Microtronix uKIT FLASH Programming problem

Hi all,

I have made a NIOS I project for the Microtronix uKIT development board. All the hardware and software stuff is running but I have a big problem.

I am storing the fpga design dat in the epcs device and I want to start the software from FLASH (CFI for AM29LV640MH). But I cannot bring the software into the FLASH.

I use also the old toolchain:

nios-build (make) --> srec2flash --> nios-run *.flash

I can observe that the erasing of the FLASH sectors operates properly but when it starts to write something to the FLASH, the processor hangs up.

With a NIOS II design the FLASH programming of some test programs (e.g. mem_test) works properly.

I know, the uKIT was mainly developed for NIOS II but I have to make a system, that is more or less equal to some former designs. This former designes used NIOS I and since I wanted to use the software without major changes from the old design I decided to use the NIOS I here too.

Is there a known problem with NIOS I the CFI and the old GERMS monitor?

Is there any chance to put my software into the flash using a NIOS II - "PROGRAMMER" - system?

Looking forward for some replies...

Marco.
