ESP32 Forum

Hi All,

Newbie to ESP32 programming.
Accidentally programmed the application firmware bin on the memory location 0x1000 using the following command,
esptool --chip ESP32 -p COM32 --before default_reset --after hard_reset write_flash 0x1000 esp32.bin

Seem i overwritten the bootloader at 0x1000
I am getting the following error from the device continuously,

rst:0x10 (RTCWDT_RTC_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT)
flash read err, 1000
ets_main.c 371

How to i reprogram the bootloader at 0x1000. Please help.

What SDK do you use? If esp-idf, simply run 'idf.py flash'.
