Hi, I'm trying to use YAFFS on my project,I've downloaded YAFFS code from CVS and patched kernel to enable YAFFS support. Now, I can use flash_erassall in MTD tools to erase partition ,copy files into that partition and boot as root filesystem. The problem I encountered was I can't create image with mkyaffsimage/mkyaffs2image, the procedure is: on PC 1. mount a ext2 image we used as root filesystem before to directory WORK/ 2. mkyaffsimage WORK root.yaffs (mkyaffs2image 1 WORK root.yaffs) on target 3. flash_eraseall /dev/mtd5 4. nandwrite -a -o /dev/mtd5 root.yaffs I can mount this partition but all I get is a lost+found directory with something inside. My target system is Linux-2.6.11,AMD au1200 with Infineon 64MB nand flash. Is there anything I do wrong ? I've checked the mail list archive but can't get anything helpful, please give me a direction. Thanks for you help. Best regards, Will
