Revision as of 19:40, 22 November 2018
WARNING: This device is not recommended for future use with postmarketOS due to its armhf architecture. Alpine Linux (the distribution that postmarketOS extends) pmaports#599 has been considering dropping it. The processor of the device may support the armv7 architecture. If so, you can modify the device package and change the architecture accordingly. |

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).
Get UART working, then test basic DTS with just basics to get earlycon/earlyprintk working:
- used voltage is 1.8V
- needed resistor is *probably* 619kΩ
- unknown name of the port in original kernel, candidates are ttyMSM0, tty0, ttyHS0, ttyHSL0 and ttyGS0
- trying to get UART on 0xa9a00000 (ttyMSM0)
- dtb probably misses clocks, maybe interrupts and other things
This dtb file goal is to get working UART, nothing more, rest of the work will be continued on regular git repository when/if UART starts working |
Useful links (mainly dts stuff)
The Mainline Kernel – our docs about mainlining
Qualcomm mainline porting — our sparse docs about Qualcomm mainlining
Qualcomm SOC Mainlining Project – sadly no MSM7227a
Documentation/devicetree/ inside linux kernel files, should contain newest documentation about dts files, should be most reliable source of information
How to enter flash mode
Press power button and hold home button and VOL-, then press VOL+ to continue
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
