AM623: How does the M kernel operate on a particular physical address to write data?

The idea is that the M core writes data to the physical memory from 0x9CC00000 to 0x9CCC0000 and the A core reads it

Hello,

Thanks for reaching out to Texas Instruments E2E support forum.

Can you please tell us are you getting any error while trying to write value to memory address 0x9CC00000?

From the above query, I understood that the data is not getting overwritten to the specified memory address. Is this understanding correct?

Also can you please share the version of MCU+SDK used?

Which method are you using for board initialization? Is it SBL or SPL?

Using this version of sdk, as for SBL and SPL how to check, it is currently through the firmware to start this program

Hello,

Thanks for sharing above details.

Please refer to the below links for EVM initialization.

SBL initialization - EVM_FLASH_SOC_INIT 

SPL initialization - EVM_SOC_INIT 

Please refer to the above links to confirm which method of board initialization is used.

I am assuming you are using the SPL flow and running the M4F firmware and trying to write value at specific memory location.

Yes, I use SPL

Ok, thank you.
