AM620-Q1: Can the Sitara AM62-Q1 run from Flash SW only or external RAM?

Hi,

What software are you going to run on AM620-Q1, Linux, RTOS, or something else?

It is planned to run Free RTOS

I am routing your query to our RTOS expert for comments.

The AM62X SOC supports the XIP mode and the core runs from the direct OSPI flash .

The XIP example is not supported in the AM62X MCU+SDK  .

While XIP (execute In Place) is technically possible from OSPI, it has significant performance limitations due to the slower access time for the flash as compared to DDR.

TI recommends copying the application from Flash to DDR memory and executing from there to achieve reliable performance. 

The AM62X does not support direct executes code from the SRAM on the GPMC .
