I recently ran Hampi and experienced the same kind of issue.
DRAWS board was not found while it was ok with the same hardware Rpi + DRAWS when running nwdr16 Linux image.
After exchanging /boot/config.txt file with the one from nwdr distro, then DRAWS was found on Hampi distro.
After a lot of trials and with Basil n7nix help, we found that in file config.txt the two following lines just before the line with [pi4] should be removed :
# Enable audio (loads snd_bcm2835)
The important thing is that instruction line :
should never occur after a line with
which is already present in [all] paragraph.
