mount jffs2 error

you'd better try them one by one.

try cfi first, and disable epcs.

the de2 has 4M cfi for later shippment. the de2_net has 1M cfi only. you need to update it in sopc builder and regenerate sof . you may see the thread of jay_1025, he had cfi jffs2 worked.

I have updated the sopcbuilder to 4M cfi and regenerated it , and how can I change the files altera.c and epcs_maps.c .Thanks !!

In Sopc Builder the cfi_flash_0 base:0x00000000 end 0x00300000

sdram base:0x00800000 end 0x00FFFFFFF

epca_controller base :0x00480800

THANKS

edit altera.c

static struct mtd_partition alteramap_partitions[] = {

{

.name = "romfs/jffs2",

.size = 0x400000,

.offset = 0x000000,

}

};

Rebuild kernel image from the start "make clean", "make linux_hwselect...."....
