what does it mean by wrong zone alignment? i have a 1M sram to run it, it's not enough?

Hi 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

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:  Memory available: 292k/2048k RAM, 0k/0k ROM (1404k kernel code, 292k data)   Mi complete init is:  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.

it is out of memory. 

you should have at least 8M sdram to run some apps on uclinux.
