Hi,
I have a two-processor dev board which I am debugging
through an XDS510PP Plus JTAG emulator pod. I have designed my interface
hardware exactly as on page B-13 of the C54x Reference set, vol. 1. It is
sometimes possible to debug the two 'C5402s successfully, but I am
regularly getting errors, due to the processor timing out. This mainly
seems to be a result of using breakpoints, and single stepping. It also
has difficulty halting the processor. I am therefore assuming
that the problem lies with the EMU0/1 signals. These problems
mainly occur with the 1st device in the scan chain. Has anyone
had any experience with multi-processor debugging...can you recommend a
particular logic buffer? I am a bit worried that mine may be too slow.
Thanks in advance,
