Hello,

Is this available still?

uboot_overlay_pru=AM335X-PRU-UIO-00A0.dtbo

I looked in /boot/uEnv.txt and I did not find the uboot_overlay_pru= section.

Seth

P.S. I was going to install things to make an Optical Encoder work but I have no PRU so far to use. Is there another type of resource to use for Optical Encoders for the BBB?

Can I just type in uboot_overlay_pru= on one of the lines to handle this instance:

uboot_overlay_pru=AM335X-PRU-UIO-00A0.dtbo ?

I will test it out. In the meantime, I just wanted to let people know that my uEnv.txt file does not come w/ that entry listed.

Yes…

Official images have had it listed for-ever…
