Here's my implementation, in case someone needs something similar or in
case someone wants to review and criticize.
On the ARM Side:

// Communication with PRU is through a ring buffer in the

You will need to use a GPIO pin and manually toggle it.
If you need precise speed control, you can task a PRU unit to toggle the pins
with precise timing.

On booting from the eMMC, I was having a problem whereby the kernel was

I think you will run into concurrency issues.
The operations to increment the buffer need to be atomic, but they are not.
While you perform the read / add / modulus / write in the Arm, then PRU can add
a new message and change the value.
The ring buffer can get corrupt.
I would set a flag in
Not sure if there is a better way, but you could do a readTextFile, store the
data in a string, append your data to the string, then writeTextFile the data
to a file. This would work well until your text files start getting large,
after which things will start getting slow and memory-intensive.
