Hi Bruce,
beside 2x8k DRam and 12k SRam libpruio is using a further memory block
called ERam (extension or external), find details at
#saw one post on the TI E2E forum that indicated #that Remoteproc/RPMSG is not

think.
In a parallel processing architect that ability to share data quickly between
processors is paramount.With out that the ARM is
@TJF on this forum promotes a solution called libpruio that might work. I
don't know if it's fast enough though.
I thought libprio was designed to be very fast was my understanding. I Saw in
TI forum docs that UIO isn't supported in SDK Linux by TI.
I would definitely agree with below and your
Regardless of the timing, you want to store 20,000 values but I think
you've calculated correctly that you can only store 7,168 values in the 28k
of combined PRU memory and that would only be true if some of the PRU
memory wasn't used by your PRU program when it's loaded.
So are you trying to
Hello
Google Am335x PRU Support package it's got 6 labs and examples including ADC.
It's written for the SDK Linux Dennis mentioned but people have gotten these
examples to work with Linux supported in this group
There's also a Support package tar containing step by step HTML of all the
labs

Capture from what?
