[U-Boot-Users] compatibility of uboot 1.1.1 with the linux 2.6.11.3 or linux 2.6.x kernels

[prafulla chandra vejendla]

Hi all ,
i am involved in building up the linux kernel on osk5912 board. for that i
am using the linux 2.6.11.3 kernel with the             u boot 1.1.1. once i
flashed into the kernal to memory i am getting the crc check error as bad
crc check  why is it so ??  i am suspecting that whether the uboot
1.1.1compatibility with the linux
2.6.11.3
thanks in advance

Did you call "saveenv"? You will always get the crc check error, if you 
don't save your environment.

[U-Boot-Users] compatibility of uboot 1.1.1 with the linux 2.6.11.3 or linux 2.6.x kernels

[prafulla chandra vejendla]

Hi,
i havent changed any environment variable before and after the download to
save the environment . before that i set the ipaddress and ethernet attress
and serverip parameters i saved those variables before itself.
my doubt is* can i use the same uboot 1.1.1 for any kernal i.e for linux
2.4.x or for linux 2.6.x* .is that version is compatible .*in the omap ti
page they mentioned if u are using linux2.6.x then u should use uboot 1.1.2.
*
*why is it so *.
what would be the* problem if i use inbuilt uboot 1.1.1 for my board for
linux2.6.x??*
* is that error " bad crc error "  due to that only ?? or due to any other
factor* .
please let me know ...
thanks in advance

Normally you can. There is nothing in  U-Boot  which  would  make  it
specifically dependent on a kernel version; on contrary, we try to be
as generic as possible.

We don't know this kernel tree ... Ask the guys who wrote such a
comment.

We don't know your kernel tree or what it expects.

On the other hand, I've been  using  old  versions  of  U-Boot  (like
0.4.0) with 2.6 kernels without any problems.

We could be more helpful if you provided  more  information,  like  a
*comple*  log  of  your  comands and all output. I speculate that you
don't use a correct U-Boot image at al. What exact command do you use
to build the kernel image, and what are the  last  20...30  lines  of
output of this command?

[U-Boot-Users] compatibility of uboot 1.1.1 with the linux 2.6.11.3 or linux 2.6.x kernels

[prafulla chandra vejendla]

Hi
linux 2.4.x or linux 2.6.x means the linux 2.4 kernel series such as linux
2.4.20,linux 2.4.21........... and so on similarly for linux 2.6.x means
linux 2.6.8 or linux 2.6.9,2.6.11 etc.............
here i am providing the steps i followed while building the kernel :-
*1) building tool chain*
                            # cd  /
                             #tar -xjvf /home/prafulla/arm-
linux-gcc-3.4.1.tar.bz2
                             #export PATH=/usr/local/arm/3.4.1/bin:$PATH
 *2)building kernel*
                             #cd usr/src
                             #tar -xjvf /home/guest/prafu/linux-
2.6.11.3.tar.bz2
                             #cp /home/guest/prafu/patch-
2.6.11-rc3-omap1.bz2  ./
                             #bunzip2 patch-2.6.11-rc3-omap1.bz2
                             #cd linux-2.6.11.3
                             #cat ../patch-2.6.11-omap1 | patch -p1
                             #make clean
                             #make omap-osk-5912-defconfig
                             #make menuconfig
                             #make
    #arm-linux-objcopy -O binary -R .note -R .comment -S
arch/arm/boot/compressed/vmlinux linux.bin
#gzip -9 linux.bin
#u-boot-1.1.1/tools/mkimage -A arm -O linux -T kernel -C gzip -a
0x10000000 -e 0x10000000 -n 'linux kernel image' -d linux.bin.gz uImage.cc
/
/
/
 once made this i have downloaded this image to the board by using the *kermit
protocol through hyperterminal* . and in uboot i used the command *loadb
0x10000000*
*here my bootargs are *
*console=ttyS0,115200n8 noinitrd rw ip=off root=/dev/mtdblock4 mem=30M *
afterthat i copied to the flash using cp.b 0x10000000 0x100000
memory location in flash .
and used *bootm 0x100000*
then afterthat i got the *bad crc error*
is this information is sufficient or if u want i can provide my
configuration details also .
is the configuration of kernel is dependent on u-boot. how it will effect ??
what is the effect of bootargs on kernel?? is there any relation between the
bootargs and the bad crc check error ??

Normally you should be able to just type "make uImage" here.

You are sure that 0x10000000 is the  correct  load  and  entry  point
addresses?

This CANNOT work. You cannot download the image to the  same  address
range where U-Boot is supposed to uncompress and copy the code to!

> and used *bootm 0x100000*
> then afterthat i got the *bad crc error*

I recommend that (1) you verify that your image on the host system is
OK by running "mkimage -l uImage.cc", and (2)  you  verify  that  the
downloaded image is still ok by running "iminfo".

Actually I would prefer if you had just copy & pasted the real  input
and output from your console.

U-Boot does not even attempt to start Linux so your bootargs settings
don;t play any role here.

[prafulla chandra vejendla]

thank you very much . i did mistake in the mkimage load address.
it should not be 0x10000000 i misunderstood this address with the
uncompressed image load address. once again thanks to Denk........
