It is targeted to an I486, 16MB DRAM, 16MB DiskOnChip. I have decided to use Redhat 6.2 (2.2.14 kernel) and to reduce its size to fit the EPC. I have simplified the kernel (removed support of all unwanted hardware), init scripts and amount of apps I will really need. I do not have problems with its size on disk (8MB), but I do see a problem in its memory requirements. It takes now about 11MB. It is too much. I tried to replace init by sulogin to get bash shell and look into the system memory as soon as possible, but again without starting any daemon only with bash running I got 7MB. I am asking you, is there any option to tell Linux kernel "save the memory" or what are the general recommendations to minimize amount of memory the kernel consumes?
