Hi Just wondering if the JTAG was exposed for chip on the the Teensy 4.0

Maybe some of the unmarked round pads on the back of the board?

Thanks

Not as published no. Paul did identify most of the rounds pads in one post - IIRC they were there for device factory testing of the numerous voltages and such critical to detecting the proper T4 function.

There was a note about a non-specific future idea potentially utilizing IIRC the bootloader CPU for debugging support in some fashion.
