@andyp1per I do not see UART5RX pinned out anywhere....where is it?

No idea - maybe we should remove it from the hwdef

[Hwurzburg]

maybe it was ESC telem before they had BlueJay....but it should be removed...

Also, their recommended usages are:
UART1 (DMA enabled): GPS or CRSF...its protocol is currently MAV2....not okay for CRSF, nor for GPS since UART4 is GPS by default
UART4 (no DMA): only shown as DJI but its protocol default is GPS not DJI

I think we should (to make BF/iNav migration easy and avoid user confusion):

1. remove UART5 and mark it EMPTY since its unusable
2. set DJI protocol for UART4
3. set GPS protocol for UART1
4. change PC7 to TIM8 RCINT to allow SBUS to work even if a UART(3 in this case) is set for RC protocol

[andyp1per]

Yes agreed on 1-3. Don't agree with 4 without testing - they already have an SBUS pin out which I suspect is hardware inverted so no need for RCININT.

Actually, I do not think that the SBUS pin has every been tested with this hwdef....I do not think it can work....it has an inverter which makes it useless as a normal UART RX since this is an F405....in order for it to work, I think you MUST use the definition I propose...
