can't start CCS, 6713 DSK

Hi, 

I am a student working with a TMS320C6713DSK from TI. The dsk
functioned properly for a few weeks, during which I ran tutorial
programs and other simple projects on it. A few days ago, however, the
board suddenly starts to give me problems and I can't even start CCS
now.

If I boot my PC, connect to the DSK, then run the 6713Diagnostic
utility that came with CCS, all the general tests past. Now if I start
CCS, the window opens, about 10 seconds later I am forced to exit CCS
by this error message:

"Error 0x800000A0/-2090
Fatal Error during :Execution, Target Communication, Device Driver:
Timeout on Emulator or Target Proessor. It is....."

If I simply power cycle the dsk, then run the dianostic utility, it
fails at the Emulator diagnostics, or the DSP diagnostics. When I try
starting CCS, I get error such as

"Can't Initialize Target CPU: 
Error 0x00000200/-536866794
Error During: OCS
Unknown Error

I/O Port = 540

Board Name: C6713DSK
Cpu Name CPU_1
...."


Could someone give me some advices? I would really appreciate your
help. This is the first time I am working with a DSP and I am learning
quite slowly.

One possibility is that you tried to burn the flash memory with a new 
image and failed. It this case the DSP could run into a state where CCS 
can't access it. It can be other reasons as well. Try to press the reset 
button on the DSK and then quickly click on retry, this usually solves 
the problem.

Lars, thanks for you reply. I haven't actually burned anything into
the flash, but I still tried the reset followed by clicking on retry.
It didn't solve my problem... however I also found out on the yahoo
C6x discussion group that quite a number of people have the same
problem...

Are you using USB or a JTAG emulator? There is a utility to reset the 
emulator, this could help. Maybe it could be something with the 
configuration, are you sure it matches your DSP/DSK? I don't have any 
other ideas to solve it.

Hi Lars,

After trying really hard to remember what exactly I did before the
board broke.... I realized I was indeed experimenting with the
FlashBurn Utility Tutorial that came with the DSK -- now I've finally
learnt what is wrong with it!!!

When you mentioned 'reset' followed by 'retry', did you mean:
1. power cycle the DSK
2. start CCS
3. when the error message occurs, push 'reset' then click on 'retry'?

THANKS!!!

THANKS :-)

I am using the USB and embedded JTAG on the DSK. I have configured CCS
for dsk6713....
