Hi to all,
I've finished a design with a DSP56321, and i am now debugging the
hardware.
My approach is nothing original: i just copied from the DSP56321EVM
schematics the part between the processor and the PC's parallel port,
and wish to use SUITE56 to load a program into the dsp's memory. This
part consists only in a few line buffers/drivers and level matching.
So now i can reset the dsp, read registers' contents, and load a
program... But when i launch program execution, Suite56 shows the
message 'STOPPED AT DEBUG INSTRUCTION IN USER PROGRAM'. There
isn't
such an instruction in my code... And if i click several times
the 'NEXT' button, the dsp seems to execute the instructions, then i
get 'ERROR NEXTING' and 'ERROR READING MEMORY' (this happens
everytime when i click 'NEXT' for the 6th time).
I have checked the signals from the parallel port, and they look ok,
except DE which is always low.
Any idea of what's going wrong?
Also, i noticed that Suite56 works only with old PC hardware. Anyway
to have Suite56 working with a new computer?
Thanks a lot!
Gustave
