trying to bring up aw-A20-som, how to enable more verbose debug log from booting kernel ?

Hello,

 

I am working on a board that is essentially the AW-A20-SOM with some peripherals on a backplane in which the AW-A20-SOM plugs into. I built armbian from source in the recommended VM configuration using the existing aw-som-a20.csc config.

It boots and runs a special build that is installed in eMMC but I want to create an armbian build for it. First I want to boot it from SD card so I had just to change the following

With this change, u-boot starts and loads the linux kernel from SDcard but then ends up in a boot loop with no messages from the linux kernel at all. It just reboots after 45 seconds.

I guess my next step is to enable more verbose debug output from the linux kernel to see where it gets stuck, but I can't figure how to do that so far... I thought adding verbose or debug to the bootargs would do that but I guess the armbian boot process is much more complex.

replying to my own question, I found that I can do at the u-boot prompt 

setenv extraargs debug

to increase the log level. now this is my current boot log

Spoiler 

=> setenv extraargs "debug ignore_loglevel"
=> boot

it would seem like there is something stuck with the AXP209 ?

more debug with booting with extraargs "debug initcall_debug"

after [   13.181458] initcall axp20x_pctl_driver_init+0x0/0xfff [pinctrl_axp209] returned 0 after 39165 usecs

I thought axp20 pinctrl was hanging but it looks like it's init returns

we are just hung after that... ??

ok so I got it booting fully.

I just created a very limited device tree for u boot and linux, that only had what I know is on the board and used. Eventually it booted.

I thought it was stuck at some point but after the logs showing the rootfs was mounted an dsome other stuff. I figured the 32GB partitions might be in the process of being resized and remounted... and that was it.

 

I'll have to clean up the patch files I made.

Next experiment with I2S and some of the other hardware peripherals on that board...

 

Cheers, thanks for the help !
