BBIA missing PRU GPIO Names


I’m migrating a cabe from BBB to BBIA and I’m facing a problem.
ON BBB is used the pr1_pru1_pru_r30_rX - pins P8.27 to P8-30 and P8.39 to P8.46.

On BBB the modes for this pins is mode pr1_pru1_pru_r30_X - X is from 0 to 11 - 12 PRU Outputs.
What is the mode on BBIA equivalent of the BBB ? I can’t find this on System Reference(

Thanks for helping.

The doc at the below link was provided by Jason some time back. This should give you an idea of the pin mapping between the BB Black and the BBAI.


Thanks Jon.
