u-boot support for pins

Yeah tx, and rx are staggered two pins apart in the pdf file I have here.
what are the Px header assignments, or gpioxx_yy nomenclature assignments ?

Agreed. And the pins are E18 and E17 for DCAN1_RX/TX on the BBB schematic. These are the pins the TI pinmux tools says use. So, trying to use these two pins for CAN1 because we don’t have the P9 expansion header.

That is just the first step in this CAN bring up process for a custom BBB board that doesn’t have a P9 expansion header. So I agree.

I still have a question for Robert, why is the P9 expansion header being used for then CAN on the most recent release instead of the AM335X CAN0 and CAN1 RX/TX pins D17/D18 and E17/E18?

Thx, Tracy
