Reset RAM via MCU

Hey Team,

Is there a way to clear the DSP RAM via SPI from a MCU ? The datasheet says that after a hardware reset the RAM is not guaranteed to be cleared.
I implemented a DSP firmware update mechanism on my board that saves an image of my new ADAU firmware (generated by Sigma Studio) via a network connection on the MCU-flash and after a reboot of the system should re-initialize the DSP with the new firmware, but it does not yet seem to work and I am wondering if this has something to do with the RAM not beeing cleared properly.
So my next step would be to properly de-initialize the DSP and MCU (and other ICs) to get a "clean" system before I re-initialize everything after the bootloader of my system jumps back into the firmware.

Help would be much appreciated!

Regards,
Max
