I don't see how this would work on multiple blocks. I.e I have block2 as cramfs (root), and block3 jffs2 (W/R data). Can the input file be multiple blocks (2 & 3)? > If you have image files of the the two filesystems thewn you can > concatenate them just with cat (cat image1 image2 > combinedimage), > but this might not lead to the right spacing on the chip (it assumes > no gap between the two images which probably isn't the case) > > Wookey
