I am using Eclipse 2020-06. I have setup a template project which builds ok.
Then flashing as listed in https://github.com/espressif/idf-eclips ... e-site-url
With error:

Code: Select all

A fatal error occurred: Invalid head of packet (0x50)
Adding "flash"'s dependency "all" to list of commands with default set of options.
Executing action: all (aliases: build)
Running ninja in directory c:\users\kevin\eclipse-workspace\kg1_hello_world\build

esptool.py failed with exit code 2

Please see two attachments.
Any help much appreciated.

Im not eclipse user, so i dont know how to add it, but you have to add command to select target. With Cmake it is like that:

Code: Select all

idf.py set-target esp32s2

From the console output it seems that the launch-target is set to a ESP32 instead of a ESP32-S2.
To check and edit, in the top of your Eclipse window you can find the launch target edit-box: the rightmost one in this picture saying Firstmate:

If you have a launch configuration, click the settings-wheel, otherwise click the down arrow and create a new configuration.
In that window you can select the target and the serial port, the example shows the esp32 as target:

I am guessing that yours does also. If so select esp32s2 in the target select box.

Hopefully that does the trick.

Please select esp32s2 in the launch target window as shown by @jamawa
