AM2434: Inquery about ICSS running on RTOS on top of AM2x compared with AM335x, AM64x

Hi Jack,

Jack said:

The ICSS on AM335x appears to operate on TI-RTOS, and the ICSS on AM24xx appears to operate on FreeRTOS.

This is not true, its the ARM core which runs RTOS not the PRU core, The firmware running on PRU cores are written in PRU assembly.

AM335x sdk supported TI-RTOS on application core, but AM243x sitara sdk supports FreeRTOS and No-RTOS on ARM cores.

Is there a difference between the two? Are the ICSS of AM24xxx and AM64xx the same?

The ICSS on AM243x and AM64x are the same. AM335x has older version of ICSSG. Please go through the datasheets of each to look into further details.
