Good evening all. |
| [02:36:13] |
<john> |
I just picked up a zipit2 and am going to be getting an appropriate memory card tomorrow. |
| [02:37:30] |
<john> |
Am I safe going with microSD+miniSD adapter, or is the likelyhood of getting a miniSD card that doesn't support SPI mode high enough that I should go with miniSD? |
| [02:41:08] |
<ATravelingGeek> |
I'm using a microSD card with a miniSD card adapter |
| [02:48:11] |
<unrest> |
good mornin john |
| [02:48:30] |
<unrest> |
i'm using microSD+adapter, too |
| [02:48:56] |
<unrest> |
kingston didn't work for me though - it booted, but somehow was fucked |
| [02:49:16] |
<unrest> |
now i use the kingston's adapter with a sandisc microSD and it works like a charm |
| [02:49:35] |
<john> |
Hmm, vaguely ominous. I'll keep that one in mind when I'm picking one out. |
| [02:49:59] |
<john> |
But it sounds like microSD in general is safe enough. Many thanks. |
| [02:53:15] |
<john> |
I suspect that I'll be back here soon enough, once I've got the card in hand. |
| [02:53:40] |

The default zipit image is seriously miserable; but the hardware seems pretty neat. |

<crazymonkeypants> |
I have GPIO logs up through the app starting |
| [14:18:57] |
<unrest> |
and what do they tell you? |
| [14:19:14] |
<crazymonkeypants> |
Still working on that |
| [14:19:30] |
<crazymonkeypants> |
I'm fairly close to having a reasonable map of what GPIOs are in use |
| [14:19:42] |
<crazymonkeypants> |
I found the backlight and the I2S that talks to the LPC915 |
| [14:19:48] |
<crazymonkeypants> |
which gives you battery levels |
| [14:33:14] |
<Magon> |
isnt there GPIO map on site? |
| [14:35:31] |
<crazymonkeypants> |
Not that I'm aware of |
| [14:35:36] |
<crazymonkeypants> |
If there is, I'm all ears |
| [14:35:48] |
<crazymonkeypants> |
Just going over the I2C transactions |
| [14:36:02] |
<crazymonkeypants> |
Lots of these: |
| [14:36:02] |
<crazymonkeypants> |
| | set SCL 1 bit 6 = 1, #address 0x55 |
| [14:36:02] |
<crazymonkeypants> |
| | set SCL 1 bit 7 = 0, #write data 0x02 |
| [14:36:02] |
<crazymonkeypants> |
| | set SCL 1 bit 6 = 1, #address 0x55 |
| [14:36:02] |
<crazymonkeypants> |
| | set SCL 1 bit 7 = 1, #read data 0x7b |
| [14:36:15] |
<crazymonkeypants> |
(ignore the stuff on the left, that's just my protocol decoder) |
| [14:36:41] |
<crazymonkeypants> |
Which matches up perfectly with the zipit-peeks-pokes document's description of reading the battery voltage from the LPC915 |
| [14:36:56] |
<crazymonkeypants> |
There's the Wolfson setup, which is unsurprising |
| [14:37:16] |
<crazymonkeypants> |
There are a bunch of attempts to talk to address 0x50, which doesn't respond |
| [14:38:06] |
<crazymonkeypants> |
But there's also a long write to the LPC915 that I'm not making any sense of yet |
| [14:50:00] |

Hm, no, you didn't |

This thing "ANA TI 68k A3RF" is a TI battery charger chip |

<crazymonkeypants> |
Here is today's Mystery Question |
| [15:10:38] |
<crazymonkeypants> |
The Zipit app writes to address 0x83 in the LPC915, and it sends these 32 bytes: |
| [15:10:43] |
<crazymonkeypants> |
60 dc a3 36 3e 3a 4c 85 - 50 2e 9c db e8 f3 8b b0 |
| [15:10:43] |
<crazymonkeypants> |
b6 65 fe c6 9e ea 49 b9 - f9 56 7d d6 29 94 1d 01 |
| [15:10:48] |
<crazymonkeypants> |
What Are They? |
| [15:11:29] |
<g1powermac_PB> |
interesting |
| [15:16:33] |
<crazymonkeypants> |
They don't seem to decode to sensible 8051 opcodes. They're not obviously text to me. |
| [15:16:49] |
<crazymonkeypants> |
They're too dense to be preferenes, and there's a prefs xml file anyway |
| [15:17:06] |
<crazymonkeypants> |
They don't plot to a curve or look anything like battery calibration data that I know of |
| [15:17:24] |
* |
g1powermac_PB needs to crack open my new zipit, see if its the new board or the old one |
| [15:17:39] |
<crazymonkeypants> |
The 0x01 at the end is a bit suspicious, but I tried a few quick calculations and I couldn't find a checksum or a length indicator in there |
| [15:19:28] |
<crazymonkeypants> |
It never read from there, only wrote |
| [15:19:55] |
<g1powermac_PB> |
hmm |
| [15:22:23] |
<Switchcat> |
whats the differences in the boards with the z2? |
| [15:23:24] |
<g1powermac_PB> |
from what I know, the new version just has all the fixes built into the board |
| [15:23:29] |
<g1powermac_PB> |
everything else is the same |
| [15:26:12] |
<Switchcat> |
oh I thought those 'fixes' (you mean the wires?) were things with the original z1 not the z2 |
| [15:26:56] |
<g1powermac_PB> |
nope |
| [15:27:07] |
<g1powermac_PB> |
the wires are from the original z2 boards |

<g1powermac_PB> |
I'll be putting up the jtag info soon |

I'm going to write an expect script to watch the GPIOs so that I can fool around |
| [15:59:05] |

<crazymonkeypants> |
I need to get GPSfan to build me a new gpio driver with some modified logging; the current spew is hard to wade through |
| [16:01:08] |
* |
g1powermac_PB will be working on doing up usb device stuff |
| [16:01:23] |
<g1powermac_PB> |
so I can then work on replacing the wifi driver with an open source one |
| [16:01:36] |
<g1powermac_PB> |
which will then let us upgrade the kernel |
| [16:03:34] |

g1powermac_PB wonders why my zipit sf page never shows up in google searches. . . |
| [16:07:53] |
<crazymonkeypants> |
Who links to it? |
| [16:08:05] |
<g1powermac_PB> |
currently it seems just irc loggers |
| [16:09:14] |
<crazymonkeypants> |
g1: what's the USB stuff required for? |
| [16:09:36] |
<g1powermac_PB> |
so you can do usb gadget ethernet |
| [16:09:55] |
<g1powermac_PB> |
so you can still ssh into the zipit but bypass the wireless allowing you to work on the wireless stuff |
| [16:10:45] |
<crazymonkeypants> |
Got it; without requiring hacking the unit apart for serial |
| [16:10:52] |
<g1powermac_PB> |
yea |
| [16:11:00] |
<crazymonkeypants> |
That means that folks will need to make a cable, but that's not too bad |
| [16:11:02] |
<g1powermac_PB> |
though I'll be doing that to get the usb gadget stuff to work :-) |
| [16:11:25] |
<g1powermac_PB> |
yea, once I get the usb gadget stuff working, all you need is the cable and a replacement kernel |
| [16:11:41] |
<g1powermac_PB> |
which can easily be done I think from the sd card directly |
| [16:12:59] |
<crazymonkeypants> |
You could write a z2script that updated the mtd, I'm sure. |
| [16:13:16] |
<g1powermac_PB> |
yea, thats what I'm thinking |
| [16:41:01] |
<GPSFan> |
crazymonkeypants: if you have a patch against the gpio_driver.c I can build you a now module. |
| [16:41:47] |
<GPSFan> |
crazymonkeypants: or just edit the .c file, passtebin it and I'll build it from there. |
| [16:43:36] |
<crazymonkeypants> |
Wilco. I will probably do something disgusting so that I can binary patch it to get the filtering I want |
| [16:43:53] |
<crazymonkeypants> |
I'm using cut and paste to sniff the GPIOs |
| [16:44:06] |
<crazymonkeypants> |
Found most of the keyboard special buttons now |
| [16:45:33] |
<GPSFan> |
crazymonkeypants: the only gotcha is that you have to document what you are doing on either g1powermac's or the edev wiki. |
| [16:46:06] |
<crazymonkeypants> |
Sure; I just don't want to rush into print |
| [16:46:42] |
<crazymonkeypants> |
Here, let me pastebin the GPIO map I have |

yeah it's an ARM based distro that seems to have brought together a number of groups |

I'm not sure the beagleboard counts as expensiuve |
| [17:42:06] |
<crazymonkeypants> |
(I don't actually see anything about recommended hardware) |
| [17:46:20] |

in comparison to a $36-$50 Z2, lots of stuff is expensive. :) |

mm, true |

if we can get more people developing a unified distro with a z2 as a cheap entry point towards making it work, the better. :) |
