Is there a simple script example on Linux side to test MPU <-> CPU comm ?

[K.Ata15]

Hello,

I am building the firmware on the M4 core. I have allready modified the 'demo_launcher.py' script to launch my code via the GUI (for demonstration purposes). As the Linux application will be built by somebody else, i only need to do the M4 firmware and use simple script to send and receive messages. I see a lot of info about on the Wiki about the protocol, but my knowledge of Linux is not that great to code this from scratch.

Is there a basic example script that i can use and modify for my purpose ? I see a C app here:

https://github.com/STMicroelectronics/meta-st-openstlinux/blob/4e36cf0c7c7bdb24700a990f73afcda84cdcf0cf/recipes-samples/ai-nn-application/ai-hand-char-reco-launcher/ai_char_reco_launcher.c

that is used by the 'demo_launcher.py', but i don't currently have a PC set to build this.

Thank you!

K.

Hi @K.Ata15​ 

I guess the example OpenAMP_TTY_echo is the example code you are looking for.

Please refer to this page for details where to find and how to play with it :

Hope it help
