Automated JTAG test procedure

[jeanthom]

An automated JTAG test procedure using an STM32 dev boards could be used for regression tests.

Trying now with another bluepill board as target device...

I have documented how to add another bluepill as JTAG target.

However, adding more manufacturers is still needed to detect "ARM Ltd" and "Thomson/SGS", they are not in the MANUACTURERS file.

I have tried to connect the bluepill to its JTAG pins, but the "detect" in urjtag gives a "TDO stuck at 1".

I've been playing with a spare CPLD board lately to test DirtyJTAG builds. It helped me to check whether basic JTAG pins were working on the newer targets.

I'd like to build a JTAG test jig around LambdaConcept's jtagtap and Gowin's cheap FPGAs that are supported by project Apicula. With a LiteScope onboard that would be a pretty rad test setup!
