URGENT: JTAG error trying load a COFF file. - jcmarrupe - May 8 10:18:00 2004



Hi all,
I´m trying load a COFF file (.out) since PC using hpi, but an error
in Code Composer Studio is showed.
The error is "JTAG Communication error".

To load the COFF file I´m using 'dsk6xldr' application provided by
dsk 2.0 in 'C:\ti\examples\dsk6711\board_util\dsk6xldr' folder.

The contains of the configuration file (.cfg) I´m using is:
;CFG-2.0
;
[POD_DRVR] 'dsk6x11pp.dll'
[POD_MODE] 1
[POD_PORT] 0x378
;[POD_LOG_MAIN] 'pod_main.log'
;[POD_LOG_FUNCTION] 'pod_func.log'
;[POD_LOG_ADAPTER] 'pod_adapt.log'
;
;SCAN PATH
"cpu_a" TI320C6711

Which is the error?

Any help will be appreciated.

Thanks in advance.

Try it with CCS closed.  You do not need CCS for HPI and HPI does not use JTAG.
 
I am not sure what you are doing in CCS, but if it is open CCS uses the parallel port to communicate with the JTAG controller on the DSK while your program is using the parallel port to communicate with the HPI port on the DSP.  It sounds like at least one of them is getting 'confused'.
