Hello all,
triggered by the e-mail below (which solved my issue, thanks Kim) I have the following question:
For how long can I expect current u-boot (say 1.3.4) to be forward compatible with newer Linux kernels?
It seems the u-boot from only half a year old cannot boot a current Linux kernel (!).
I typically work on products where the initial boot loader is adapted to provide fail-safe upgrades and itself is never upgraded to prevent the chance of non-flashable (bricked) products in the very small chance something goes wrong during the boot loader update.
How do people deal with using u-boot in a fail-safe environment where the chance of brickage must be zero and the (initial) bootloader itself cannot be updated? Should I plan for a second stage loader?
Also, is there any plan to add fail-safe features to u-boot?
Regards,
Leon.

I have tried to run the vanilla upstream 2.6.25.4 kernel on my U-Boot 1.3.0-rc2 (Nov 19 2007 - 16:37:36) MPC83XX
Is this u-boot too old, i.e. might there be a compatibility issue
yes start by updating u-boot
