Hi everyone,

I’m working on a mx21ads like board and have ported u-boot-1.1.4 to it.

When I boot my linux 2.4.20 on it, it seems not working so better. The messages are as below 1.

Firstly, I think my initialize is not complete, but the older bootloader run in my u-boot

Without initialize (I recommend all code, just remain the boot kernel code) can boot the

Same linux kernel yet! The messages are as below 2.

So, what’s the problem?

Thanks

Joe
