SMT6001 uses the JTAG chain for the DSPs. If there are different DSPs in the system the daisy-chain is broken because C64xx, C67xx, use different drivers. But, you are still able to use SMT6001 without modifying your system if you do different setup in the CCS manager. In the configuration of the DSP chain, you have to BYPASS the processors which are not supported by the drivers. Refer to the help file of TI CCS setup manager tools section “Using Bypass in Your Configuration”. For instance, the number of bits to bypass are 8 for C620x/670x, 46 for C671x/621x and, 38 for the C64xx.
