Although the data area is protected for 8bit correction with BCH8 algorithm, the oob area is unprotected and is susceptible to bit flips These errors are very frequent and it results in jffs2 file system mounting problems and other related issues I also confirmed the problem through oobtest module. Can you please suggest any solutions/workaround Regards Vipin From mboxrd@z Thu Jan 1 00:00:00 1970 From: Vipin Kumar Date: Tue, 3 Jan 2012 15:06:12 +0530 Subject: [U-Boot] 4k page ONFI NAND Message-ID: <4F02CC0C.8020203@st.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de Hello, We have a Micron 4K page sized ONFI NAND MT29F16G08 I am encountering frequent errors while reading the device.
