I have not tested JTAG support recently, so I can't offer much advice right now. If I were testing this again, I would try the following next steps: 1. Increase...

Sigrok supports a [fairly broad range](https://sigrok.org/wiki/Supported_hardware) of USB-based logic analyzers, but I understand if you don't want to add a software configuration problem on top of your hardware debugging problem....

I'm not too likely to add support for hardware control lines since I don't normally use them, though I can see the appeal of having GPIO that can be controlled...

Hi @UweBonnes, you might be looking under the "planned features" section, which would basically be updating it to CMSIS-DAP 2.0. I've considered updating the firmware since CMSIS-DAP 2.0 is more...

Hi @fanoush, I'm glad you've been successful in modifying it to your needs. Supporting STLink/v2 clones is something I started doing very early on in the project. There are some...

Hi @wamk9, dapboot implements the vanilla DFU protocol where the host just uploads or downloads a flat image to a fixed address. It looks like you're trying to use ST's...

It's theoretically possible, though I'm not sure that the JTAG throughput will be satisfactory - the CMSIS-DAP commands for JTAG are very close to just passing bit-banging commands over USB...

That seems reasonable, since RTCK should only ever be a delayed copy of JTCK.

The webstlink source was ported from [pystlink](https://github.com/pavelrevak/pystlink) before STM32L4 support was added. It looks like pystlink picked up support for it in 2019. Adding support to webstlink should be possible,...

Hi @ildar, I don't have a hardware design for the STM32F103 because the F103 variant of the firmware targets ST-Link/v2 clone hardware, which is mind-bogglingly affordable. You can either refer...
