ERROR: pru-rproc driver not loaded

Following the documentation here I just installed a fresh Debian 9.5 image onto my BeagleBone Blue’s SD card. And then ran apt update and also updated the kernel to 4.14.56-ti-rt-r64.

I did this all becuase one of the tests run with rc_test_drivers was failing. And it is still failing. Here’s the output from the tests:

I’ve tried several version different ISO images using Debian 9.5 and 9.4. Also tried real-time kernels and regular kernels, but nothing seems to get rid of this error.

Does anyone have any ideas on how to fix this?

I also tried upgrading to kernel 4.19.59-ti-rt-r25 to no avail. :frowning:
