List-Id: Linux MTD discussion mailing list List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Hi All, I am using Linux-2.6.10 with the lastest CVS MTD codes. My device is a Intel IXP E.V. board, configured as a big-endian machine, with 8M NOR flash and 32M NAND flash. I can mount a JFFS2 partition correctly without enabling the JFFS2 summary support. But, I usually got warning messages, when turn on the JFFS2 summary support. (I don't know this problem occurs unders what condition) The following steps are used to test: 1. flash_eraseall /dev/mtdblock/3 2. mount -t jffs2 /dev/mtdblock/3 /mnt 3. do some operations (mkdir, touch, dd, ...) 4. umount /mnt 5. mount -t jffs2 /dev/mtdblock/3 /mnt then the warning (error!?) meesage showed: JFFS2 warning: (86) jffs2_sum_process_sum_data: Unsupported node type found in summary! Exiting... mount: Mounting /dev/mtdblock/3 on /mnt failed: Input/output error I added some debug code and found the warrnig always occured with nodetype 02E0. This looks like a endian problem. Would someone help me to debug? Regards, Robert
