    Hi Nico,

    If you're using a full linux OS on your BBB, then I don't think you can start the application from u-boot (I don't think this have been tested)...
    You can try using the go & bootm commands in u-boot environment (in am335x_evm.h) to run the PRU binary, but I am not sure if this won't mess with booting the kernel on a later stage.

    You could check the TI RTOS, which provides u-boot with the possibility to boot applications from it..

    Best Regards,
    Yordan
