Hi
Customer is working with custom board using VXWORKS
Description :
A nand flash – Micron is connected, and I try to use ECC in mode BCH8 with vxworks.
With Uboot it works fine, but I can't capture that in Uboot.
In vxworks It was set to hamming code by default.
I try to change to BCH8 and these are the registers values before I write to the nand :
GPMC_ECC_CTRL 0x1
GPMC_ECC_SIZE_CFG 0x3fcff000
GPMC_ECC_CFG 0x11031
This is what I write to the nand :
-> vxbNandFlashDump 0x80961a04,0,0,1,2

What is now written to the nand in psge 0 is the boot code, but the board is not running in this case.

OOB:
