Thanks for the bug, the firmware wasn't getting copied to the initramfs, just pushed a fix, and should hit the apt repo shortly: https://github.com/rcn-ee/repos/commit/2922f56ce8ab70771944f7eb99d7fd10f8a52b6a [ 10.478212] ti-pruss 4a300000.pruss: creating PRU cores and other child platform devices [ 10.478410] irq: no irq domain found for /ocp/pruss@4a300000/intc@4a320000 !
