@Dennis thanks for clarification I think his previous post a week ago mentioned Bb AI but Bruce please don’t assume everyone read your recent previous post is my advice.
So you need to narrow down something after you reply to Dennis confirming you have correct Linux .
Start with an unmodified example a simple one IRQ are cool but might need resources allocated in the DTS file. How about lab 4 from PRU support package 5.8 . Use binaries.
Also Confirm you found the guidelines on these examples and the RPMSg quick start guide for Linux please read it.
We need console messages from Linux prompt of errors and details of I did such then saw such. A detailed screen capture.
I don’t own an AI and expecting someone to get your code and run it I can’t do it is all I’m going to say. I can help guide you and MAYBE try it on BBWhite if I have time. In theory the AM 5729 should work the same.
The binaries are in the TI AM 57xx Linux SDK its 3 Gig and requires a Linux machine. I can only help you with that if you’re using a PRU cookbook example I’m unfamiliar the SDK guidelines support binaries for PRU and ARM and cross compiled Linux target compiled source code.
As a beginner I suggest dropping binaries on ARM to be loaded to the PRU and dropping the ARM Linux application binary into filesystem.
I won’t even attempt to help you start compilation of any code especially if it’s changed or gaze upon it without having your environment speculating why it won’t compile.
I respect your decision if you do choose to disregard my advice and try the Cookbook example but feel it’s an exercise in frustration to do this by email without us having hardware and your environment. Too many unknowns.
Most important what’s it doing?
The original post was a link to all the code. It is at: https://gitlab.com/brucechidester/pru-messaging-example
The Readme.txt file explains what I would like the solution to do.
Better idea to use an example that’s documented
2 This is the BB AI correct?
I do not know what this question means…please clarify.
3 Where did this code come from?
I wrote this code from other examples attempting to get it to work.
Which examples ? How would we know?
4 What is your ARM OS and version. Compiler host details
BeagleBoard.org Debian Buster IoT Image 2020-04-06, 4.19.94-ti-r42. A fresh release from https://beagleboard.org/latest-images
5 Brief Summary of what you tried with important details(start from 5 and work backwards trying to keep it clear and concise)
I was trying several examples from everywhere and I cannot get any messaging example to work. The TI messaging examples that they provide do not include the application code that interacts with the PRU messaging. The UIO to Remote Proc change has made many of the examples out of date and it is getting frustrating trying to figure out the correct solution for the latest disto for the BBB.
This my whole point. Read this above like you were us.
What’s out of date? The SDK guidelines are current for RPSg/ Rproc.
What code are you modifying? What how-to/ guidelines/ book are you using ?
Last week’s email I described all this in detail to you step by step at least for TI Linux SDK.
Of you’re using something else tell us so some besides me who’s knowledgeable doing that may comment.
I have know idea whether the PRU cookbook is up to date for AM5729
I do know TI invented, designed RPROC and the documents are valid and correct even though this concept is years old.
Hopefully it’s more clear. Download the 3g tar Am57xx Linux SDK it’s got documents. Ask specific questions. It’s been done successfully my at least 3 people on Beaglebone Black.
Hopefully someone can help support what your doing if it’s not SDK code.
