| 00:16.28 | okias | it was the spi! :D |
| 00:16.29 | okias | hoho! |
| 00:16.41 | okias | anyway, how to simply find out, what regulator does use SDIO slot? |
| 00:36.29 | Russ | schematic |
| 00:36.33 | Russ | device tree |
| 00:36.49 | Russ | /sys |
| 00:36.57 | Russ | kernel log messages |

| 01:58.06 | okias | Russ: well, it's not documented yet |
| 01:58.32 | okias | Russ: so, first SD work only when you load system from it (because it can't power itself without wince) |
| 01:58.38 | Russ | time to pull out the volt meter and start probing traces |
| 01:59.14 | Russ | not knowing what is hooked up to what regulator wise is a scary thing, its really easy to blow up a board that way |
| 01:59.18 | Russ | so probe away |
| 01:59.39 | okias | well, maybe that regulator is even mainline, but no idea how it's controlled :P |
| 02:00.00 | okias | some wince debug could be usefull.. |
| 02:00.06 | Russ | just look at the board |
| 02:00.08 | Russ | what chips are there |
| 02:00.12 | Russ | then look up the datasheets |
| 02:00.22 | okias | :( I have it like device complete |
| 02:00.34 | okias | not sure if I can disassemble it without damaging |
| 02:00.46 | Russ | I know nothing about wince debugging |
| 02:01.08 | okias | but you have totally right |
| 02:01.18 | okias | checking chip on board is easiest solution |
| 02:01.19 | Russ | maybe you can find pictures online of someone else who took it apart? |
| 02:01.41 | okias | Russ: tried, I can try harder.. it's loox c550 |
| 02:01.45 | Russ | and then if you are able to see what i2c messages wince is sending, you can actually make sense of them? |
| 02:02.26 | okias | Russ: not sure, but I can learn probably :P |
| 02:02.35 | Russ | can you buy a broken one on ebay? |
| 02:05.32 | okias | Russ: well, I see clearly screws, so I'll ask friend for this "star" screwdriver :) |
| 02:05.51 | okias | In free time, there is lot other parts to port :D |
| 02:06.28 | okias | anyway I feel it work better with 3.x kernels than with 2.6.27 |
| 02:06.56 | okias | time to build some small userspace |
