[U-Boot-Users] Uncompressing Kernel Image ... Error: inflate() returned -3

[Christian Darnell]

Hi All.

We are working with the development KIT from Atmel AT91RM9200DK
and have problem when the U-Boot tries to uncompress the kernel
Image.

We have done the following steps. 

We started to configure the kernel with menuconfig
and after that we run make dep and that was OK, then we performed
the following sequence.

1. make Image
2. /usr/local/arm/2.95.3/bin/arm-linux-objcopy -O binary -S vmlinux
linux.bin
3. gzip -v9 linux.bin
4. mkimage -A arm -O linux -C gzip -a 0x21000000 -e 0x21000000 -d
linux.bin.gz uImage

Version of the programs.
[root at localhost linux-2.4.19-rmk7]#
/usr/local/arm/2.95.3/bin/arm-linux-objcopy -V
GNU objcopy 2.11.2

[root at localhost linux-2.4.19-rmk7]# gzip -V
gzip 1.3.3

mkimage version: 0.3.0-1
