Hi, What would be size of smallest Linux kernel? Yes, I mean plain vanilla with only bootup message on console.

Compile it and see for yourself :)

Yes very true but, 1. I am not kernel expert and dont know what is essential for kernel. 2. If some one has already done it, why invent the wheel. 3. The list is for exchange of idea (as I understand). 4. And finally if you dont know the answer, dont reply.

BTW, I wanted to know this because I am trying to port kernel to ARM processor with 512K flash and 64K RAM.

LPC2138 with MMU (not sure)

Which ARM? MMU-less/with-MPU/with-MMU?

512K is built flash.

Which flash? NOR/NAND? Do you have any other flash on-board?

Again 64K is built in.

What RAM? SDRAM/SRAM?

If you are using MMU, you'll want to have a filesystem (ramfs/cramfs/jffs2/et. al.) along with the kernel on

I am just exploring the possibility of putting a workable kernel + romfs on the chip. Some people have already ported ecos on LPC2292 (with 4MB flash and 16MB Ram). My idea was to load the small kernel and boot it up to init. And depending on space, expand the files. Should I look for older kernel version like 2.0?
