I haven't tried the SMD board in a while, it's possible something broke,
but see below...

The adv7180 driver in 5.3.x doesn't support seq-bt, only alternate. So
pad format should be "[fmt:UYVY2X8/720x240 field:alternate]".

This probably means there was a pad format mismatch. Try enabling
dynamic debug.
