yesterday i use uboot 1.3.4, and found printf() crash.
i think it's a reason of GCC, so i port to uboot1.1.6.
when not using nand, it operate everything OK.
but when i add nand driver, it will run to nand_scan()->
if (busw != (this->options & NAND_BUSWIDTH_16)) {
printk (KERN_INFO "NAND device: Manufacturer ID:"
" 0x%02x, Chip ID: 0x%02x (%s %s)\n", nand_maf_id, nand_dev_id,
nand_manuf_ids[i].name , mtd->name);
printk (KERN_WARNING
"NAND bus width %d instead %d bit\n",
(this->options & NAND_BUSWIDTH_16) ? 16 : 8,
busw ? 16 : 8);
this->select_chip(mtd, -1);
return 1;
}
and printk crash, the same phenomenon as uboot1.3.4.
I try to disable nand controller,and the result remain the same.
So ,anyone can tell me where is the BUG on DM355? Or I haven't set the right register?
