Jumpering the ESP-WROVER-KIT-VB for debug

With many, many thanks to @ maxgerhardt for his patience and help with my previous question, I can now debug, after a fashion.

However, it seems ot me that when I have jumpered to Enable JTAG functionality, PlatfomIO cannot upload my code:

The terminal process terminated with exit code: 1

If I power off the board, remove the JTAG jumps and reconnect, I can upload, but then I have to power off again to reattach the JTAG jumpers in order to be able to debug.

What am I doing wrongly?
