Re: [Gumstix-users] udev - 4MB Connex under OE

[Michael A. N. <ma...@ho...>]

I am at a loss to determine what can be eliminated.  I have commented the
lines for cron, boa, motd and www-content in the gumstix-basic-image.
Unfortunately, this only reduces the image size down to 3.1MB.  So I am
still overwriting some of the file system.

I am using the uClib based image.  Suggestions?  What is the difference that
allowed the buildroot builds to succeed?  The old UBoot?

Michael,

Sadly 3.7MB isn't good enough :-(

That's cause you only really have 3 MB -- the linux uImage eats up 1MB
at the top of flash.

So I imagine the missing file messages are because you over-wrote the
top of the root file system with the linux image.

More dieting is required :-(
