Re: [Gumstix-users] run latest verdex kernel from onboard flash

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 454-5900

I have also been trying to use the git repo with a Verdex Pro w/ netpro
(R2210) and wifi module.
No success with the wifi module yet, but I have built 2.6.31 and a rootfs
and booted them from
the on-board flash.

The good news:
1) If you're already running u-boot 1.2.0 you don't have to flash u-boot,
you can get away with just doing the following instead:

GUM> setenv bootcmd "icache on; setenv stderr nulldev; setenv stdout
nulldev; if pinit on && fatload ide 0 a2000000 gumstix-factory.script; then
setenv stdout serial; setenv stderr serial; echo Found gumstix-factory.scrit
on CF...; autoscr; else if mmcinit && fatload mmc 0 a2000000
gumstix-factory.script; then setenv stdout serial; setenv stderr serial;
echo Found gumstix-factory.script on MMC...; autoscr; else setenv stdout
serial; setenv stderr serial; katload 160000 && bootm; fi; fi"
GUM> saveenv

2) Some tweaks have to be made to the kernel in order for the large kernel
size to work. Patch follows:

Subject: [PATCH] Modify kernel 2.6.31 to boot from u-boot

Enables necessary config options to make kernels bootable. Including
building-in JFFS2. Changes kernel size in Verdex's flash patch to
0x160000 -- without this the kernel WILL overwrite itself.

3) rootfs is bloated with a bunch of stuff inherited from Angstrom, which I
don't have a use for, so I hacked it
all out. You'll probably want to pass on this patch but if you want a quick
and dirty head-start towards a
rootfs that will fit on the Pro, here you go:  (BONUS: Also fixes a typo.)

Subject: [PATCH] Tweak distro and task to shrink rootfs

Disables a bunch of packages that I don't need in order to create a
smaller rootfs (one that will fit on the Verdex Pro, 16MB.)

YMMV!

---------------------------------------------

I haven't yet unlocked the magic that'll make the wifi module work but I do
have a buildable
system. Hooray!

Here's what happens when I try to fire up the wifi:

root@gumstix-verdex:/# modprobe libertas-cs
lib80211: common routines for IEEE802.11 drivers
root@gumstix-verdex:/# /etc/init.d/cf8385 start
Starting Marvell Wifi CF8385...
pcmcia_socket pcmcia_socket0: pccard: PCMCIA card inserted into slot 0
pcmcia 0.0: pcmcia: registering new device pcmcia0.0
libertas_cs 0.0: firmware: requesting libertas_cs_helper.fw
/* pauses for about a minute here */
libertas_cs: can't load helper firmware
root@gumstix-verdex:/#

:-(

root@gumstix-verdex:/# ls /lib/firmware/
libertas_cs.fw         libertas_cs_helper.fw  libertas_license.txt
root@gumstix-verdex:/#

Any ideas? I'm not familiar with the firmware-binary-blob-handling
subsystem, so this could be
a simple fix.

FINALLY, Major props to you, Ash, for getting a git repo going. I don't know
how much is your
influence and how much comes from how things are done with the Overo but the
layout of the
files is waaaaay cleaner than the svn setup. BitBake/OE still seem like
messy spaghetti* to
to me but working with your repo has made me feel like I have a fighting
chance :-P

Okay, I'm sure I missed a lot of stuff but I hope there is something helpful
in here for someone.

G'nite!

* Someday I'll learn to accept it for what it is and wield its power. In the
mean time I'll keep saying stuff like that.
Today "bitbake -c mrproper gumstix-kernel" deleted the _entire_ contents of
my _/usr/share/sources_ _directory_.
What the f-ck is that?! Gigs and gigs and gigs down the drain. Poof. I will
never talk to mrproper ever again.
'clean' ftw.
