I'm not sure what's going on here, but I appear to be having a reset 
problem with the Keil development board.

I am using CrossWorks for the ARM and a Olimex Parallel JTAG adapter, or 
a USB CrossConnect (both exhibit the same problem).

On initial powerup, download of code and debug the code runs as expected 
(some interrupt code and a counter to indicate that the interrupt is 
being run).

If I recompile (with or without change, it doesn't matter) and reload it 
then sometimes the code won't work. Or will partially work (eg. running 
in the main loop flashing LEDS ok, but the irq isn't executed -- counter 
is at 0).

I've tried various combinations of stopping and reloading, software 
reset of jtag adapter, etc. Pushing the reset button on the board, etc. 
The only thing that consistently works is pulling power from the board 
before reloading. If I have to do that every time I change the code I'm 
going to go nuts.

Has anyone seen this before? Or has any ideas?

Thanks,

Brian
