[U-Boot-Users] U-boot 1.1.3 support Bzip2 compression?
Hi all,
My platform is OMAP5912osk. The setps I create the bzip2 kernel image are : ************************************************************ arm-linux-objcopy -O binary -R .note -R .comment -S arch/arm/boot/compressed/vmlinux linux.bin bzip2 linux.bin mkimage -A arm -O linux -T kernel -C bzip2 -a 0x10c08000 -e 0x10c08000 -n "2.6.15 " -d linux.bin.bz2 uImage ************************************************************ Then I put kernel image at 0x10000000.
According to the README of u-boot 1.1.3 : ---------------------------------------------------------------------------------------- - Compression support: CONFIG_BZIP2
If this option is set, support for bzip2 compressed images is included. If not, only uncompressed and gzip compressed images are supported.
NOTE: the bzip2 algorithm requires a lot of RAM, so the malloc area (as defined by CFG_MALLOC_LEN) should be at least 4MB. ---------------------------------------------------------------------------------------- In /u-boot-1.1.3/include/configs/omap5912osk.h, if I use the original config : #define CFG_MALLOC_LEN (CFG_ENV_SIZE + 128*1024) #define CONFIG_BZIP2 1
The result when u-boot decompress the image is : ************************************************************ ## Booting image at 10000000 ... Image Name: 2.6.15 Image Type: ARM Linux Kernel Image (bzip2 compressed) Data Size: 1159790 Bytes = 1.1 MB Load Address: 10c08000 Entry Point: 10c08000 Verifying Checksum ... OK Uncompressing Kernel Image ... BUNZIP2 ERROR -3 - must RESET board to recover ************************************************************ But I change the setting according to README : #define CFG_MALLOC_LEN (CFG_ENV_SIZE + 4224*1024) #define CONFIG_BZIP2 1
The result when u-boot decompress the image is still fail: ************************************************************ ## Booting image at 10000000 ... Image Name: 2.6.15 Image Type: ARM Linux Kernel Image (bzip2 compressed) Data Size: 1159790 Bytes = 1.1 MB Load Address: 10c08000 Entry Point: 10c08000 Verifying Checksum ...

Any one has any suggestion on how to solve this ? Anything wrong in my modification ???
Thanks for your patience~

Thanks.
But the result is the same :

## Checking Image at 10000000 ... Image Name: 2.6.15 Image Type: ARM Linux Kernel Image (bzip2 compressed) Data Size: 1159790 Bytes = 1.1 MB Load Address: 10c08000
-------------------^^^^^^^^

-------^^^^^^^^^^^^
What's your memory map?
Where exactly is your TEXT_BASE, and where is stack and the malloc arena?
The PC at the time of the crash was 0x1108fc88, so TEXT_BASE is somewhat lower. You wrote that you have CFG_MALLOC_LEN defined to be somewhat greater than 4224*1024 = 4.125 MB. The malloc arena is located below TEXT_BASE, so at least the area starting at
0x1108fc88 - 4224*1024 = 0x10c6fc88
is in use by U-Boot.
You uncompress the image to 0x10c08000 ==> BINGO! The areas overlap. When decompression starts, you start overwriting U-Boot data.
Try a lower image address.

Hi Denk,
Thanks for your reply....
The memory map and other configures are all kept default of omap5912osk in u-boot. I only change two items in /include/configs/omap5912osk.h : #define CFG_MALLOC_LEN (CFG_ENV_SIZE + 4224*1024) #define CONFIG_BZIP2 1
I try to lower the image address.... But it still fail :( ----------------------------------------------------------------------- U-Boot 1.1.4 (Aug 1 2006 - 07:40:21)

Any suggestion about this error ?
