5208evb distribution runs on a 8MB board?

[Durian]

Hi, I downloaded the 5208evb ISO from the Freescale website and changed the DRAM size from 32MB to 8MB, and then tried running it on the 5208evb board again. It does not run but throw a memory alloc error when the init runs. Has anyone does this before successfully? Might it be something in the /etc/rcS or rc.conf?

Also has anyone attempted to rebuild the Busybox package from source? The build fails...

Thanks

Running a BSP in 8M of RAM requires disabling as many items as possible
in both the kernel and userspace.  Even then, when we tried to boot an
M5282EVB which has only 8M of RAM we encountered these same
problems.  8M is pretty small

What are the errors you're seeing with the busybox build?

[Durian]

Thanks for your reply.

Strange, I tried to disable Busybox from the package, but still the size of the filesystem is the same. Perhaps I am missing something?
Do you have a .config and app package config that worked for you on the 8MB board?

Here is the build error when building busybox... bash also cannot build...

Thanks

Here is the build error when building busybox... bash also cannot build...

Some of the parts in busybox haven't been ported to the uClinux environment.
Many of the archive utilities (like gzip and tar) and bash don't build.  I
believe only sash and msh build for shell utilities.

I've never tried to disable busybox completely.  (Busybox does provide your
shell, so you won't be able to boot if it's turned off.)  Maybe that's why the
filesystem size didn't change, it stays enabled to provide a shell.
