CC and JTAG with other devices in the scan chain | Code-Composer

Technical discussions about Code Composer Studio.

The JTAG port is used both for debugging software in development and for boundary scan hardware test in production. Most of the PLD vendors provide support in their programming software for other devices in the scan chain. But I have received mixed advice on putting TI DSPs in a scan chain with other devices. TI has lots of literature saying you can do this and Code Composer seems to offer support for this. But when I asked TI support about it, they said they don't advise you to try it, but to put the DSP on its own JTAG port with no other devices. Seems TI can't make up its mind about whether or not they wish to support JTAG for boundary scan. Anyone have any experience with this? Have you used TI DSPs in a scan chain with other devices such as FPGAs and MCUs?
