Hi All,
I am using XDS560 PCI emulator inorder to debug the DSP code running on DM642.
By using Parallel Debug Manager I was able to connect the DSP Board which
consists of four DM642's and after that i was able to load my DSP.out file
into each DM642 Processor. But While running the dsp code i am facing the
following error
Error:
Error 0x00000022/-1154
Error during: Memory, Execution,
The memory at 0x01BC0000 continually indicated it was 'not ready'
The emulator was unable to regain control of the processor.
The processor must be reset.
Then immedaitely the system was rebooted because the watchdog timer was
expired.
Any suggestions regarding this will be appreciated.
Thanks and Reagards
Venki

I assume that your board design allows the JTAG chain to be "shorted" to just one DSP, using zero-ohm Rs. Configure
your chain for just one DSP, then run CCS + Parallel Debug Manager again for one DSP, and verify all functions are
working (code download, code run, memory tests, etc).
It can be difficult to separate hardware vs. software issues in multi-DSP JTAG chain situations. It's crucial to
design the hardware so any DSP in the JTAG chain can be bypassed using zero-ohm Rs, creating a shorter chain.

don't you have a jumper to inhibit the Watch Dog.
If you take control over the DSP via JTAG you cannot any more be real time,
DSP is halted, so it cannot refresh the watch dog, and then it resets.
If
you are in this case, usually designs provide a jumper to prevent the watch dog
to reset the board in case of debugging.

My suggestion...
When debugging, kill the code that enables the watchdog.
Perhaps by incorporating a Conditional Compile switch the causes the watchdog enable code to not be
produced.
Regarding "memory at 0x01BC0000"
Is that memory area mapped by your linker command file?
Is that memory area even in existence?
I would suspect a 'wild' pointer that needs correction.
suggestion:
--don't enable the watchdog while debugging
--put a breakpoint in the exception handler that is catching the problem.
When the code reaches the breakpoint, check all the register values AND the stack area to determine
in what function the error occurred and what instruction performed the error, that go to the source
code at that instruction address and debug the problem.

Richard,
you're right, this address looks like a peripheral register address that has been put into the address map.
try to see the map of the emulator...and paste it
