[FR] add JTAG support for STM32F103

Open ildar opened this issue 6 years ago • 4 comments

I successfully use dap42 on a general STM32F103 board (BluePill exactly). I guess nothing prevents JTAG be on for it. Thanks.

Hi, it is technically possible to add JTAG support, but I haven't spent much time integrating it because I usually don't need full JTAG and from the last time I looked into it, the performance was not great. This is in part because the USB handling is not particularly optimized, and in part because CMSIS-DAP 1.0 is not very fast as far as JTAG transports go.

I see your point. I suggest this FR stay opened, just hanging out. Thanks!
