I don't get you. If your JTAG is working, then you just download code via CCS. You don't use JTAG to load from a
Flash device; Flash connects directly to DSP EMIF, serial port, I2C, etc -- not to JTAG.
Please can you answer: 1) Do you have CCS? 2) Is your JTAG + CCS working? 3) What board are you using?
