Hi Scott,
yes it's an ONFI flash, but the OOB size is 224 bytes, which results in a data abort (see below).
Apparently the supported ONFI detected OOB sizes are 8,16,64 and 128 bytes. I lack a nand_oob_224 struct but I don't know what the default positions would be.
What NAND driver are you using? Are you using hardware ECC or software ECC?
