -- base it on say .34 and teh zipits stock rootfs with the wifi firmware in it
[16:39:03] <rkdavis> just something to bootstap a shell and do wifi
[16:40:02] <Marex> rkdavis: you can prepare the initramfs with buildroot ... that's what it'd be good for
[16:40:10] <rkdavis> if we also include kexectools in the initramfs and enable it on the kernel
[16:40:26] <Marex> rkdavis: why? you can just drop uImage to the card
[16:40:38] <Marex> (or fix your own bootscript for the bootloader)
[16:40:39] <rkdavis> Marex: yup just a small light and tight one with the bare minimum
[16:40:54] <Marex> rkdavis: exactly ... maybe dropbear and wireless tools
[16:40:59] <Marex> that should fit
[16:41:09] <rkdavis> Marex: kexec is always handy to have just in case
[16:41:22] <rkdavis> say the vfat partition gets correcupt
[16:41:27] <rkdavis> corrupted even
[16:41:41] <Marex> rkdavis: then you're screwed ;-)
[16:41:47] <Marex> ok ... I see your point, that makes sense
[16:41:50] <rkdavis> not neccessarily
[16:42:03] <rkdavis> you could wget a new kernel and kexec it
[16:42:15] <Marex> you have more than 7 megs for the kernel ... enable LZMA and you'll fit there
[16:42:15] <rkdavis> but you could do it without anyway
[16:42:32] <rkdavis> use busybox fdisk, redo the partition and format and away ya go
[16:42:49] <Marex> and how do you load the kernel ?
[16:42:51] <Marex> from where ?
[16:42:54] <ahigerd> How big is kexec?
[16:43:00] <ahigerd> Is it really big enough that we're worried about it?
[16:43:01] <Marex> ahigerd: it's part of kernel
[16:43:03] <ahigerd> I know that
[16:43:10] <rkdavis> yup u-boot and a kernel would only be a meg or so and that'd leave upto 7,eeg for the rootfs in the flash
[16:43:37] <Marex> rkdavis: kernel would be more like 2 megs
[16:43:42] <rkdavis> so prbably 10meg of compressed data give or take a few
[16:43:59] <rkdavis> ok 6meg compressed then so maybe 9meg if we are lucky
[16:44:23] <rkdavis> static busybox with everything is about 1.2meg
[16:45:00] <rkdavis> wpa_supplicant and wirelesstools are about another 1.5meg
[16:45:31] <rkdavis> but that's about all we'd need that aren't available from busybox so we could add lua in as well
[16:45:45] <ahigerd> What would we do with lua...?
[16:46:06] <Marex> right ... why lua ?
[16:46:07] <rkdavis> ahigerd: it's a nice scripting/glue lang. handy sometimes
[16:46:23] <rkdavis> Marex: because ruby, python... are too heavy
[16:46:24] <ahigerd> I know what lua IS
[16:46:38] <ahigerd> I'm just wondering what it's doing on an emergency rootfs
[16:46:40] <rkdavis> runby and python will suck all the ram
[16:47:10] <rkdavis> ahigerd: i like to have it there in case i want to knock up a quick script that shell is not quite right for
[16:47:16] <rkdavis> always handy to have a scripting lang
[16:47:48] <Marex> rkdavis: you should hold to general purpose emergency rootfs
[16:48:01] <Marex> rkdavis: so beef it up with tools that might be handy (mkfs, fsck) ... not lua
[16:48:20] <rkdavis> ahigerd: in my iz2s variant i have only 3 major things other than busybox, wpa-supplicant and wirelesstool -- lua, dialog and dropbear
[16:48:34] <rkdavis> Marex: they are in busybox so why bother
[16:49:02] <rkdavis> if you have space use it -- on and i have curl too
[16:49:21] <rkdavis> s/on/oh
[16:49:50] <Marex> rkdavis: why not links then ?
[16:50:04] <ahigerd> Doesn't busybox have wget embedded?
[16:50:25] <rkdavis> Marex: because i don't do alot of browsing -- i have it in user versions of iz2s but not on my personal version
[16:50:40] <rkdavis> ahigerd: yes it does but curl is better for alot of things
[16:50:45] <ahigerd> Fair enough
[16:51:03] <rkdavis> wget isn't great at putting filees curl will get and put
[16:51:05] <Marex> rkdavis: fine, but we should prepare a general purpose rootfs ...
[16:51:18] <Marex> rkdavis: webbrowser might be much more handy
[16:51:36] <rkdavis> Marex: yup and i think links isn't something that shoudl be in a initramfs, in rootfs yes but not in the onboard flash
[16:51:54] <rkdavis> Marex: you can emulate a browser quite well with curl and lua
[16:52:17] <rkdavis> well curl and bash even but...
[16:52:45] <rkdavis> Marex: also static links is about 2 to 3 meeg at least
[16:53:11] <rkdavis> and still about 900k shared -- too large for initramfs
[16:54:16] <Marex> rkdavis: lynx then
[16:54:44] <Marex> rkdavis: just compile it without lua and see how much is left
[16:54:57] <rkdavis> Marex: lua is 200k
[16:55:12] <rkdavis> actually a bit less but i add a few extras to my version
[16:57:41] <rkdavis> just checked -- static links is over 5meg and static lynx is 2meg
[16:57:52] <Marex> rkdavis: please keep in mind we're going to release it ...
[16:57:56] <Marex> rkdavis: ok ... put lynx into it
[16:58:03] <Marex> it'll fit
[16:58:22] <rkdavis> Marex: yup it'll be tight but shoudl just squeeze in
[16:59:07] <rkdavis> but it'll be very tight -- adding up the sizes of all the thing si have hear -- and stripped it's 7meg
[16:59:56] <rkdavis> but i guess wpa_passphrase can be lived without
[17:00:14] <rkdavis> brb
[17:00:24] <rkdavis> need to check on the chicken in the oven
[17:01:17] <Marex> rkdavis: LZMA compression should do the job
[17:04:17] <Marex> rkdavis: we need also hotplug/coldplug to load the wifi firmware !

[19:46:09] <beaglebreath> If you want I've got a vga card with just the ISA part of the connector (without the extended ISA portion)
[19:46:47] <geordy> So it's a true 8-bit vga card?
[19:47:11] *** DoorToDoorGeek has joined #zipit
[19:47:16] <beaglebreath> Let me find it, and we'll see.
[19:51:18] <geordy> I bought an IBM XT the other day for the heck of it
[19:51:26] <beaglebreath> well, I found some old CGA cards...
[19:51:27] <geordy> but I don't have an ega monitor :(
[19:51:32] <geordy> or CGA
[19:51:34] <geordy> hehe
[19:52:03] <beaglebreath> here's my 287 coprocessor!
[19:52:06] <geordy> but like I was saying, most of the VGA cards will work in 8-bit mode so I hear

[19:55:32] <beaglebreath> I've got a complete PC104 computer with a VGA port. - but It'd be a science project since you'll have to burn eproms to hold your programs

[20:04:30] <beaglebreath> oh the posibilities...
[20:05:33] <beaglebreath> got win 3.11 on 3.25 disks 1 through 11
[20:05:48] <geordy> better save that or you WILL regret it

[20:16:40] <Marex> though I was never able to install it in qemu or anything :/
[20:19:46] <geordy> I had windows 1.03RT I think
[20:20:07] <geordy> it was a runtime version packed with an early version of pagemaker I think
[20:20:14] <geordy> it worked
[20:20:16] <geordy> it was weird
[20:20:32] <beaglebreath> i got really really lucky. i bought a calibration business six years ago and now have 5000 sq.ft of old electronic junk to play with.
[20:20:46] <geordy> that's pretty cool
[20:21:24] <beaglebreath> yeah, it's more stuff than I can play with in a life time.
[20:21:44] <geordy> surely not all of it is interesting
[20:21:57] <geordy> what is the oldest stuff in there?
[20:22:43] <beaglebreath> before this i was trying to build a spectrum analyzer out of an old scope and a scanner radio. now I have four hp spectrum analyzers and no time to play with them.
[20:23:59] <beaglebreath> most prized possesion is a AN/USM-339 analog oscilloscope.
[20:24:21] <geordy> I just snagged a tek 465b off CL for $100
[20:24:29] <geordy> I thought that was fair
[20:24:46] <geordy> I haven't had time to plug it in and play with it yet though :(
[20:26:01] <beaglebreath> is that a scope?
[20:26:07] <geordy> yeah
[20:26:21] <geordy> one of the most popular analog scopes ever built
[20:26:53] <beaglebreath> i have three 475's that are fubar if you need parts or knobs etc..
[20:27:28] <beaglebreath> does it have a gpib adapter?
[20:27:30] <geordy> sweet! hold onto those. I understand the knobs are hard to come by
[20:27:53] <geordy> no clue what gpib is
[20:28:03] <geordy> it come with several probes though

[22:56:52] <mozzwald> Marex: From serial, uboot says no mmc card found
[22:57:04] <Marex> mozzwald: insert the card then
[22:57:07] <rkdavis> geordy: yes gpsfan, sweetlilmre and a myriad others
[22:57:19] <geordy> alright alright so it's just MY problem
[22:57:21] <geordy> doh
[22:57:44] <Marex> geordy: the link I posted here is an uboot update package for stock Z2
[22:57:46] <mozzwald> Marex: prompt is working
[22:58:14] <Marex> mozzwald: ok, if you pop in the card and type "mmc init" ... what happens ?
[22:58:15] <geordy> rkdavis: btw, supposedly most/many 16-bit VGA cards will work in 8-bit mode if there is room for the extended connector to overhang the slot
[22:59:08] <geordy> 8-bit ISA VGA is pretty freakin' scarce but if you magically find me one, I'll send you something really cool
[22:59:51] <ahigerd> I had one at my last job
[22:59:58] <ahigerd> Er, wait, no, that was PCI, never mind
[23:00:08] <geordy> hehe I was going to say...
[23:01:06] <mozzwald> still says no mmc found
[23:02:13] <mozzwald> Marex: I also get "Wrong image format for bootm command"
[23:03:26] <Marex> yeah ... because you don't have kernel image at 0x60000 in flash
[23:03:46] <Marex> mozzwald: can you try a different card ?
[23:03:56] <Marex> mozzwald: or ... what card do you have ?
[23:05:25] <mozzwald> MArex: just did. that seems to be the problem
[23:05:27] *** goobers has joined #zipit
[23:06:14] <Marex> mozzwald: your card isn't detected ?
[23:06:22] <Marex> mozzwald: don't joke with me ... is isn't ?!
[23:07:00] <mozzwald> Marex: I had a 4gb card and it would not detect at all. just put in a 1gb and it found it fine
[23:08:53] <Marex> 4GB SDHC ?
[23:09:00] <Marex> could it be U-Boot doesn't support that ?
[23:09:03] <Marex> hmmmm ...
[23:09:18] <Marex> I'll try SDHC when I have time
[23:23:48] <Marex> mozzwald: check your email
[23:27:39] *** DoorToDoorGeek has left #zipit
[23:29:24] <Marex> dTal: you had those wifi issues, right ?
[23:30:09] <Marex> dTal: try firmware from here and let me know how it works http://git.infradead.org/users/dwmw2/linux-firmware.git?a=tree;f=libertas ... I'll forward it
[23:31:27] *** mozzwald has quit IRC
[23:32:59] *** ahigerd has left #zipit
[23:41:24] <geordy> so is uboot totally stable now?
[23:42:56] <ssieb> geordy: I checked through my collection of ancient cards and the only 8-bit video cards are cga/ega
[23:44:06] <Marex> geordy: suspend-to-mem seems to be buggered
[23:44:15] <Marex> geordy: standby works fine though
[23:47:16] <rkdavis> geordy: ok not in those bags but i have some boxes in the kids room i'll look in therein the morning -- havee a mice pci video card with tv out and what looks to be a tuner daughter board though, bloody huge but cool looking :) and what looks to be one of my collection of isa floppy controllers wither external floppy connector
