install debian on 5big2 but no automatic boot

Hi,
I install debian jessie on a 5big2:
- partition 1 logical
- partition 2 raid
- partition 5 swap
- partition 6 boot
- partition 7 root
I create a special variable called diskload with this value "ext2load ide 1:6 0x800000 /uImage ; ext2load ide 1:6 0x1200000 /uInitrd ; bootm 0x800000 0x1200000" in u-boot and I save it.
When my Lacie boots, it doesn't find the good boot. So I break the LUMP search with <ctrl><c> and I write "run diskload". After that, the Lacie boots in linux.
I can't change the value of bootcmd in u-boot. What can I do to load my linux kernel automatically?
Thanks a lot.
Sincerely
