Hi,
When running the mtd_subpagetest I'm seeing more or less spurious ECC
corrections. I.e., one round may show 4 corrections and the next will
show 7, only some of which are the same as the previous 4.
Are the ECC errors expected to be that volatile and frequent?
I've seen various discussions regarding the OMAP sub page support, as
well as problems with the GPMC prefetch engine. Disabling both made no
difference regarding this. I've also tried two different sets of NAND
timings (relaxed and optimized), with no difference.
I'm using a Micron NAND that requires 4-bit ECC correction but I'm
running with only 1-bit (software) ECC. This is on an old kernel, 2.6.32.
Thanks,
Orjan
