Just tried the debian trixie image that you suggested (well actually you suggested the kernel, but I just flashed the whole image).I see it is asm1064 chip, I recently got a M.2 M-key adapter with asm1166, in other SoC/SBC, so far so good, but I was prepared for troubles. I also boot from eMMC (U-Boot bootloader is also there). Kernel is 6.1 based, but also 6.15 mainline based works.
Maybe you could use Debian Testing/Trixie standard kernel. I use that on RPi3B, no issues. see https://raspi.debian.net/tested-images/ for config.txt and cmdline.txt.
Or maybe use https://github.com/pftf/RPi4
And/or ask Waveshare for help.
It worked!
Thank you so much for taking the time to reply.
