MD5 mismatch on ESP32
Posted: Sat Oct 06, 2018 11:19 pm
Morning:
I got a circuit using ESP-wroom-32. From yesterday, when I attempts to upload the program, it tells me
The MD5 of flash stays the same every time.
I use Arduino IDE 1.8.5.
I tried erasing flash, it finished without any error reported, however, it is believed to not being erased as it should since erasing a working DevKit-C that i got, it make the DevKit-C resets rapidly. But wroom after erasing just shows user code done.
The only thing that could be wrong is yesterday when I was programming another chip(Atmel) which shares the Vdd rail, I have put 5v on Vdd - ESP32 has been taking 5v for around 2 minutes.
Most fuses are not burnt, as far as I know(I found out DevKit-C got CONSOLE_DEBUG_DISABLE burnt so I did the same on wroom).
Fuses and complete error will be listed below.
Any help will be appreciated.
Regards.
