Subject: Ubifs issues on Samsung Nand versus Micron
Date: Fri, 12 Aug 2011 19:50:45 +0000	[thread overview]
Message-ID: <4E458415.7040005@vaaraahi.com> (raw)

Hi

Using Samsung Manufacturer ID: 0xec, Chip ID: 0xda (Samsung NAND 256MiB
3,3V 8-bit), on at91sam9263 board, with Arm-linux.

Getting the following errors intermittently:-


UBI error: ubi_io_read: error -74 (ECC error) while reading 129024 bytes
from PEB 517:2048, read 129024 bytes
usb 1-1: new full speed USB device number 2 using at91_ohci
UBIFS: recovery needed

UBIFS error (pid 1): ubifs_recover_leb: LEB 225 scanning failed
VFS: Cannot open root device "ubi0:root" or unknown-block(0,0)

Same issue when on kernel 2.6.30 and also on "commit
d6c9836c1114242aa89ea228bb1c43c17752b76c" of  ubifs-2.6.

I don't have the said problem with Mircon Nand.

Please help to find a solution to this issue. Is it the nand driver
which is the culprit?

warm regards

Nataraj
