Wrong arch..

Hi!

On my Jornada 568, i have installed bootldr. With serial line/minicom, i can 
see that:

Compaq OHH BootLoader, Rev 2-20-4 [BIG_KERNEL] [MD5] [MONO]
Last link date: Thu Jul  3 10:43:47 EDT 2003


When i do a load root, uploading 
http://handhelds.org/~chicken/bootopie-v0.7.2-rc5_j56x.jffs2, i have "erase 
error", and the flashing does not work.

I have tried to change de bootldr, with "load bootldr", uploading 
http://handhelds.org/~chicken/bootldr-j56x-2.21.11.bin.

It says "wrong arch" with an arch serial number.

What is wrong?

Regards,

Gaetan.
