ESP32 Forum

I use the Annex+32 ToolKit V1.11 and a ESP-WROOM32 board with chip ESP32D0WDQ6 from manuafacturer 'ef' (Winbond). Reading Module Info (button) works fine. Flash Firmware Only (button) results in a "A fatal error occurred: Invalid head of packet (0x46)" message. I tried another board from manufacturer 'c8' (Gigadevice) with the same result. On my oscilloscoop I can see the EN and GPIO0 signals switching.
Who can help me out?

Hi,

Let me answer myself.

From https://sites.google.com/site/annexwifi/downloads I downloaded the wrong version 1.41. (ESP8266) After downloading version 1.38_RC5 (ESP32) all works fine.

Thanks for listening anyway!
