Hi Everyone:
We are developing on dm365 platform and program the nand flash with a programer.
The same kernel, when we use the programer with ECC algorithm "TI Read-Solomon(RS) ECC " ,we get the ECC flows:
ff ff ff ff ff ff d5 66
98 f6 da ae b4 8b 95 67
ff ff ff ff ff ff 36 a0
13 eb bd c8 0d e8 dd 6c
ff ff ff ff ff ff 96 e1
1d cc e5 3c ff 60 07 6f
ff ff ff ff ff ff e3 c4
79 ab 2d 41 8f d4 34 b9
when we use u-boot with ECC algorithm config "CONFIG_SYS_NAND_4BIT_HW_ECC_OOBFIRST",we get the ECC flows:
ff ff ff ff ff ff ff ff
ff ff ff ff ff ff ff ff
ff ff ff ff ff ff ff ff
d5 66 98 f6 da ae b4 8b
95 67 36 a0 13 eb bd c8
0d e8 dd 6c 96 e1 1d cc
e5 3c ff 60 07 6f e3 c4
79 ab 2d 41 8f d4 34 b9
The kernel programmed by u-boot run ok, but by programmer can not run。
we know there are to ECC algorithm configs from u-boot code as flows:
CONFIG_SYS_NAND_4BIT_HW_ECC_OOBFIRST
CONFIG_SYS_NAND_4BIT_HW_ECC
can anyone tell me the difference between this two configs and the " TI Read-Solomon(RS) ECC " ?
thanks !
