NIOS is stuck at alt_tick after reset

Started by Guy_FPGA January 27, 2009
Hello all,

I am working with Alter NIOS terasic DE3 board-

I've written a software for NIOS.  When I run it in debug mode it look
fine. When I press the on-board reset I can see in the IDE that it has
entered reset mode. when I press the resume button - the SW is stuck.
If I press the pause I see that the SW is stuck in a loop insited
alt_tick.c --> void alt_tick(void)...

Does anyone know what is the source of the alt tick? how comes that it
works fine on first run and then stuck?

thanks alot,


Guy

Have you tried use flash for NIOS program ? Adam
Hi Adam...

I am not using flash for the nios program- all the SW is located at an
internal ram....

So you have to only update mif files thru compilation :) Adam
