I am using NUCLEO L476RG board to test IWDG is frozen in Standby mode. I did following steps in below
- set IWDG_STDBY bit in FLASH_OPTR to zero
- Initialize Iwdg will reset in 5s
- Start Standby mode by HAL library
the board was reseted in 5s, but it was not reseted when i retried in the second or after.
please show me how to frozen IWDG without reset in the fist time?
