[Bug]: CanMV v1.1 board doesn't seem to handle HDMI and/or primary camera properly

[kelas]

What happened

A vanilla canmv image built from sdk 1.4 works fine on 1.0 revision of the board (aka green pcb), but on 1.1 (brown pcb) i get a blank HDMI output (pink screen with occasional artifacts)

what am i doing wrong?

Reproduction steps

see above

Hardware board

canmv230 1.1 board (brown pcb)

Software version

1.4 (latest)

Bug frequency

No response

Anything else

I also noticed that there are now two CavMV board configs in menuconfig (one marked zero, second without suffixes) but they don't seem to make any difference in the codebase, i.e. the setting is presumably NOP in 1.4
