I see only 335x & 57x support Profibus Master & Slave, Does anyone know about AM437X supported or will support Profibus Master & Slave?

Hi , AM4379 can support Profibus on PRU-ICSS1 (but not in PRU-ICSS0). However, our AM4379 IDK board doesn't have a serial port for Profibus connection. Users could add RS-485 to their custom boards.

thank you,
Paula

Thank for you reply. If i add RS485 on my own AM4377 board to use Profibus, could i use "PRU-ICSS-PROFIBUS-MASTER" & "PRU-ICSS-PROFIBUS-SALVE" to implement Prifibus communication or i need to buy a protol packge form third part. For i see that "PRU-ICSS-PROFIBUS-MASTER" & "PRU-ICSS-PROFIBUS-SALVE" specify support am335x or am52xx but not am437x. Thank you!

Hi, if you use AM4379 and add RS485 you will need to modify PRU-ICSS Profibus slave to work with AM437x. You can search in the code all the places in which #define AM335x (or SOC_AM335, in other words search for AM3) is used and most likely you would need to add similar code/changes for AM437x.

You can also check another protocol such us EtherCAT slave, which includes AM437x, in order to have and idea on how it is handled.

thank you,

Paula
