I have an ARM922T with u-boot 1.2.0 I created 1 image with mkimage. This image contains my kernel (zImage) and my ramdisk. mkimage -A arm -o linux -T multi -C none -a 0x8000 -e 0x8000 -n "Kernel-Ramdisk-Image" -d zImage:ramdisk.gz mImage
1) Flash mImage with uboot The kernel works nice.
2) Now I want to upgrade Flash image from Linux I use flashcp on my MTD partition. I successfully write the image. $ flashcp updateImage /dev/mtd1 When I reboot I have a bad CRC error in u-boot.
I made a dump of my MTD partition with dd and I compared it to mImage. I have seen thaht CRLF are replace by LF ! Why does u-boot remove CR ? How can I generate a correct image for flashcp ? Is there a special tool to generate an image for flashcp or is there another tool than flashcp to update my board ? How can I verify the image checksum ?
