TMS320VC5502: TMS320VC5502

Part Number: TMS320VC5502


I received a questions regarding communicating with the VC5502 via JTAG I am hoping to received help with. In specific, the questions is related to communicating with TMS320VC5502 DSP via JTAG.  The engineer has observed a failure to talk to the DSP using TI’s XDS200 JTAG emulator and Code Composer. The DSP is never found. The JTAG bus is not the issue because downstream of the DSP on the bus is a CPLD, which is programmable via JTAG. Eventually, the goal is to program external flash memory that is attached to the DSP using JTAG. The flash contains the DSP’s bootloader and application code.

May I get assistance with this issue?
