* [U-Boot] U-Boot: Checksum error when booting kernel from jffs2 partition @ 2012-12-27 16:24 dpdonny 2012-12-27 18:58 ` dpdonny 2012-12-27 22:04 ` Dan Donahue 0 siblings, 2 replies; 3+ messages in thread From: dpdonny @ 2012-12-27 16:24 UTC (permalink / raw) To: u-boot Greetings, I am using U-Boot version 2011.09-00096 and Kernel 3.1.0 on a proprietary board booting out of NOR flash. The only mods to the sources are my BSP files. All is well as long as the kernel image and ram filesystem archive image are created with the mkfs.jffs2 command and copied into flash (in directory 'foo' for this case) from U-Boot using the 'cp' command. The U-boot environment file is updated to point to foo and the board successfully boots the kernel. No padding is used when creating the jffs2 image. Once the kernel is booted I create directory foo2 in the same partition as foo (again from the kernel). My update untars an archive containing the kernel image and ram filesystem into foo2, updates the U-Boot environment file to point to foo2, and reboots. U-Boot comes up, fsloads the images from foo2, and the Checksum error is seen. Note, If I create a jffs2 image containing both foo and foo2 the checksum error is not seen. Is there a jffs2 compatibility issue between my kernel and U-Boot? -- View this message in context: http://u-boot.10912.n7.nabble.com/U-Boot-Checksum-error-when-booting-kernel-from-jffs2-partition-tp143640.html Sent from the U-Boot mailing list archive at Nabble.com. ^ permalink raw reply [flat|nested] 3+ messages in thread

It looks like a hardware or kernel driver issue. Software timeouts are seen in the kernel CFI command set driver during the write. The driver reports the copy succeeded in spite of the timeout. I was able to do a copy without experiencing timeouts and the kernel booted just fine. I apologize if I've wasted anyone's time...I see several people took the time to read the post. --- Dan Donahue -- View this message in context: http://u-boot.10912.n7.nabble.com/U-Boot-Checksum-error-when-booting-kernel-from-jffs2-partition-tp143640p143651.html Sent from the U-Boot mailing list archive at Nabble.com. ^ permalink raw reply [flat|nested] 3+ messages in thread
