In Theory it may be possible, but just for very tiny demo applications. Probably not for a useful device. > When Linux try to boot, there is this line on the terminal : > "Memory : 2036k available (1036k kernel code, 256k data, 80k init, 0k > highmem)" > So I have 2036k memory available for my initrd image but I don't know if this > is suffisant. Note that a ramdisk is NOT an efficient way to use memory. See fro example http://www.denx.de/wiki/view/DULG/RootFileSystemSelection which shows that for example a cramfs image is not only faster to boot but also needs less RAM.
