Why can't uncommpress kernel after download s-rec file via tftp?

[Dross Zhou]

Hello all,
I just added some config option in make menuconfig,
then make zImage and make s-recorde file.
Then download this file into sdram vai tftp,it just
hang at uncompressing kernel image, and can't boot
kernle.
I use linux2.4.4(from denx.de),MPC850, and HHL2.0's
compiler.
I have ment this questions in many borad.

Thx!

Dear Dross Zhou,

What is this good for?

TFTP is a binary protocol, it needs a binary image,  not  a  s-record
file.

This is most probably due to the fact that your  firmware  expects  a
binary image but finds a text file.

What sort of firmware are you using anyway?
