DA14580软复位

Hi,

Can I reset my application through software without losing firmware inside sys-RAM of DA14580?

I have tried through watchdog also by setting "SYSRESETREQ" bit of register "AIRCR". It resets controller and removes firmware inside sys-RAM. I want to prevent my firmware inside sys-RAM and reset my application to main_func( ) function whenever some hard fault or some unhand able fault occurs. I am not using OTP. External controller downloads firmware into DA14580 through UART.

can you help me on it?

thanks?
