3 years ago Hi @dylono96,
Can you please check your firmware image file? The size of 105472 bytes reported by the esptool does not seem correct. It should be 1444336 bytes.
Here is the esptool output when I erase and program an ESP32 board (WROOM module).
I hope this helps!

Hi, hope you can help me. I want to give the prebuilt flash a try, but it keeps giving me the following error:
I believe the flash address is wrong, but what can I do about this?
