Read/Write NAND OTP (AM335x + Linux 3.12)?

Dav01

Anyone here that know how to utilise the OTP areas of Micron NAND Flash under Linux 3.12/13+ ?

On most Micron NAND's you get thirty full pages (2112 bytes per page) of OTP data where the entire range is guaranteed to be good.

Doing it bare-bones would be straight forward, but questions is how to make it roll under Linux?

Thanks /David

Hi David,

I think it would be more suitable if you ask your question in the linux MTD development mailing list: http://www.linux-mtd.infradead.org/mail.html or search the archive.

Best regards,
Miroslav

Checked this before but didn't really find anything production ready which was a bit surprising. I was thinking if TI planned this support for the eval-kits that uses NAND. It serves as a good alt. to the additional SPI-flashes sometimes used for factory configs.
