Nios II IDE flash programmer problem?

Altera_Forum · ‎02-11-2005

Hello Nios experts,

I am using Nios II v1.1 with the IDE v1.1.0 and Quartus II v4.2. When I compile a simple project like the diagnostic or the hello world program, I can debug it fine. It generates a good elf file and a flash file. But when I go to use the flash programmer from within the IDE, I run into these problems. It claims that my flash file is too large for hte flash component. I don't think so, I tried these same simple projects with and older nios II v1.0.1 and Quartus v4.1 and it works fine. Here is the result form the console...

I don't know what the problem is...

Any help would be appreciated.

UPDATED: Problem fixed...

It turns out it was one of two things performed that corrected this problem.

1) Nios2 license expired, v1.1 required new license. After obtaining new license and rebuilt, the flash programmer worked fine.

2) The other change made was change the exception address in sopc builder to point from ext_sram to sdram, but I don't think this had much to do with it at all.

Those were the two changes made and the flash programmer works correctly now.

Wished there were some warnings or errors that would have helped get to this point sooner.
