Timed out waiting for packet header

Hello all,

unfortunately I have the problem that I can’t get any programming on a newly purchased Lora32 V2 board.
All the advice I have already read here is unfortunately not getting me anywhere, as there is no complete documentation on the subject. At least not here in the forum.

Every time I try to load a program I get the error message:

A fatal error occurred: Failed to connect to ESP32: Timed out waiting for packet header

I have already tested the way described several times with RST and PRG button as well as bridging of pins. I have tested the whole thing on 3 different computers, with different hardware and different operating systems and also more than 10 USB cables.

It does not work. :expressionless:

Other ESP8266 modules and also Arduino UNO systems can be programmed without any problems.

I made a screenshot to show you that I have activated the boot mode, selected the correct board according to the documentation and I still try to upload only the Factory_Test_Wifi_LoRa32_V2.

Put the board into boot mode using the PRG button at startup

Does anyone have any ideas or have already been able to solve the problem?
Would be happy about constructive feedback.
