Yoshita-san,

No, this is not supported on this device. Only CPU1 can write to CPU1 flash and CPU2 can write to CPU2 flash.

Hi Yoshita,

No. CPU1 cannot write to CPU2 flash bank and CPU2 cannot write to CPU1 flash bank.

Each CPU subsystem has its own flash bank, which it can read, program, and erase. Both flash banks share a single charge pump for program and erase operations. Hence, only one CPU can program or erase its flash at any given time.

Thanks,
Katta
