[gentoo-embedded] musl stages for armv5

[Stuart Longland]

Hi all,

I'm slowly pulling together a build of Gentoo/MUSL for ARMv5 machines.
Right now I've cross-compiled a build environment using OpenADK, thrown
that onto a Technologic Systems TS-7670, and let it rip.

I've had some set backs, with power black-outs and such, but the build
is chugging along on the little machine… which has similar
specifications to the old Cobalt Qube II that I used to use for
Gentoo/MIPS (mipsel4) stage builds.

CPU: Freescale i.MX286 at 454MHz (1 core)
RAM: 128MB
HDD: 1TB SATA via USB 2.0

Gentoo/MUSL is a good fit for these machines I believe due to the low
RAM footprint, and gcc aside (which takes nearly a week to compile), is
more manageable on this low-end hardware.

Is there any interest in the stages once they're built?

I think so. It might be good to get in touch with others working on
musl, I think blueness@gentoo.org is one.

I'm currently working on some armv6j musl stages also, but talking to
blueness, we might be on our own to 'support' them. That said, I agree
that Musl is a good fit for these lower-power CPUs, and am happy to
share thoughts/rubber-duck if it helps you. If you don't already,
perhaps hang out in #gentoo-arm on Freenode IRC, and we can collate ideas!
Best regards,

Michael.

Well, after months of grinding away at the problem, finally, I have some
stage tarballs.  (and I thought my Qube II was slow!)

http://repo.longlandclan.id.au/gentoo/stages/musl/arm/

I have not, as yet, tried booting that stage tarball, and as I type this
it's still uploading.  Soon as the DIGESTS file shows up, that'd be a
fair indication that the upload is complete.

I observe that Catalyst left behind a lock file in /, but I'm at the
point of "stuff it, this will do".  I can clean that up in later runs (I
might see if QEMU is faster).

This weekend, I plan to pull the little TS-7670 off the DIN rail and
throw a SD card in there with this image on it, with a view of replacing
the Debian install it presently has on eMMC.

I provide this image on the off-chance people may be interested.  It of
course, comes with minimal support if any.
