For the records, just in case someone wants to do the same, I had to
use:
/sbin/getty 115200 tty0 -n -l /bin/sh
I also had to set CONFIG_KEYBOARD_TWL4030 to get the keyboard
working. Any reason for that option not be enabled by default in
rx51_defconfig?
Additionally, after something like 25 seconds, the screen goes black and
the device stops. Any clue? Can be panel realted?
I'm guessing here, but it could be the HW watchdog kicking in if by
"device stops" you mean that serial etc also stops. Although it should
reboot, not stop...
Well, it's a stock N900, not a development board so I don't have a
serial; only the screen and the led in the left corner below the
screen. By "device stops" I mean that the screen and the led (which was
previously on) get dark and stay as is.
I also suspected a HW watchdog but 25 seconds did not sound like it. I
built a kernel without HW watchdog: same result.
Any idea regarding how I could debug that?
You can try disabling the hw watchdogs via flasher.
sudo flasher --set-rd-flags=no-omap-wd,no-ext-wd,no-lifeguard-reset
This should prevent any watchdog resets.
To restore to factory settings do
sudo flasher --disable-rd-mode
cheers,
