Re: [beagleboard] PRU examples are half there

BTW, I seem to remember that I had to modify the code to work because RPMSG use to use mailbox to exchange messages, but that was changed to use Interrupts. I believe Jason Reeder from TI helped me get this working. Regards, John > On May 7, 2018, at 12:47 PM, Mark A. Yoder

Re: [beagleboard] PRU examples are half there

Yeah, I haven’t worked on this for a while, but from what I remember, the ARM side sends out 200 ping messages to the PRU and the PRU responds to each interrupt with a reply, which the ARM side prints out. Look for the PING example for the PRU, load the firmware and then load this Kernel

Yes Sir, I got a fellow zmatt, Mr. Dennis, and a fellow on Adafruit-Forums all to give advice. Although I ended up taking another route, they all had supportive advice I could follow and adhere to. Seth P.S. Thank you for the ideas and new Capes. I got two on backorder as I type this

All worked out now as part of https://www.hackster.io/silver2row/beaglebone-black-and-l298-motor-driver-in-python-2156be ? Good timing as BeagleBoard.org Motor Cape ( https://github.com/beagleboard/capes/blob/master/beaglebone/designs/Motor/Motor_Cape_sch.pdf, https://beagleboard.org/capes) is

Yup, all I see is the PRU code, no ARM code. --Mark On Sunday, May 6, 2018 at 11:28:40 AM UTC-4, Jason Kridner wrote: > > Did you look at http://git.ti.com/pru-software-support-package ? > > On May 4, 2018, at 5:08 PM, Mark A. Yoder > wrote: > > I'm starting to build up
