I follow these steps: $ make zImage $ arm-linux-objcopy -S -O binary vmlinux linux $ gzip -vf9 linux $ mkimage -n name -A arm -O linux -T kernel -C gzip -a a0008000 -e a0008000 -d linux.gz linuxgz.image
then load it follow these steps: =>loadb 0xa1000000 =>bootm 0xa1000000 ## Booting image at a1000000 ... Image Name: akzhd crazy Image Type: ARM Linux Kernel Image (gzip compressed) Data Size: 791658 Bytes = 773.1 kB Load Address: a0008000 Entry Point: a0008000 Verifying Checksum ... OK Uncompressing Kernel Image ... Error: inflateInit2() returned -4 GUNZIP ERROR - must RESET board to recover
please help me, thanks.

Thanks for your help, But when I follow your step, after bootm, u-boot complain that :
=> loadb 0xa0008000 ## Ready for binary (kermit) download to 0xA0008000 at 115200 bps... ## Total Size = 0x000c14aa = 791722 Bytes ## Start Addr = 0xA0008000 => bootm 0xa0008000 ## Booting image at a0008000 ...

what should I do?
Fix your image. The addrress where it is stored in RAM (as used by " bootm 0xa0008000" must be different from the "Load Address: a0008000" and "Entry Point: a0008000" values, or it will overwerite itself when it gets uncompressed.
