I'm trying to retrieve a U-Boot multi-image from a Linux MTD flash partition. I'm not sure, without knowing the file size of the image there, how to make sure I retrieve the image alone and not the entire partition. My U-Boot question is - Is there a way I can extract _just_ the data size from the U-Boot wrapper header info? i.e., make[2]: Leaving directory `/home/tomg/eldk/eldk-sbs/0.2/work/linux/linuxsbs-2.4.20/arch/ppc/boot/images' ./utils/mkimage.wrapper -A ppc -O linux -T multi -C gzip -a 00000000 -e 00000000 \ -n 'Linux-2.4.20 w/ ramdisk' \ -d images/vmlinux.gz:images/ramdisk.image.gz images/vmlinux.initrd.UBoot Image Name: Linux-2.4.20 w/ ramdisk Created: Tue Feb 17 15:33:45 2004 Image Type: PowerPC Linux Multi-File Image (gzip compressed) Data Size: 4524955 Bytes = 4418.90 kB = 4.32 MB Load Address: 0x00000000 Entry Point: 0x00000000 Contents: Image 0: 823267 Bytes = 803 kB = 0 MB Image 1: 3701675 Bytes = 3614 kB = 3 MB I'm thinking of some operations using "dd" to seek and copy the data size to a file or something. If this is not possible, I will quickly try and write a Linux NVRAM driver for U-Boot environmentals so that I can set a variable to retain the file image size. Any ideas are greatly appreciated. -- Tom G. ------------------------------------------------------- SF.Net is sponsored by: Speed Start Your Linux Apps Now.
