Hello,
I am trying to send data from the ARM processor to the PRU using rpmsg. After following Greg’s guide found here: https://github.com/Greg-R/pruadc1/blob/master/doc/PRUADC1latex/PRUADC1.pdf, I am still unable to see any rpmsg_pru* files in the dev folder. Are there additional instructions for creating the rpmsg_pru* files for newer images and kernels?
