Honored Contributorwhat's this problem when starting linux?
what does it mean by wrong zone alignment? i have a 1M sram to run it, it's not enough?

Altera_ForumHi bigmagic,
> i have a 1M sram to run it, it's not enough? Probably not. I have a few bare bones images (no network support, few features) an even they have around 900 KB footprint. Regards, --Scott- Altera_Forum
hehe, thank u very much, scott. i will try it on another board with a larger sdram.

Hi!
I've found the same problem! The difference is that I have 2 Mb of RAM, and there's free space, as it shows the init of linux:
Mi complete init is:Memory available: 292k/2048k RAM, 0k/0k ROM (1404k kernel code, 292k data)
After that, it repeats enledssly the section:Linux version 2.6.11-uc0 (abg@INDES_ABG) (gcc version 3.4.1 (Altera Nios II 5.0 b73))# 16 Fri Jul 7 11:51:48 2006 uClinux/Nios II Altera Nios II support (C) 2004 Microtronix Datacom Ltd.

I thought that 2 MB was enough, so I don't think the RAM size is the problem... any idea?

it is out of memory.
you should have at least 8M sdram to run some apps on uclinux.
