That's normal since writing new data means writing a new error correcting code. > So when I try to reboot nothing is working because every program assumes that > the first blocks are bad. > Do you have a suggestion how to fix that issue? Not sure that I understand what "every program assumes..." means. But my guess is that the OOB layout may be different in nand_spl/nand_boot_fsl_nfc.c compared to drivers/mtd/nand/mxc_nd.c so the nand_spl may interpret the OOB information that mxc_nd.c has written in a different way. This is especially true for large page NAND since the i.MX31 controller uses a non-standard layout, for small page NAND there should be no problem (although I don't know if nand_spl has been tested on small page nand yet). /Magnus _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
