nios2-download error with MMU

Question

Hi,

I work on the nios2 kit 2C35. I would like to switch on linux with MMU after a µClinux Evalution.

I have met a problem during the flash programming. ("nios2-download -g linux.initramfs.gz").

I have an error during the verification.

"Verify failed between address 0xD0000000 and 0xD000FFFF".

It can't be a pinmap problem, I had the same during my evaluation of µClinux solution and when I use nios2-flash-programmer --debug, I can see my CFI Flash Table

Have you got an idea to explain my problem?

the address 0xD0000000 and 0xD000FFFF is wrong try to change address to 0x0000000 and 0x0000FFFF in custom_fpga.h

You must use the (new) option '--mmu' in order to make nios2-flash-programmer correctly working with MMU cpu.

Hi,  I have the same problem.  About the --mmu option, I've found it in nios2-programmer, but not in nios2-download at least in the version 9.0.

I don't think an option '--mmu' would be useful to 'nios2-download': the elf itself contains its loading address, which must be offset-ed with 0xc0000000 if I'm not wrong...

Does it solve your pb?
