I am using DSP56F801 EVM board. Further i am using an evaluation version of Code Warrior 8.2.3. The EVM was working fine but all of a suddent I am not able to download the code onto the EVM board. I get the following error "CCS protocol Plugin: Unknown Protocol error". I think the JTAG IC could be spoilt. Is there a way to test if the JTAG on the EVM works properly. I would also like to know if there is any application to test the DSP56801 EVM board as a whole.
