ESP32 - exit status 255

Other Hardware 3rd Party Boards
1

I am trying to compile and send code to a DFRobot ESP32-E V1.0 Firebeetle though I constantly get the exit status 255 error. It only occurs after I install Espressive 3.1.1 board drivers. It doesn't matter what code I try to upload from the examples - same result. Have done a clean IDE install - going crazy. Cant find any relevant info. Any help much appreciated!

Do you get a compile error or an upload error?
Which operating system are you using?
Which version of the IDE?

The easy solution would be to roll back the Espressif board package to the previous version that worked.

Note: it's not a driver; it's a board package.

Thanks for the suggestion - I tried going back to Espressive (board package) 2 and had the same problem. It is Windows 11 and IDE 2.3.4. It says Compile Error: exit status 255 - the error occurs quite quickly after pressing the compile (not upload) button. I can select the board and the port at the top of the screen and get the board ID.
I did a complete re-install of the IDE including manually removing all the libraries and support folders. Nothing obviously has worked so far.

Please enable verbose output during compilation under file → preferences in the IDE and compile a problematic sketch (preferably blink).

Copy the complete output here; use code tags when doing so using the <CODE/> button.

OK - I will do - thanks. (tomorrow as its on my work computer)

This is the code below - just one of the example files.

This is the verbose compile error as below:

The command prompt has been disabled by your administrator.

Press any key to continue . . . 
exit status 255

I see the verbose error message is saying the command prompt has been disabled by the admin... I guess it is local security issue then?!

I don't know. Are you the local administrator or is the a corporate laptop?

You can search for that error message on the web; solutions are provided but if you're not the administrator I don't think that they will work and you will need to contact the administrator.

I've moved your topic to a more suitable location on the forum as it's not an upload problem.

Thanks so much! Getting the verbose output was the key. Shoulda though about that. I will contact admin. Gotta say however, the non-verbose error message is not helpful and there seems to be no reference for these error messages. Thanks again for your help.
