Hi, I have created a yaffs2 image using: mkyaffs2image config config.yaffs2 And if use nandwrite and mount on partition I could see all the files properly. nandwrite -a -o /dev/mtd3 config.yaffs2 My probelm is, When I try to use the SAM-BA tool from ATMEL (AT91SAM9260 EK) to flash the yaffs2 image at the correct address of the partition, on mounting there would be no files except lost + found. So, I don't understand what's the problem. It seems, The flags -a -o for the nandwrite are really important to flash the image. This is not acheived by SAM-BA tool. If I just use nandwrite without flags, I get error #nandwrite /dev/mtd3 config.yaffs2 Input file is not page aligned Data did not fit into device, due to bad blocks : Success So, can any one suggest, How can I create page aligned yaffs2 image (which may be fine with SAMBA)? And, also Did any one try using SAMBA tool for yaffs2 images at all?? Waiting for HELP... Regards, Hari
