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?

Also:

-please post to the group, not to me. I am not
the group

-please don't cut text from the thread. You
cut your original post, and I don't want to
go back to find it. When you cut text you
waste people's time and make it harder for
people to help you
