Hi,
I am trying to port the "MikroTik RouterBOARD wAP G-5HacT2HnD", also
known as "wAP AC" to ath79 (it's already supported in ar71xx) and I got
stuck. I think I can't add the corresponding DTB to the kernel image,
which has to be in ELF format so that the bootloader accepts it.
So far, I get the device to boot the vmlinux.elf or the
vmlinux-initramfs.elf images and show some output on the console, but it
stops immediately. From what I have been able to find around, I suspect
that the line:
[ 0.000000] OF: fdt: No valid device tree found, continuing without
suggests that the DTB was not appended to the kernel, so it can not be
parsed and the device ends up stopping at:
[ 0.000000] Failed to get CPU node
[ 0.000000] sched_clock: 32 bits at 100 Hz, resolution 10000000ns,
wraps every 21474836475000000ns
I would like to ask you for your advice on how to generate the ELF
images so that they include the dtb, since I am not able to make it and
I can't go beyond that on supporting the device.
Please find attached the complete boot log (28 lines) and the patch I
have been working on (also at
https://github.com/rogerpueyo/openwrt/tree/ath79-mikrotik-rb-wapg-5hact2hnd_wip).
Thank you very much,
Roger
