Hello,
I am using the B-U585I-IOT02A board, which features an STM32U585 microcontroller. I am attempting to write data to the internal SRAM2 within a TFM (Trusted Firmware-M) package. However, I am encountering difficulties in accessing and writing to the memory, possibly due to security or access issues.
I have also tried utilizing the backup RAM, which is an unsecured region for writing data. Unfortunately, I still encountered issues accessing or writing to it. Could someone please provide guidance on how to write data to internal SRAM2 or backup RAM within a TFM package?
Thank you.
