[Avila] IXP 400 Access Libary and Ethernet Drivers

Fri Dec 8 00:30:51 EST 2006

Joel,=0A=0AYes, the 8M limit is easily overcome with a newer genextfs - tha=
t has nothing to do with Snapgear and of course thats the uncompressed size=
 not the compressed flash size.=0A=0AI'm very understanding of your dilemma=
 as I also use openssl and am constantly fighting the size of my RFS (equat=
es to memory usage when your loading that RFS into a ramdisk).=0A=0AI'm sur=
prised to here that uClibc makes that big of a difference.  I would be conc=
erned about side-effects it may have on apps (or build issues as you may be=
 running into) because of some of the limitations it uses to reduce size.=
=0A=0AWhat other libs are you using?  Show us a 'ls -lR romfs/lib'  One of =
my distributions is rather full-featured including an http server with php,=
 and openssl and still fits within a 14MB uncompressed filesystem and a 5.5=
MB flash partition - granted this seriously pushes the limits of the 8MB/16=
MB flash/ram the 2347 has.  With openssl whats probably killing you is libc=
rypto because it contains all the crypto's even the ones you possibly don't=
 need.  You may be able to trim that down by building openssl yourself and =
disabling crypto's you don't require.=0A=0AAnyone else using uClibc or have=
 any comments on it?=0A=0ATim=0A=0A=0A----- Original Message ----=0AFrom: J=

ponses.=0A=0AI have integrated about 10 packages into snapgear, have upgrad=
ed the madwifi=0Aand done several other things to my build environment.  It=
 is working great=0Aexcept that I have eclipsed the 8M limit of the ramdisk=
 and had to start=0Ausing a different genfs program to make my ramdisk.  =
=0A=0AThe biggest problem is that my library directory is almost 6 megs whe=

rses=0Alibrary for dialog and rrdtool library in addition to openssl librar=
y which=0Ais where all the size comes from.  I don't know much about lib op=
timization=0Aso I don't know if I can make the libraries any smaller.=0A=0A=
I wanted to use uClibc to try to get back below the 8M snapgear limit which=
=0Ameans I need to get my libraries about 1.5 Megs smaller.=0A=0AThanks rea=

=0AJoel,=0A=0AAs Tim mentioned...use the Gateworks BSP CD. It is prepared s=
pecifically for=0A=0Athe Avila. The prebuilt zImage/ramdisk.gz images that =
are in the =0A/tftpboot/2.6 directory on the BSP CDROM (typically same as i=
n flash) are =0Acompletely usable and do have a pretty recent version of wi=
reless tools =0Awithin them. They are ready to burn into flash.=0A=0ATo sav=
e you unneeded stress....do no try to build uClibc via SnapGear (SG). =0ASt=
ick with glibc which is set as default on the Gateworks BSP. I know of no =
=0Aother benefit to using uClibc at this time other than sizem which is rea=
lly =0Anot too much of a concern to many folks anymore.=0A=0AIs there some =
other reason you need to use uClibc?=0A=0A=0A=0A=0A-Dave=0A=0A> Thanks Tim,=
