Hi
Does barebox use by default hardware ECC on nand flash ? I am on an
at91sam9263 board.
A previous mail by Sascha says that barebox uses hardware ecc while
u-boot uses software ecc by default.
After writing a ubifs using:-
"tftp rootfs.ubifs.nat /dev/ubi0.data " ,
I am able boot using a kernel that has MTD_NAND_ATMEL_ECC_SOFT,
but not with a kernel that has MTD_NAND_ATMEL_ECC_HW.
Am I missing something? Tried adding an ecc_mode in the following,
but in vain:-
static struct memory_platform_data ram_pdata = {
@@ -96,7 +96,12 @@ void at91_add_device_nand(struct atmel_nand_data *data)
if (!data)
return;
+/* Nataraj*************/
+
+ data->ecc_base = (void __iomem *)(AT91_BASE_SYS + AT91_ECC0);
+ data->ecc_mode = NAND_ECC_HW;
+/* Nataraj ************/
csa = at91_sys_read(AT91_MATRIX_EBI0CSA);
at91_sys_write(AT91_MATRIX_EBI0CSA, csa |
AT91_MATRIX_EBI0_CS3A_SMC_SMARTMEDIA);
May I have some help?
regards
Nataraj
