I got all done as per your instructions in mode B, and the following error message appears... one thing that I am not sure whether I did well was the soldering of pad D16; the solder almost did not want to stick because I already did testing forth and back several times.Doh, I've just noticed that they are just reusing the mcp251xfd overlay from our tree. I thought they were pulling in their own.
The one configuration I think can work is:
Resistors want to be all in the B position on the back so that both chips use SPI0.
CE_1" doesn't matter.
INT_1 wants to be D16
CE_0 wants to be CE0
INT_0 wants to be D13.Code:
