Hi Artem & Brian: > In order to implement the NAND boot for some Freescale's chips, such as > imx23/imx28/imx50/imx6, we use a tool (called kobs-ng) to burn the uboot > and some metadata to nand chip. And the ROM code will use the metadata to > configrate the BCH, and to find the uboot. > > The ECC information(ecc step size, ecc strength) which is used to configrate > the BCH is part of the metadata. The kobs-ng can gets the ecc strength from > the sys node /sys/*/mtdX/ecc_strength now.
