Hi Rik,

This patch is for U-Boot only. You might wanna find the kernel patch at http://rocketboards.org/gitweb/?p=linux-socfpga.git;a=commit;h=23b95d8c25d34...

While for your issue, its quite strange. Currently, we are using 512 byte sector protected with 8 bit ECC. With this configuration, we will need around 58 bytes at OOB. This is to accommodate 2 bytes bad block market + 42 bytes data + 14 bytes ECC.

Wonder you are using different configuration? Thanks and have a nice day!

Chin,

I was wondering which kernel this patch went into or is going into?

I am having problems with accessing a hynix NAND from an altera cyclone V using kernel 3.11. It is coming up with a kernel driver error on boot of: "Your NAND chip OOB is not large enough to contain 8bit ECC correction codes"

Looking for help on this issue.

Cheers Rik
