I had a simular problem. I ended up writing my own code for my platform.

A quick question.. I have developed a primitive bootloader for custom board, that is successfuly doing the board bringup and loads linux os image currently through serial link (kermit) only. network link is also likely to be up soon. but through serial it loads kernel image only in raw binary format. now i want to extend this for s-record images as well.. I am umware that, how differently s-record image need to be handled..? i just need some idea or if possible any example code for that.. Best Reagards, Atul
