Honored ContributorHi Wentao, thanks again,
I tried your suggestions, and I get a 'page allocation failure' on boot. I've pasted the boot output below. Currently, I'm setting PAGE_OFFSET to 0 and zones_size[ZONE_DMA] to 64M >> PAGE_SHIFT. Also, zones_size[ZONE_NORMAL] is being set to (end_mem - PAGE_OFFSET)>>PAGE_SHIFT. Is this correct? Thanks in advance, Ryan uClinux/Nios II Altera Nios II support © 2004 Microtronix Datacom Ltd.
