Im trying to rewrite flash status at ESP32D0WDQ6 using esptool but I has no success.
The esptool show me that there is no change at flash status value.
I executed this esptool command:
C:\Users\Bortot\AppData\Local\Arduino15\packages\esp32\tools\esptool_py\2.6.1/esptool.exe -p COM175 -b 115200 write_flash_status --bytes 2 --non-volatile 0x0200
Can you help-me to understand why it not working ?
The ESP32 , esptool , cable, ftdi interface, strap pins, power, power capacitance are ok, because the comands [ read flash ], [ erase flash ] and [ write flash ] are working fine and showed below.
