## Summary This PR intends to fix the RTC WDT deinitialization on the NuttX startup. Write protection must be disabled before performing changes to the WDT registers. Furthermore, the routine was resetting the wrong field from the RTC WDT register. The `RTC_CNTL_WDT_FLASHBOOT_MOD_EN` field relates to Flash Boot Protection and it is enabled by the 1st stage bootloader. The 2nd stage bootloader takes care of disabling it. Then the 2nd stage bootloader enables the RTC WDT for checking the startup sequence of the application image. ## Impact Now it is now possible to once again enable the RTC WDT on the ESP32 2nd stage bootloader. ## Testing Tested `esp32-wrover-kit:nsh` with ESP-IDF vanilla 2nd stage bootloader. -- This is an automated message from the Apache Git Service.
