ESP compile error

[MJU20]

I've been trying to flash this ESP32 WroverB module for a few days but I always get this error..

Code: Select all

ninja: no work to do.

esptool.py v2.9-dev
Serial port COM6
Connecting...

A fatal error occurred: Invalid head of packet (0x65)
I've changed the Flash size to 4Mbyte in idf.py menuconfig (the ESP is 4Mb), but I don't know what to try next...

In Arduino serial monitor I get this message after it boots:

What else can I do to get my Flowcode project onto the ESP32?

Hello,

From a bit of Googling it could be down to a faulty ESP32 device. Do you have another device you can try and use to double check. Do you have anything conected to the ESP that could be blocking the flash pins from working properly?

Thank you BenR,

Sorry for may late response but I didn't see the notification for the reply.

I found that there probably is a problem with some kind of Flash on the board.
Told the Chinese seller (via Alie..), and they paid me back the module.

Thanks again for your help!
