Hi Bob,

I am looking into the question: How many resources (flash and RAM) are required to run a (typical) uClinux-system?
This depends on a lot of things, so it is hard to give any reasonable answer. As a data point I have built uClinux systems that had 1MB of RAM and 1MB of flash. It will depend on: 1. linux kernel version 2. which libc you use 3. what application set you choose.
At some places I read, that each piece of software that is part of (uC)linux is loaded from disk, decompressed and executed in RAM. On the other hand: From my previous (introductory) sessions with uClinux on a MCF5282-based board, I know that uClinux is written into the flash using romfs and at some other place I have read, that romfs is not compressed. Does this mean that programs stored in romfs are executed in place? Or does one have to take special measures to achieve this?
There are a number of ways to setup the kernel and filesystem. Depends on what RAM and flash tradeoffs you want to make.
