is there any document of how to generate ELF binaries of programs made by myself runnable by LinuxBios,Filo,Etherboto loading ELF binaries ?
The binary has to be self contained, i.e use no external services. And it needs a defined entry point.. Stack setup and similar things are wishful but not necessary iirc.
For example: LinuxBios + myprogram, or LinuxBios + Filo + myprogram_from_dsk or LinuxBios + etherboot + myprogram_from_X
I was looking something in dietlibc but at the moment it does'nt work.
dietlibc will probably not work since it uses system calls..
newlib might be used as a start point to build a libc replacement for environment without OS.
However, the quick way I think is to use freebios/util/baremetal or modifying FILO.
I once tried to build an MP3 player inside BIOS, by modifying FILO. It succeeded to play an MP3 file from hard disk in 3-4 seconds from reset.
