[21:22:09] <T0mW> GPSFan: ping
[21:23:33] <GPSFan> T0mW: hey, how's it goin...
[21:23:44] <T0mW> GPSFan: you'll be interested in this...
[21:23:54] <GPSFan> k
[21:24:18] <T0mW> Same OE build: AMD X2 4800 == 202 minutes, Intel Q6600 (Quad) == 90 minutes
[21:24:37] <T0mW> less than half the time
[21:24:49] <GPSFan> T0mW: so you got your MegaBox running, I see...
[21:25:47] <T0mW> heh, yeah. It came Friday, I yanked the AMD X2 6400 out and shoved the Intel Quad in.
[21:25:51] <GPSFan> how much ram in each?
[21:26:12] <T0mW> AMD X2 4800 == 4Gig, Intel Q6600 == 8gig
[21:26:43] <T0mW> GPSFan: Same test, using AMD X2 6400 w/8gig ram == 120minutes
[21:26:55] <GPSFan> wow that's a lot...
[21:26:56] <T0mW> no
[21:26:57] <T0mW> no
[21:27:05] <GPSFan> no no no
[21:27:06] <T0mW> 2hrs 15mins...
[21:27:12] <T0mW> 135 mins
[21:27:42] <T0mW> I was thinking two hours, but it was actually 2hrs 15mins for that build
[21:28:21] <T0mW> Interesting thing is that a 56min build on the AMD X2 6400 took 50min on the Q6600
[21:28:31] <GPSFan> so the ram had quite an effect, I'd compar the 135min to the 90min. still that sounds like a nice box, it just a headless server or a desktop with graphics?
[21:28:37] <T0mW> seems most of the parallel threading happens *after* you build glibc :(
[21:29:16] <T0mW> GPSFan: desktop, no change between init 3 and init 5, same times (within a minute).
[21:29:38] <T0mW> Interesting that X didn't affect things
[21:29:41] <GPSFan> things have been quiet here for a while.
[21:29:47] <T0mW> :D
[21:29:53] <T0mW> I like it when life goes that way
[21:30:40] <T0mW> GPSFan: I've been very busy since I got back
[21:31:10] <T0mW> I started looking at houses and talking tenatively with mortgage company
[21:31:26] <GPSFan> I got a startup script running that allowws the Zipit2 app to start up and let me ssh in. I'm trying to figure out the led's, bat charging, and backlight stuff.
[21:32:13] <T0mW> GPSFan: you have any data on the pxa270 internals ? Doesn't seem to be a datasheet publically available anywheres.
[21:32:15] <GPSFan> oooh house... mortgage... debt.....
[21:32:55] <T0mW> GPSFan: nail bookcases to walls, cut holes for air conditioner, the bad things your landlord freaks over.
[21:32:58] <GPSFan> yeah there is a usermanual and datasheet from intel. I forget where I got them but it only took a bit of googling.
[21:33:19] <T0mW> All I found was a wimpy cutsheet
[21:33:28] <GPSFan> I can dcc them to you if you want.
[21:33:44] <T0mW> GPSFan: I have no debt, that is un-American!
[21:33:54] <GPSFan> indeed... me too...
[21:34:05] <T0mW> GPSFan: naw, just good to know that you have it if needed.
[21:34:39] <T0mW> mortgage payments would be cheaper than the taxes
[21:34:57] <GPSFan> pxa270_ds.pdf & pxa270_um.pdf
[21:35:00] <T0mW> well, not quite, but you know what I mean.
[21:36:05] <GPSFan> 2M for the ds & 11M for the um.
[21:37:23] <T0mW> just pulled them off of phytec
[21:38:03] <GPSFan> ok, there is a lot of stuff in that chip, including a camera interface that zipit brought out the rear connector.
[21:38:46] <T0mW> I've been focusing on getting a decent build machine together for OE. Now that I have that, I can play a little. Right after I finish the two schematics for this one customer. :/
[21:39:12] <T0mW> GPSFan: ah, so you been wigglings pins again?
[21:39:49] <Backer> Hello
[21:39:55] * T0mW hides
[21:40:19] <Backer> ;o)
[21:40:20] <T0mW> Backer: wassup?
[21:40:21] <GPSFan> ah, has roxfan made any progress on the gpios? yeah I use devmem2 and have mapped out the GPIOs and most of their initial states/
[21:40:27] <Backer> not too much
[21:40:35] <Backer> got my z2 a few days ago
[21:40:40] <T0mW> GPSFan: I have heard nothing from him
[21:40:51] <GPSFan> hrumph
[21:40:59] <T0mW> shrug
[21:41:23] <T0mW> sometimes you will have this. He is prolly swamped with other stuff, as we all tend to get.
[21:41:37] <Backer> I noticed the mic in lines on that back port as well...
[21:41:41] <T0mW> Backer: so, what you gonna do with it?
[21:41:45] <GPSFan> yeah, that's more common than having lots of free time.
[21:42:11] <T0mW> GPSFan: you have a wife, so, she takes the free stuff
[21:42:13] <T0mW> heh
[21:42:15] <T0mW> ;)
[21:42:28] <Backer> well I figure if I can get vice running on it at some point that would be nice ;o)
[21:42:31] <GPSFan> T0mW: no, the farm takes most of the free stuff.
[21:42:37] <T0mW> HA!
[21:42:47] <T0mW> GPSFan: always fences to mend
[21:43:01] * T0mW was farm boy
[21:43:46] <T0mW> Backer: yeah, we are basically still doping things out inside the unit.
[21:43:53] <Backer> what are you two trying to do with it?
[21:44:00] <GPSFan> T0mW: there is always something.
[21:44:22] <Backer> indeed... I was just happy to see there was at least some kind of audio input
[21:44:22] <T0mW> I would like to get a desktop (X server) running on it and get mouse emulation working with the keyboard
[21:45:17] <Backer> so far it is just a raw framebuffer?
[21:45:23] <T0mW> I think I had X running on it before I got sidetracked 3..4 weeks ago. Too much has gone down since then
[21:45:40] <Backer> nice!
[21:45:45] <T0mW> definately will only ever have a framebuffer. Most ARM SOCs are that way
[21:46:13] <T0mW> no accelerated graphic chipsets in these tiny things.
[21:46:17] <Backer> any reports on audio output?
[21:46:30] <T0mW> that should be working by now
[21:47:04] <Backer> I have yet to get the OE build set up. I'm hoping for the weekend...
[21:47:17] <GPSFan> T0mW: the audio needs a mixer to talk to the WM87?? DAC, there is nothing in the current audio driver code to do that,
[21:47:25] <T0mW> there must be some irc logs around someplace for this channel. I haven't been here in about 3 weeks, they were doing something with the audio back then to get it running.
[21:47:30] <T0mW> ah
[21:48:00] <GPSFan> T0mW: I had to do the same for the Z1. similar config of ARm & external dac.
[21:48:06] <T0mW> nod
[21:48:38] <T0mW> I'm going to focus on getting angstrom working on the Z2, then maybe that will generate more interest, more help
[21:49:11] <T0mW> at least, that will fit into my commercial projects: angstrom + X
[21:49:26] <T0mW> GPSFan: you ever mess with Xscale?
[21:49:31] <T0mW> iop320?
[21:49:37] <T0mW> iop13xx ?
[21:49:59] <T0mW> or debian arm ?
[21:50:31] <GPSFan> T0mW: a bit with the NSLU2 and a Gateworks 2348-4. they are both intel xscale.
[21:50:41] <T0mW> I have a commercial project with an IOP348 (dual ARM cores + 8 SATA ports + Gigabit LAN) to run Debian ARM v4
[21:50:43] <GPSFan> not marvel PXA
[21:51:02] <T0mW> this is definately an Intel monstrosity: 1200MHz
[21:51:09] <GPSFan> yikes..
[21:51:16] <T0mW> prolly only dual 600MHz cores.
[21:51:24] <T0mW> arm5tel
[21:51:52] <T0mW> never saw one until Thursday, interesting animal
[21:51:55] <GPSFan> I'm sure they aren't clocking it at 1200, 600 maybe, ( my 2348 clocks at 533)
[21:52:11] <GPSFan> pricey I bet.
[21:52:24] <T0mW> yes, they say 1200, but that is two ARM processors inside one chip, so prolly two 600MHz cores.
[21:52:41] <T0mW> they are using it for an ISCSI NAS
[21:52:42] <GPSFan> I'll believe that.
[21:52:58] <GPSFan> should be a good app for it/
[21:53:10] <T0mW> I guess one core to run the SATA drives, the other to feed the Gigabit
[21:53:24] <T0mW> 256Meg of RAM
[21:53:40] <T0mW> IIRC, DDR or DDR2 RAM
[21:54:03] <T0mW> I hope he lets me take it home to play with. :)
[21:54:11] <GPSFan> T0mW: do you have one of those boards? are they available?
[21:54:37] <T0mW> They are some kind of dev board, this one is branded: "Silver Lake"
[21:54:48] <T0mW> Intel makes the dev board
[21:55:41] <T0mW> Not sure who the end-customer is, I'm working with a consultant (windows guy, ex-VAX programmer)
[21:56:35] <GPSFan> interesting,
[21:56:54] <GPSFan> mmmmm VAXEN...
[21:58:14] <T0mW> ;)
[21:58:37] * GPSFan listens for the sound of thundering vaxen hooves.
[21:59:21] *** FireEgl has quit IRC
[22:02:15] <GPSFan> T0mW: btw the 2348 was an IXP425 @533Mhz. I did have debian armeb running on it. It was a prototype for a multi radio wireless access point/backhaul box.
[22:02:23] <T0mW> well, I will see how this goes. He is supposed to talk with the end-customer as to their requirements. Odd situation, but, I always seem to get caught up in those things. Original developer bailed on the project, didn't collect his fee, and didn't complete the work. They have a working system, but no way to replicate it but from the binary images.
[22:03:05] <GPSFan> not opensource based? or was it?
[22:03:30] <T0mW> I found git patches for the intel iop kernel up on sourceforge, just will have to try to compile it and test it out.
[22:03:46] <T0mW> recent kernel stuff too, 2.6.24
[22:04:06] <T0mW> lots of strange stuff on sourceforge
[22:04:23] <T0mW> OSS vomit
[22:04:32] <GPSFan> the IOP series xscale are differnet animals than the IXP devices.
[22:04:44] <T0mW> yeah, integrate SOCs
[22:04:49] <T0mW> yeah, integrated SOCs
[22:05:09] <T0mW> one-chip-wonders
[22:05:12] <T0mW> heh
[22:05:25] <GPSFan> does it have a pci bus for external peripherials?
[22:05:29] <T0mW> yes
[22:05:34] <T0mW> and pci-e
[22:05:52] <GPSFan> what about co-processors NXP & crypto?
[22:05:57] <T0mW> DDR2 bus to 4Gig
[22:06:05] <T0mW> no co-pro
[22:06:37] <GPSFan> ok, does it have the io bw to support GigE
[22:07:09] <T0mW> yes, 6.4gigabits internal bus
[22:07:33] <GPSFan> internal GigE controller of via the pci-e
[22:07:34] <T0mW> 128bit 400MHz internal bus
[22:08:09] * GPSFan should look up the chip.
[22:08:14] <T0mW> not sure, I have yet to see a schematic on this board. There is a SATA support chip on the board, I think it is a driver though, not a subsystem.
[22:08:24] <T0mW> like a PHY
[22:08:48] <T0mW> interesting as all hell though!
[22:08:58] <GPSFan> indeed.
[22:09:00] <T0mW> 667..1200MHz core speed
[22:09:15] <T0mW> that would rock
[22:09:45] <T0mW> give me your poor, tired hardware, monster SQL dataset...
[22:10:06] <GPSFan> and if it has the io bw to handle multiple SATA and GigE that would make a mighty fine NAS
[22:10:26] <T0mW> Interesting thing is that you don't see any dev boards offered on the Intel site for those processors
[22:11:11] <T0mW> almost as if Intel is not interested in the "small stuff" and only the big players.
[22:11:17] <GPSFan> they have them, it's up to your Intel rep to qualify you as a customer, then you can get some really neat stuff.
[22:11:30] <T0mW> I guess that is why Marvell is doing the IOPs now?
[22:11:46] <T0mW> doh
[22:11:50] <GPSFan> sort of like Ti & OMAP
[22:11:50] <T0mW> I meant IXP
[22:11:55] <T0mW> right
[22:12:22] <GPSFan> I thought that Intel kept the IXP & IOP and sold of the PXA stuff to Marvell.
[22:12:33] <T0mW> wonder how that will play out, intel made a lot of money on the 8051 selling in small lots.
[22:13:08] <T0mW> was that it? just the PXA? I thought they bailed on all Xscale production
[22:13:27] <GPSFan> no, they kept some I thought it was IOP & IXP.
[22:13:33] <T0mW> al
[22:13:36] <T0mW> bah
[22:13:37] <T0mW> ah
[22:13:41] <GPSFan> arggg
[22:13:45] <T0mW> hehheh
[22:14:07] <GPSFan> those swarthy dogs..
[22:14:13] <T0mW> you need a scorecard to follow this stuff anymore
[22:15:23] <T0mW> All I know is that I have this wimpy 200MHz Samsung core to work with. I've been wondering if we were to goto a 300/400MHz IXP core and run the SPI via the bit-bang that would all we would need?
[22:16:12] <GPSFan> the Samsung is probably more power efficient, but that may not be important in your app.
[22:16:13] <T0mW> I have no need for highspeed hardware SPI, I am now thinking that an I/O Port SPI might be better as I could use a faster core for the main app.
[22:16:28] <T0mW> power efficiency is critical
[22:16:56] <T0mW> they freaked when I told them that the Samsung would prolly be sucking up 3watts or so.
[22:17:09] <GPSFan> that a 2410?
[22:17:13] <T0mW> yes
[22:17:25] <T0mW> 2410 + the RAM
[22:17:40] <GPSFan> 3 watts is kind of a lot, the Hammer is a lot less IIRC
[22:18:27] <GPSFan> that's 1A at 3.3v. how much ram does it have?
[22:18:50] <T0mW> that was for the whole CPU board, bunch of 16bit IO chips, an ethernet. I didn't tell them what the two USB ports would be doing... hehh
[22:19:08] <T0mW> IIRC, it is 128Meg
[22:19:19] <T0mW> ethernet sucks 250ma
[22:19:38] <GPSFan> ok, the ethernet & USB and all that ram will surely suck a bit...
[22:19:59] <T0mW> now they want dual 10/100 ethernets on the board. They are starting to get power-drunk
[22:20:08] <GPSFan> feature creep.
[22:20:25] <T0mW> yeah, well the old CPU board ran about 200ma @ 5v
[22:20:57] <T0mW> that was an 80C188 w/512K RAM, not much else but some CMOS glue
[22:21:18] <GPSFan> you might look at an IXP425, it has dual 10/100 ethernets on board, no USB2 though. but that can go on the pci
[22:21:26] <T0mW> hmm
[22:22:00] <T0mW> all of this is to go onto a 4" X 10" board
[22:23:06] <GPSFan> this is the ixp board I have, it works very well and draws less than their figures.
[22:23:08] <GPSFan> http://shop.gateworks.com/index.php?act=viewProd&productId=2
[22:23:13] <T0mW> we'll see how this spins out with the 2410
[22:24:11] <T0mW> hey, wait another month and XXXX will be out. This stuff is changing too fast anymore, you cannot keep up. What you design today, release 6 months from now, will be out of date by then.
[22:24:48] <T0mW> Somewhere you have to say "stop" and go with it.
[22:25:11] <GPSFan> 2440 =>2550 =>2660 where will it ever end?
[22:26:41] <T0mW> two years ago I had a contract to design a replacement for a board I did 15years ago. The first design used two ARM7TDMI processors, the second design proto revised that almost a year later with a single ARM7TDMI that just came out, then, I get this S3C2410 module for $85 from China...
[22:27:22] <T0mW> I have that design sitting here as a test bed. I let them see it but they don't understand what it is.
[22:27:45] <T0mW> Linux in it now instead of the proprietary o/s it took me a year to write.
[22:28:23] <T0mW> That o/s in this latest rendition is from OE
[22:29:41] <T0mW> So, for $60 more in parts, you slash your engineering costs. They are a low-volume OEM, less than 200 units per year. They don't see the engineering savings, only the additional per unit cost.
[22:29:44] <T0mW> heh
[22:30:27] * T0mW looks to see if S3C2440 is on a SODIMM yet.
[22:31:47] <T0mW> LOL
[22:31:49] <T0mW> it is
[22:31:57] <GPSFan> it's amazing how much technology you can get for a $ today, in another couple of years that stuff will be overproced and obsolete. yet here I am paying $4/10/gal for diesel. ;>(
[22:32:03] <T0mW> 400MHz on an a 200pin SODIMM
[22:32:16] <GPSFan> url?
[22:32:41] <T0mW> http://mdstec.com/english/solutions/images/SUMA_TETRA_spec.gif
[22:32:58] <T0mW> 67x31 MM
[22:33:02] <T0mW> 67x31mm
[22:33:18] <T0mW> looks to be a standard sodimm footprint
[22:33:49] <T0mW> and, it *only* has 512Meg of RAM
[22:36:56] <GPSFan> that sight is wierd, it doesn't like firefox, not much more info than that picture.
[22:37:45] <T0mW> Firefox here works ok
[22:38:09] <T0mW> but I have javascript + java disabled
[22:38:33] <GPSFan> maybe just me. any doc's other than what's on the picture?
[22:39:10] <T0mW> http://mdstec.com/english/solutions/evaluation_board_suma_tetra.html
[22:39:46] <T0mW> it looks like and EVB kit, not a production offering of the SODIMM.
[22:41:43] <GPSFan> looks like they want to sell the sodimms, the main board is just for eval.
[22:44:33] <GPSFan> I wonder if that is a typo "512Mbit" mobile SDRAM
[22:46:51] <T0mW> I just sent a inquiry to them about that 2440 SODIMM
[22:47:37] <T0mW> I would rather use the 400MHz processor over the 200MHz one, better to have too much processing power.
[22:48:16] <GPSFan> let me know what you find out, pricing and all, that looks like a nice board (sodimm)
[22:48:31] <T0mW> GPSFan: could be, but, you know that you can purchase 2Gig DDR2 modules now. 8 chips on the DIMM, so it may be that is not a typo.
[22:49:45] <GPSFan> they have all their memory figures in Mbit. I bet they mean Mbyte. 32Mbits of flash is somewhat worthless
[22:50:01] <T0mW> ah, you are correct. 512Mbit would be, what, 64Mbyte?
[22:51:51] <GPSFan> well maybe not useless, enough for a bootloader.
[22:52:10] <T0mW> We'll have to see what their pricing model is
[22:52:16] <GPSFan> indeed.
[22:52:59] <T0mW> sub $100 / 100lot might be worth it. I am only running two LANs, an SPI array, MMC card with mysql.
[22:53:08] <T0mW> no video
[22:54:01] <T0mW> realtime response burden is on the ARM7TDMIs at the other end of the SPI circuit.
[22:54:45] <T0mW> 5..10 seconds delay in reporting latency is not a big issue, I have a max of 90 seconds per U/L
[22:55:38] <T0mW> the SQL dataset will be buffered in RAM anyway, it is typically a few hundred rows
[22:56:27] <T0mW> with sql joins, it could reach upwards of 10 thousand rows at worst.
