AM2431: PRU-ICSS code

inno

Part Number: AM2431

I have been using the sitara am437x for a while now, and I am wondering if PRUs in 24 and am437x have any differences : will a code that runs on sitara am437x PRU run on the 2431 pru ? are they exactly the same ?

Hi inno,

The ICSS subsystems are different on the AM437x (ICSS-M and ICSS-L) and AM243x (ICSS-G), so these differences need to be taken into account.

Please see details here: https://software-dl.ti.com/processor-sdk-linux/esd/AM65X/08_00_00_04/exports/docs/common/PRU-ICSS/Overview.html#pru-differences-between-devices

The PRU instruction set and format is identical on all devices, with the following exceptions:

New XCHG instruction on PRU_ICSSG devices
New Task Swap enable/disable instructions on PRU_ICSSG devices

Regards,
Frank
