Hello,
For supporting optimized jtag chain length, you should look at CJTAG
specification, with star topology support.
CJTAG is not yet supported by openocd.

Hello Michel,
I had a look at the 1149.7 standard which seemed very promising at

There is already some smp support in there, you may want to have a look
at that. Using threads has been discussed, but I think the model would
break down with MMUs. That said for DSP's it could be a good model
if they don't have MMUs.
The OpenOCD
They indeed do not feature any MMUs, so threading seems like the logical
choice from a user's point of view.
OpenOCD now has RTOS threads support. That should offer a lot
of help and examples.
Perhaps you can even come up with some code-reuse or make
your multi-core MMU less DSP's behave like

Hi Sébastien,
Amontec is working on the SWD CTJTAG support on JTAGkey-3 generation.
Could you please let me know where did you get the info :
TMS is used as a clock while holding TCK at '1' really needs to be
added.
Best regards,

Hello,

With 1149.1, hardware is available on table for testing.
Openocd requires the introduction of a mode

For doing that, at every device change :

Hello everyone,
I am in the process of adding debugging support to one of my employer's
DSP. I came across OpenOCD and figured it would be a nice way of
interfacing the hardware with GDB, given the existing support of many
JTAG adapters.
The focus of my company is multi-core designs, which
