[gentoo-user] Booted Gentoo the first time on the Arietta.G25...but...

[meino.cramer]

Hi,

I am half the happiest person this evening... ;)

With a mix of Robert Nelsons super kernel sources for
ARM boards, the Atmel bootloader modified by acmesystems
(who produces the Arietta) and the stage3 for armv5 by
Gentoo and last but no least some luck the Arietta.G25
board is now booting the kernel and (seems) to access the 
Gentoo rootfs: The stored dmesg output tells about starting
udev, so I think the rootfs is entered.

Previously I had access to the board while using the
embedian image by acmesystems.
But Shortly after the board was released embedian.org
shuts down...the project died.
And I alway want gentoo on my systems...

Now the other not-so-happy part:
I still cannot access the board. Problem is:
It does not have a real (RJ45) ethernet port.
It uses ethernet over usb which works with the
debian image. 

I configured Robert Nelsons kernel with the kernel
configuration file by acmesystems - so this part should be ok.

How can I configure Gentoo on the Arietta board 
to use ethernet-over-usb  to be started while 
booting the Arietta board?

By "replace everything eth0 with usb0" ??? ;)

Thank you very much for any help in advance!
Best regards,
Meino

if you still have emdebian image you can boot that and see which modules
are loaded - that would be a start. a nice dodge is
# find /sys | grep drivers
you can also check everything in "make menuconfig"  under the section 
device drivers\network device support\usb network adaptors 
that everything you _might_ need is selected
there is a chance that the gentoo image has what you need --- what does
"lsusb" show you ? what about "ifconfig -a"
usb ethernet devices have very odd names ... names such as enp0s29u1u2  
so it would be "replace everything eth0 with enp0s29u1u2"

hi meino,
i was curious about the board you are using, and found this page
http://watchmysys.com/blog/2014/08/building-arietta-g25-kernel/
which says that the ethernet is a "Davicom DM96xx USB 2.0 10/100M
Ethernet Adaptor"
you need kernel modules dm9601 (USB_NET_DM9601)  and sr9700
(USB_NET_SR9700) in your kernel .config for this to work
good luck!

Meino,

You might also want to check if there is any firmware that is not being 
found/loaded.
For me, that is usually the case when something isn't working.

Hi thegeezer, Hi Joost,

it was that simple, that I *had* to overlooked it: The modules
for ethernet over usb had to be loaded before using that interface...
WUMMER!
Sometimes..... :)

I added the following modules:
  usb_f_rndis 
  u_ether 
  usb_f_ecm 
  usb_f_ecm_subset 
  usb_f_eem 
  g_ether 
  at91_udc 
  atmel_usba_udc 
  libcomposite

and I am not sure, whether some of them are not necassary for that
purpose...but with this in /etc/conf.d/modules it works.

Current status is:
* Board boots with Robert Nelsons linux kernel for ARM and a device
  tree blob by acmesystems and a stage3 rootfs (armv5tel) by the one
  and only Gentoo.
* The board is accessible via ssh
* I am currently downloading (emerge -f) some applications I need,
  compiling on this board is an exercise in patience... 8). After
  the download the board can compile the stuff without using my PC
  as router to the internet. So it does not harm to power the board
  with 100mA over several days...

Best regards,
Meino

You can't use distcc and a crosscompiler on your desktop for this?

Hi Joost,

I tried that for the Beaglebone Black I also use.
It will not work constantly enough well to setup
a complete system. There are two sources for trouble:
The makefiles access "meta-applications" like moc fpr qt
and either try to start a arm binary on my AMD64 PC or
they use moc of the AMD64 arch. and produce some rubbish
from the point of view of the ARM arch.
(ok, moc is bad example, since it is platform idenpendant
regarding ist outout I think, but...)
Or: The software isn't written that clean and import
low level headers (kernel...) of the AMD64 platform
into the ARM compilation results.
I also tried distcc and it does not work for me. 
May be its me or distcc. The results were..."mixed"...
Since that I compile all the stuff (accept the kernel
itsself because it is "self contained") on the target
itsself. With the beaglebone black this only a matter of
waiting (not THAT long: 1GHz CPU single core with 512MB RAM
and an mobile hd).
With that tiny Arietta and await waiting for days until
I have a system of my choice.
But that is ok, since the main purpose of this tiny Linux
thingy is only the steering of some electronics. Nothing fancy...
So I need only a few addtional applications.

But the beaglebone black is acapble enough to run SIMH
emulating a PDP11 with an ancient UNIX (with an original
login of Dennis Ritchie ;) at 100% "original speed".
Or an ATARi800 emulator (also at 100% original speed).
Or other nice things... :)

Best regards,
Meino

if you are having difficulty with [1] then you could always have an
emulator running on real hardware, doing distcc.  you can set distcc to
do no compiling locally by excluding localhost. then you can have your
multi cores running happily within a virtualbox doing nothing more than
compiling for the limited arm device.  
on the virtualbox device, if you then ensure to have in
/etc/portage/make.conf
FEATURES="buildpkg"
then you get binary packages for free. this means that if something goes
wrong with the the device or you want to do this again on another device
you can use emerge -K (as long as you set the package location in
advance of course) and the hours of compiling become copy, untar, install
