@ILF,

how is your arch-arm image working on the imx? I just started with the ubuntu image delivred with the imx and it is terrible slow, so I thought to try the linaro version. At the end I will definitely swith to archlinuxarm when it is stable on the imx53 as I don't have much time to troubleshoot now (father of a girl twin of 10 months and rebuilding my house -> very tired...)

regards

$this->bbcode_second_pass_quote('kmihelich', 'A') kernel to test is in the repo, named linux-imx5 and based on Linaro sources for 3.1-rc9. Give it a shot and let me know what happens.


Can you please send a link to where in the repo it is? I would like to try it out ... what filesystem version do we try it out with?

Thanks,
Bernie

Use the omap-smp tarball as a base, that's the armv7h variant. The kernel package is in core, pacman will find it.

Sorry for the delay .. finally have some time to try this out.

A question: So I build an SD card image with the omap tarball .. and I boot initially with the omap kernel,t hen replace with the imx53 kernel via pacman and boot the new kernel?

Is this the process? Will the omap kernel even boot on an i.mx53 target?

Thanks,
Bernie

You'll want to use the omap tarball, chroot in after you extract, then install linux-imx5 replacing linux-omap. You should then be able to boot that new rootfs after doing whatever you need to do with /boot/uImage.

Can You chroot from an I386 OS in a ARM OS? You need a VM with an arm OS running to work in, no?

Use what you have running on the device now, you'll need an ARM environment. You should be able to prep the new install that way.

$this->bbcode_second_pass_quote('kmihelich', 'U')se what you have running on the device now, you'll need an ARM environment. You should be able to prep the new install that way.


Ok, I have had a go at bootstrapping Arch this way, but ran into a road block. What I did was:
1. Created a spare SD card with the current Ubuntu linux on it so I can hack it ...
2. Copied the omap tarball to the card
3. Booted using the SD card.
4. In the environment uncompressed the omap root image ON TOP of the ubuntu root file system

However, after doing those steps I can no longer use sudo, it complains about an unknown uid : 1000
so I cannot use pacman to upgrade the kernel image.

Any suggestions welcome ... I presume you have tried this approach before ;-)

EDIT: I found the root password(from docs) so using "su" managed to be root user and that worked.
I chroot'ed into "/" and tried to update the database with "pacman -Syy" and I now get this error:
"error: failed retrieving file 'core.db' from archlinuxarm.org : No address record"

Any idea's

Probably needs dns in resolve.conf, if network is up

Cool that did it .. I had forgotten to do that step :shock:
