Use of NetBSD with Marvell Kirkwood Processors and AK-Systems' IP-Plugs
article by Vladimir Trubilov
that explains what NetBSD is and how little effort
is needed to get it going on a new ARM platform,
AK-System IP-Plug mini-server
as an example
(Wikipedia link; the AK-System website is only in Russian-language!).
The article outlines the history of the various BSDs
and tells about NetBSD's source organization and build process.
It then introduces the target hardware and how NetBSD
abstracts the various busses and drivers that are already
there, and the few bits that needed adjusting.
``Conclusion: High portability, sufficient ease of use, as well as the necessary software packet and an open source code packets and open source make NetBSD a very attractive operating system for use in embedded systems. As seen in the example, it takes quite superficial knowledge of the system architecture and minimum change in the code to run NetBSD on the IP-Plug. At the same time, the functionality and performance of the built operating system is not inferior to that of Linux, which is used by default.''

Max uptime: 8 years, 122 days!
This weekend's In Other BSDs
the DragonFly BSD Digest
an interesting discussion
in which a NetBSD system with 8-year uptime is introduced. Quoting
from the ~October 2013 article:
`` I set up a dialup gateway for a company with NetBSD 1.3 in 1998 on a compaq pentium 90 desktop with 32MiB of RAM. I got a call last year (!) from the owner saying it stopped working suddenly. Pulled the disk on it and plugged it into an IDE/USB adapter and looked at the syslog as I had no ps2 keyboard and it didn't have USB.
Suspected hardware failure at that age.
Max uptime: 8 years, 122 days!''
The article goes on about what the machine was used for, and a bunch
of lessons learned.
Have a look and learn!
g4u 2.6beta1 released
I have release g4u version 2.6beta1. Important changes are an update
to recent NetBSD codebase, and moving the ramdisk from a separate
file back into the kernel. This allows easy netbooting - at least
I hope so, feedback is welcome here.
I'd like to push out version 2.6 within the next few weeks.
Please test and let me know if there are any showstoppers!
Full list of news in g4u 2.6beta1:
- Make this build with NetBSD-current sources as of 2013-10-20
- Move back from a ramdisk that's loaded from a separate file back to a
ramdisk that's part of the kernel image. This allows easier netbooting
for those people who want it - added back by popular demand :-)
- Added more kernel buffer space, to hold all kernel messages for dmesg,
even on machines with large ACPI tables (Hello VMware Fusion!)
- New drivers:
- LSILogic 9x9 and 53c1030 (Fusion-MPT) PCI SCSI
- LSI Logic Fusion-MPT II PCI SCSI
- Atheros AR9k (802.11a/g/n) PCI Wireless
- Marvell PCI Libertas Wireless
- Atheros AR9k (802.11a/g/n) PC-Card Wireless
- Broadcom BCM43xx PC-Card Wireless
- Atheros AR9002U USB Wireless
- Ralink Technology RT2500USB 802.11a/b/g USB Wireless
- Ralink Technology RT(2|30)00 802.11a/b/g/n USB Wireless
- Realtek RTL8187/RTL8187B 802.11b/g USB Wireless
- Realtek RTL8188CU/RTL8192CU 802.11b/g/n USB Wireless
- Intel Atom E6xx PCI-LPC

G4U Opinion Time: kernel with embedded RAMdisk vs. miniroot?
my own mail to the g4u-help mailing list: ``I've found little time to hack on
g4u in the recent past. Yet, I've
managed to setup my development and test environment for g4u
(crosscompiling NetBSD from Mac OS X, getting recent Qemu to compile), and
also got g4u built from recent NetBSD-current sources. As such, take this
as small sign of life.
Now, while I don't have any plans for large changes, I'd like to bring an
update with latest drivers and bugfixes from NetBSD.
There's one change that I'm pondering, though: g4u originally came as one
kernel-file that had an embedded RAM-disk. This was changed in the last
release to reflect NetBSD's ability to load a RAM-disk from a separate
file. This change broke the ability to netboot g4u from a single file, and
required some more effort. There were no real wins for g4u as such.
So, opinion time: keep the RAM-disk as separate file, or move it back into
Looking forward for your opinions!''
Mercedes Benz powered by NetBSD?
a posting by Fefe
which links to
Open Source licenses used by Mercedes Benz.
This includes a number of BSD variants - original 4-clause as well as the 2- and 3-clause versions
as well as company specific BSD licenses by car-supplier Continental,
Acme Labs and Google.
No explicit mention of NetBSD's license,
but a bunch of NetBSD developers' names and mail addresses can be found.
There is also an overview that the BSD license is used in about all
models from A-Class over S-Class to SLK,
and which also indicates that the new (2013+) S-Class
includes much more BSD licensed software than all the other models.
Which is not much of a surprise, as it's the most recent and
also most technically advanced model (as far as I can tell).
No details are included as to what software components
are under the respective licenses. Anyone got details?

Quick bootstrap of NetBSD on Raspberry Pi and Cobalt machines
NetBSD is a fine operating system, but the installation
sometimes leaves a lot of rope to hang yourself on non-PC
platforms. To make things easier to get a recent NetBSD
version on the Cobat Raq and Qube machines,
Izumi Tsutsui has
released a Restore CD/USB image based on NetBSD 5.2.1
that allows for a quick bootstrap.
There is also a
Restore CD HOWTO
available with more information.
If you're into somewhat more recent machines, the Raspberry Pi
is for you. For easy bootstrapping of NetBSD, Jun Ebihara
offers a SD card image
with -current NetBSD and pkgsrc from October 2013 preinstalled.
This also includes support for hardware floating point and DMA.
are available on line in Japanese language.
The important commands still are readable, so have a look!

Raspberry Pi USB HC driver change - DMA support added
that he has ``recently switched the Raspberry Pi kernel to dwctwo(4) a new USB drvier based on the Synopsys code. It's a more complete driver than the previous dotg(4) and has DMA support''.
that the driver works fine with a dmesg extract, and also lets us
know that the driver will be in his next RPI image.
This change does not only affect the Raspberry Pi, but also
other machines that have a Synopsis USB like the
OpenBlocks 600, as KIYOHARA Takashi
lets us know.

Google Summer of Code 2014
Yes, 2014 - Google today
announced the 10th anniversary
of its Summer of Code. NetBSD participation is still
being sorted out, but can be expected.
the blog post
for more information.
First and foremost, use this early news to think
about possible projects, get familiar with NetBSD
(which you probably are if you read this), and
sort out your summer occupation 2014.
Embedded NetBSD on iMX233/OLinuXino
Petri Laakso has
worked to get NetBSD
going on the
ARM board, specifically the MAXI and MICRO boards. The port is stable enough to run multiuser and build software from pkgsrc. Supported hardware include
USB host, and
a boot loader.
The hardware is ways below 50 EUR, so this is a good start to
get a nice and easy machine. More information on how to get things
running are available
in Petri's blog.
Last, the impatient souls that can't wait to start playing can
find the code in NetBSD-current
already, thanks to Matt Thomas.
