Hi,
I complie uboot-v2 (use pcm038_defconfig) for my own imx27 board.
My nand flash is sansung K9F1G08R0A 2k page 8 bit nand
loadb and tftp functions work well and uboot can boot up linux kernel
correctly
But I when I erased /dev/nan0.kernel.bb and reburn uImage
I got this error:
Hit any key to stop autoboot: 0
could not read: error -74
Does anybody know why?
BTW in nand flash driver I used
static struct nand_ecclayout nand_hw_eccoob_2k = {
.eccbytes = 36,
.eccpos = {
7, 8, 9, 10, 11, 12, 13, 14, 15,
23, 24, 25, 26, 27, 28, 29, 30, 31,
39, 40, 41, 42, 43, 44, 45, 46, 47,
55, 56, 57, 58, 59, 60, 61, 62, 63,
},
.oobfree = {
{2, 5},
{16, 7},
{32, 7},
{48, 7},
},
};
this->ecc.size = 512;
this->ecc.bytes = 9;
this->ecc.layout = &nand_hw_eccoob_2k;
When I programmed uImage and rootfs ,I reset the board uboot echos lots of
BADBLOCK.
