I am trying to reduce the size of uclinux currently is now 3.5Gb and I was wonding if someone could tell me the what files could be removed to decrease this size and still allow uClinux to compile.




Thank you,

Take a look here:




This page also include config files.


It's not a big deal getting below 1MB.

i'm fairly certain you're quoting the size wrong.  i *highly* doubt your kernel image is 3.5 gigabytes.


at any rate, read the FAQ (My uImage is too large to burn in my flash):

I think that the poster was referring to the size of the complete uClinux distribution uncompressed, and its space on disk... and not the kernel image

i didnt think the dist was that big (yet)


there is no document on how to trim it done ... just `rm` the directories you dont want


or even simpler: just buy a bigger hard drive

Hi, I do as below:


1. in user dir , del no used application source code. only remabin busybox & some other app u needed. The user dir is very large.


2. Del some cpu support source code(bus the dir & config file must remain for make menuconfig). The related dir:








3. Del no used lib in dir lib


4. Del some no nused drivers file in drivers


Now my dist package is 357MByte.  It's can be smaller.
