The thing is:
I will need to work with files (new firmware should arrive to sdcard on 
the board through ftp in a main app). I want redboot to pick a new image 
up from sdcard at reset.
Extracting sections from received ELF file and transferring them to 
redboot is more of a manual work.
So, I think I am kind of stuck with ELF files.

So I am thinking:

* Should I load compressed ELF file (gzip) with -d switch?

* Should I load SREC file (they are usually smaller than ELF)?

* Should I save executable sections and store them in a file. Transfer 
that file to sdcard for redboot to pick it up at reset.
(nor sure how to do it actually)

* Can I actually load a .bin (image in binary format)?

Thanks.
