Hi,

AM335x UBIFS will change to read-only when run almost 1 year. We are using Linux Kernel 3.2.

Do you know if new SDK solve this issue?

Hello Chen,

Check this link www.linux-mtd.infradead.org/.../ubifs.html
Could you provide UBIFS-related dmesg messages in order to determine what issue is this?

Best regards,
Kemal

Hi, Kemal,

Please see log below:

[ 7.751868] UBI error: ubi_io_read: error -74 (ECC error) while reading 64 bytes from PEB 177:0, read 64 bytes

If some of the data in NAND get corrupted over a period of time they lead to this uncorrectable ECC error. It doesn't seem related to the SDK for me but you can test one of the newer SDKs if this won't cost you a big effort.
You can download the latest SDK from here.
