Hello @Hariharan1 

Could you please share more details?

I am nott sure if you are referring to Cortex M or Cortex A, because The Cortex M has only access to TCM, not cortex A.

Also, If you want to run an application in DDR from cortex M you can find information in the SDK from MCUXpresso SDK.

Best regards.

Salas.

Yeah, I am using Cortex a53 Processor. I.MX8 Mini has available TCM memory for Both Processor. You can check it out in Reference manual. You may get clarity. In Cortex a53 TCM memory address starting from 0x007E0000 totally we have 256 KB
