If you have a TI emulator, open a DOS prompt in the ti/cc/bin directory and
run the program xdsprobe.exe with the -i option. Use 'xdsprobe -hv >
xdsprobe.txt' to generate a brief manual on xdsprobe. If you have another
brand of emulator, let me know. xdsprobe will verify the integrity of your
scan chain - I am not sure if that is your problem.
Can the host download to the "problem DSP" successfully?? If so,
you can download a few byte program consistinng of "branch to self + nops" and
issue a DSPINT. If you do this successfully, CCS should come
BTW, what are the types of the DSP??
I am debugging a board with 4 DSPs that are in a
JTAG loop. One of
the 4 DSPs is HOST which can access the other 3 slaves
HPI. But one of the slaves doesn't work well,ie, can't get
CCS if it is in the JTAG loop. Can anyone give me any hints?
