Gentoo on Embedded

M1Sports20 · Posted: Thu Dec 08, 2005 1:32 am Post subject: Gentoo on Embedded

Does anyone think it is possible to fit a basic linux, apache, mono. fit in 90 megabytes. I only have 128 megs of ROM, and need about 20 megs free for my use.??

If so can I get some recommendations. Is gentoo the right distro to try? Once its up I don't need package management, but I will have to fix security flaws

thanks

at my last job, we successfully squeezed a fully functional FreeBSD install onto a 128 meg stick of compact flash, for use in a router (pc talking to a T1-CSU/DSU through a pci card) which needed to boot quicker

had the base install, and all the utils needed for routing squeezed down to about 80 or 90 megs.
the big chor was manual removal of -every- file we could tell we would never need, and not running (and deleting) system services like logging and cron

WOW that's a cool profile, but I have another questions... I will make a gentoo stage3 running in a motherboard that runs a PXA255 Xscale... is possible with the /usr/portage/profile/embedded do that?

Oops... last but not the list... eh eh eh
To begin develop or instaling software wich packages in portage did you suggest me?

I think first of all crossdev, and did you know a good emulator? Do you utilize another packages?

Thanx and excuse me for the double post

with gentoo, i built a complete rootfs including the following:

uclibc, baselayout-lite, busybox, perl, dropbear

to fit on a 6mb strataflash

in fact, the rootfs is about 14mb large, but i use jffs2 as the filesystem on my flash and that fs has a buildtin compression, so that all the stuff takes about 5,4mb (including some kernelmodues) on the strata-flash

Here I am again

I look at that Guide in the Wiki; well, since I wanted to build a ARM development enviromet, I installed crossdev to build the cross-chains tools like gcc/uclib/gdb and now I don't know what to do.

In the guide the following steps are listed:

Hi, I'm here again, I would like to know something: in the past I have readed that gentoo supporting the uclinux project with the kernel and the libs... Here was write that there is the uclinux-sources in the portage repository, but now there isn't true...
Well now I will begin to support a XILINX platform named MICROBLAZE and I know that the uclinux support that device, I'm interested to port gentoo on that architecture, is possible?

Cheers

it wouldnt really make sense at this time unless you feel like doing a lot of work

otherwise you should just fetch the sources from http://uclinux.org/

Hello everybody,

I am searching to fit on a STB box from ST, that is based on ST5100 or ST5514/5518 chips, a minimal Gentoo Linux version.

The hardware is from ST (I beleive 6805 at the origin but I can be wrong), and the box has 4 Mb of Flash and 64 Mb of Ram.

Thanks,

Jan

P.S. : See for hardware specs,

Excellent, the new generation of boards is based on 5100 and 7100 (Mpeg4)... PVR receivers !

If you are interested by the hardware, let me know as I could get samples that could be really nice, based on the STi5100 and the STi7100.

I've gotten an embedded system that is almost 8MB that does Linux, http server and ssh server (with busybox).

You should check out an excellent cross-compile development, complete with toolchain, root file system and ten dozen packages for small system.
