[U-Boot-Users] Bad Magic Number

[James Bates]

Hi All,

I have ported uBoot to our adapted version of the MPC8260ADS board. I just
changed the MPC8260ADS board config to suit our needs. The problem that I am
having is that any with image that I try to boot ( Yes I have used mkimage)
I just get "Bad Magic Number". I cannot think of anything else to try. I
cannot get it to recognise any images produced by mkimage at all. I have
tried most versions from 0.4.0 through 0.4.7 and all produce the same
result.

What could I be doing wrong?

Regards,

James Bates

Do the image files you created really contain the magic number in the
first 4 bytes?  You can check that fact like this:

[dzu]$ dd if=/tftpboot/uImage bs=4 count=1 | od -t x1
1+0 records in
1+0 records out
0000000 27 05 19 56
0000004

A bit useless on a public mailing list....

[U-Boot-Users] Bad Magic Number

Hi;

I'm a new user of ARM Versatile Board and U-Boot software.
Previously, milo.axf and linux kernel was stored in the flash.
I use milo.axf to boot the Linux Kernel image and it works fine.

After I write the u-boot image onto the flash (comes with the Vertatile CD from ARM).
The version is U-Boot 1.1.2 (Feb  4 2005 - 11:04:56). 

When I tried to use "bootm 0x34100000" (the linux kernel image address).
It gave me the "Bad Magic Number".

Could anyone tell me what was wrong ?

Thanks in advance.

You did not read the documentation.

U-Boot requires that you create a  special  kernel  image  using  the
mkimage tool.

Then please be a bit more careful when reporting problems.

How exactly did you write the linux image to 0xff010000 ?  And  which
sort of memory is mapped at this address on your system?
