bootldr question : can not boot!
This question may be asked so many times here. But I meet a new question:)
I use 'load flash 0x0080000' command to download kernel 'zImage' to the third
partition of flash,
then I type boot in bootldr prompt.
It seems that it 's kernel to print garbage ,which I do not understand. But when I use
blob to test, my kernel
works well till login prompt (when start kernel, I switch minicom serial speed to
115200. ).
Can someone give me a hand ? thanks a lot !
here are auxiliary information:
