Help needed with p-boot

[dukla2000]

I have been trying to get @megous  p-boot bootloader to work, for fun and also to try benefit from the safety fixes he has put in p-boot.

But so far I have no success. In short I have re-worked his example directory to try be my working config to be able to boot mobian from an SDcard and pmOS from the eMMC. I have got p-boot installed on the SDcard and at initial boot I get the p-boot menu screen with my 2 options, but selecting either of them I get the red LED temporarily then it goes out and neither OS ever loads sufficiently to show on the screen.

So obviously my boot.conf is duff but I am not sure why.

My boot.conf:

Code:

#
# Boot configurations for PinePhone 1.2
#
# Some usefult bootargs flags:
#   - quiet loglevel=0
#   - console=tty1
#   - console=ttyS0,115200
#   - root=/dev/mmcblk2p2 rootfstype=f2fs rootflags=fastboot rootwait rw
#   - panic=3
#   - init=/bin/tablet-init
#   - initcall_debug
#   - earlycon=ns16550a,mmio32,0x01c28000 loglevel=15
#   - trace_event=regulator:*,clock:*,clk:*,gpio:* trace_buf_size=40M
#   - video=HDMI-A-1:d
#   - video=DSI-1:d
#   - fbcon=nodefer
#
# boot name is up to 36 chars

device_id = pp3 (PP 1.2a)

no          = 0
  name      = mobian from SDcard
  atf       = fw.bin
  dtb       = mobian/board.dtb
  linux     = mobian/Image

  splash    = files/xnux.argb

no          = 1
  name      = postmarketOS from eMMC
  atf       = fw.bin
  linux     = pmOS/Image

  splash    = files/xnux.argb

The bootargs I copied from the respective boot.cmd files and yes I did unzip the mobian kernel.

Output from my p-boot-conf:

Any help/hints gratefully received.

Red light is turned off by the kernel, so kernel is starting. But it may be failing for some reason afterwards. You should see why if you increase the loglevel and use the serial console.

Thanks - appreciate response and even more so your great contributions to the PP.

I don't have a serial console cable so will just have to play with options "blind".

OK, have got to the point where I can boot into either mobian or pmOS, but I don't get a gui on the phone for either of them!!! I can ssh in to either though.

I can't see any obvious problems in either log file which is irksome - need to try tweaking the kernel command lines a bit more but not sure what is best.

For the record mobian tries to map p1 to /boot in fstab so removed that, and for good measure (as I am running the f2fs version of mobian) I have added rootfstype=f2fs to the mobian start line in boot.conf.

@megous  - I presume the p-boot partition (target of p-boot-conf, e.g. /dev/mmcblk0p1 on my PP SDcard) is not usable by us mere mortals? I can't even mount it. Also is dtb2 used by the released p-boot (in boot.conf) - I see you have it in the 13 system setup?

Yes dtb2 is supported by the public version of p-boot. If you can't get the display, the answer will be in dmesg, most probably.
