Hi, I am just learning Beaglebone and have set up a Debian 10 image on a recently purchased Beaglebone Black wireless. I am following the Molloy's book chapter 15 to learn PRU. However, it seems rproc module has not loaded the PRU. Is there an additional step to allow use of the PRUs? What should I look at to debug this issue? Thanks in advance.
