Hello Simone,

There could be a dozen things wrong. Are you building this with the -e
option in the linker? If not, the PC (program counter) will not be set
properly after downloading your .out file and you will have to set the
PC to the start address manually.

Have you disabled interrupts in your program (INTM = 1, I believe, if
it's the same as the 54x)? If not, you could be getting spurious
interrupts (don't know what your interrupt lines are hooked to) and,
lacking a vector table, anything could happen.

Try this:

-Rebuild your project or make an incremental build
- click on "Debug" -> "Reset CPU"
- click on "Debug" -> "Restart"
- hit F5 (Run)

I hope this will help you. It seems that sometimes the DSP
resets itself or didn't want to start. Reset and restart
helped in my project.

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
