Hi,
When using 'nandecc hw' on an OMAP3 platform, data is not being correctly written to NAND. I see the issue on 2013.10-rc2 and 2013.07 but not on 2012.10. Specifically, when I read back a SPL binary written with hardware Hamming ECC, I don't get a matching CRC. With the BCH8 ECC algorithm, the CRC is correct (but SPL must be written with Hamming otherwise the board doesn't boot)
I've shown my steps here: http://pastebin.com/tLZsr9zH The expected CRC is 46745188.
Any suggestions/ideas much appreciated!
I'd swear this worked when I changed the command to use BCH ... I'll check it again today.
Best regards
