Bump -
Now (last month) JTAG debugging went free on PlatformIO/Visual Studio Code and Andreas Spiess did a YouTube video on debugging with the Espressif ESP-prog board JTAG interface for the ESP-32.
First thing I did was check into M5Stack Core and found it wouldn't work.
Another version with IO12-15 available for JTAG inline debugging would be necessary and appreciated.
thank you

@ajb2k3 Of course we are talking about two different levels of debugging.

The BBC micro is also for beginners but allows both.

As always, GPIO 14 is already in use for the display.

“All the pins other then GPIO14 are availiable, however for some reason it was used for LCD CS on the M5Stack rendering JTAG unuseable.”
