CONFIG_PMECC_CAP has a higher priority than its ONFI detected parameter and will overwrite it when defined. As per commit 49ad40298cc5, CONFIG_PMECC_CAP has a default value of 2 if not otherwise stated. This results in the overwriting of the ONFI ECC bits value. The following errors are seen when booting the kernel from the nand flash:
Loading Environment from NAND... PMECC: Too many errors NAND read from offset 140000 failed -74 *** Warning - some problems detected reading environment; recovered successfully *** Warning - bad CRC, using default environment
In: serial Out: serial Err: serial Net: eth0: ethernet@f8008000 Hit any key to stop autoboot: 0
NAND read: device 0 offset 0x180000, size 0x80000 PMECC: Too many errors NAND read from offset 180000 failed -74 0 bytes read: ERROR
NAND read: device 0 offset 0x200000, size 0x600000 PMECC: Too many errors NAND read from offset 200000 failed -74 0 bytes read: ERROR Bad Linux ARM zImage magic!
Fix it by setting the right value for ECC bits.
