Please allow jtag or jtag over usb on next version

@thrasher The M5Stack is aimed at the beginners market and so JTAG is not required, Debug over usb or uart is all we need. JTAG is also a dying standard and getting dropped from alot of hardware. its only certain categories of hardware designers who make use of it now, basically enterprise companies.

@thrasher Raw micropython is available as standered as UIFlow is built on it. REPL is also available over USB.
You can also Used VSCode and Xcode on OSX to program the M5Stack.
@lukasmaximus89 made a good video on VScode on youtube.

@thrasher I struggle to see how your webserver on ap question is in anyway related to jtag. I did already give you quite a lot of pointers to how to make a webserver on the M5Stack AP, please keep that to your other discussion instead of going off topic here.

Thanks, I've deleted all my posts, so if you have enough privelegies on this forum you can purge them -
@ajb2k3 Are you saying that m5stack has built-in full-fledged debug server that lets you put breakpoints and examine any variables or are you talking about debugging with printf? Because when I was looking for the infro on the first I couldn't find anything.

@ajb2k3 Of course we are talking about two different levels of debugging.
The BBC micro is also for beginners but allows both.

I've spotted this interesting article https://www.cnx-software.com/2020/02/12/esp32-jtag-debugging-microsd-card-socket/
But haven't tried it yet

@ajb2k3 But is it possible to debug (put breakpoints, show variables, callstack...) through USB or UART ? How ? Works with VSCode/PlatformIO ?

If your asking about REPL then yes it works with VSCode

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.”
