I am running into errors after creating a UBI filesystems on our NAND device. Can anyone suggest where I might look for the error?
A summary is included below and complete debug logs can be seen at https://gist.github.com/263e422eefa1401db68565fa3e4149bd After reset, the low-level `nand` commands work well. However if I format the partition for UBI with `ubi part`, the low-level `nand` calls start to fail. Calling `ubi part` again results in tons of ECC errors. I've confirmed that this sequence of commands works without error on a similar board with a different nand chip. The Cypress S34MS04G2 nand chip and is identified as a "AMD/Spansion S34MS04G2" under Linux. The SOC is an LS1046A which has an embedded freescale flash controller. Thank you in advance for any advice. => na nd erase.part nand_uboot Erasing at 0xfe0000 -- 100% complete.
