To do
informations below may be chaotic and change often |
SMSM_RESET
Most annoying problem sunce everything on the phone has to be done within 2 minutes. After about 2mins 22secs phone reboots with dmesg showing SMSM: Modem SMSM state changed to SMSM_RESET This message is hardcoded into arch/arm/mach-msm/smd.c
Probably caused my modem, check all MODEM and MSM*_MODEM_* related options in menuconfig (there is one called reset, one reboot and one just modem) or find binary blobs if possible.
Touch screen
The screen as well as two touch buttons (menu and back) are combined together as /dev/input/event1. It displays some sort of animation when pressing buttons in postmarket demos window in weston but only for first press or two. weston-calibrate does not work
Home button and volume buttons are /dev/input/event1, where power button is recognised as /dev/input/event6
Mainline
Currently we have working 2.6 kernel, no DTS files for qcom-msm7227a.
Get data form all over the kernel source code (mainly arch/mach-msm/board-<board name>.c for starters and recreate it in .dts file(s).
Useful links (mainly dts stuff)
The Mainline Kernel – our docs about mainlining
Qualcomm mainline porting — our sparse docs about Qualcomm mainlining
Device Tree – The Disaster so Far(pdf) – introduction to DT and basic knowledge how to move from board files do DT
Device Tree for dummies(pdf) – a little bit more complex infoa bout DT files
Halium project docs on mainlining – has a nice list where to look for ready solutions
Qualcomm SOC Mainlining Project – sadly no MSM7227a
Allwinner SOC Mainlining Project – not useful for this phone
Documentation/devicetree/ inside linux kernel files, should contain newest documentation about dts files, should be most reliable source of information
S6500d fork

How to enter flash mode
Press power button and hold home button and VOL-
Alternatively, plug in microUSB plug with GND and ID pins connected through 300KΩ resistor. (so-called USB jig)
Installation
For now see Installation Guide and Flashing on Porting to a new device
