How to set Virtual Memory Address for excalibur with mmu?

Altera_Forum · ‎12-07-2013

Hello everyone.

The NiosII MMU boot mechanism puzzle me for several days.

With MMU,elf can be converted to the hex with virtual address by adding the mmu module.but I use the command elf2hex with this error:


$ elf2hex --input=nios2_germs_monitor.elf --base=0xd0004000 --end
=0xd0004800 --width=32 --output=memory_monitor_.hex
Exception in thread "main" java.lang.IllegalArgumentException: Data base address
 must be positive

Could anyone give me some clue?

Kinder Regards!

I got it by using the same elf2hex command in new version Qt instead of old one(5.1).
