All in all they went OK, as far as I can tell!

+U8230 confirmed ;)

Dmesg via ADB shell

- On Cm7
- On FTB

Congrats on successful running! :)

Thanks for testing on other roms! Good to know they boot fine.

Can you please confirm that you also can't loan phone when USB cable is not plugged in? (And phone hangs and reboots when you unplug usb cable?)

And obviously you don't have touchscreen working on either of those roms, right? :)

Yes, both are present, and yes, the touchscreen ain't on.

Achieved good progress - migrated USB system from "usb function" type (as was in Pulse's 2.6.29 kernel) to "usb gadget" type (as in all 2.6.32 devices). Have adb via it as well.

It solved freeze/reboot issues when plugging/unplugging usb cable. So as a result I can boot device unplugged. Plug it later, unplug again - no issues I noticed.

Experimenting with CM7, load it to unlock screen - can't pass it - no touchscreen :)

How to do that? I didn't find anything useful in Settings menu... CM7.1RC1
Unlock security is off, but it still requires to move circle via touchscreen, don't know how to to it via jogball or keypad...

Looks it's patch from Android space, not kernel. My issue is in kernel level... Thanks anyway.

The issue with touchscreen is that.

Our driver is: synaptics_i2c_rmi_tm1319.c
It's not changed much between kernel versions 27, 29 and 32.

It was working in versions 27 and 29 with settings vreg="gp6" and gpio=57.

This has changed in v32 I'm playing with (huawei u8150) to:
"gp5" and gpio=29. This neither crash nor work.

But I don't trust those settings as touchscreen could not even be properly detected in probe().
Also those settings are used on msm7x25 boards since at least 2.6.29 kernels (u8110 pulse-Mini). So I think those are propagated somewhat by default to our board, even if our chipset is not supported in that 32 kernel.

So, if I revert back to "gp6" (and remain gpio=29), touchscreen got successfully detected in probe(), register itself as an input device. But no output from that device...
If I change gpio=57 in addition to "gp6", kernel hangs on probe() of the touchscreen. (Somewhere in vreg_enable).

-----
I experimented with that u8150 huawei kernel, plain vanilla Code Aurora v32 kernel, also with LG GW620 v32 kernel (same chipset; openeve project, based on official LG v32 kernel, based in turn on Code Aurora) - nearly the same issues, no luck.

If anyone have slightest idea what might be wrong, please let me know.

Here it is: pulse-hw2.6.32_v0.04.img
This image is for CM7.1RC. Extract kernel and repackage to try to use with other roms.

Changes:
- touchscreen works
- transitioned to "usb gadget" code. (Doesn't crash when unplugged from usb.)

Mass storage works, adb, sd card.

Not intended to work in this snapshot: sound, bluetooth, camera, sensors and anything else.

nice piece of work!
i can't try it out now because my pulse is in the service center (trackball was full of s**t and it wouldn't move)
but i'm sure that you will manage to get it working.
just remember that your work is highly appreciated here in the community :)
