very strange DSP problem

Started by Simone Winkler March 16, 2004
Hello!

I've got a small programm that lets a LED blink on my DSP. It's a
TMS320F2812 on a ezDSP F2812 board.
The program didn't seem to work until I once disconnected and reconnected
power supply. I also changed one jumper on the board to another position
(where the led is always on) and back to the position where the LED is
programmable by the XF-pin.
Then it suddenly worked and blinked.

Next time I tried, nothing worked anymore, and it was not possible to get it
working again. (neither by disconnecting and reconnecting power, restarting
code composer, etc.)

Do you have an idea what could be wrong?

I'm using code composer v2.12, programming via parallel cable, in the
cmd-file i set that the programm should only be written to the RAM but not
to the flash memory. Also the jumpers are set to H0-programming mode, as it
is done by default.

Can you help me????

Thank you for any suggestions!!!

Simone

Have you tried contacting the board's manufacturer? I would imagine that they have some sort of technical support. --a
