Minimig build for DE2 not working   Message List  
Reply | Forward Message #9 of 327 |
Hi,

I've run the .sof Tobias has distributed with no problems.

However, when I try to run my own build (Quartus v7.2) the system
perpetually shows "loading kickstart" and then appears to reboot. Sometimes
it selects OSD menu options automatically - for example selecting "load df0"
and then shows the directory on the SD card - as if keys were being pressed
on the PS2 keyboard... does this with and without a PS2 keyboard plugged in.
And as I said, loading the pre-built SOF doesn't have these problems...

The *only* change I made was the path for the init_file parameter in the
hostrom.vhd file. I'm using the .hex distributed - I didn't build my own.

I also notice it complains about a missing minimig/bootrom.v file during
analysis, but still builds OK. I'm assuming this is Dennis' original bootrom
and not actually used? Also what about spihost/bigrom?

Any ideas?

Regards,
