New binary releases for NetBSD on Raspberry Pi, including 7.0 RC1
NetBSD runs on many machnes, and the Raspberry Pi is one of them.
Getting the stock distribution is not that easy, and to help
in getting things going, Jun Ebihara is providing
ready-made images for quite some time.
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.''
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.
NetBSD on BeagleBone Black HOW-TO
NetBSD runs on a number of ARM platforms, and the
is one of many such platforms. It comes with Linux by default,
and as such there are a few adventures to make if you want
NetBSD on it.
NetBSD on the Raspberry Pi
is a pretty recent, cheap ARM-based board, or as the
says: ``An ARM GNU/Linux box for $25''.
Shipping with today's Windows-for-embedde-boards
operating system (AKA Linux), there's also a port of
NetBSD on its way.
Nick Hudson is at it, and he has posted first
now, showing the machine going to multiuser mode.
The code's not integrated into mainline NetBSD-current yet,
but rest assured that that will happen when the code is ripe.
Good work, Nick!
NetBSD ketchup - news from my mailbox
Here's another bunch of NetBSD-related news that has
been lingering in my inbox for far too long:
restore CD is available based on NetBSD versions
for information on what it is and how to use it.
A negative symbol lookup cache was added
to NetBSD's loader
for shared libraries and shared objects, ld.so_elf, by
``I've been researching why Evolution from GNOME takes over 5 minutes to load on my quad core amd64 beast. It boils down to dlsym looking for a symbol that does not exist directly and as such examining every needed library. However, the current implementation does not remember what libraries it as already checked. Normally this isn't a problem, but with the way Evolution is built the search chain is massive.
With this patch, Evolution (without the patches to and a glib I added to pkgsrc a few days ago) loads in under 2 seconds (5 seconds with initial disk thrashing). ''
The NetBSD Logo
is available in many variants, but a new variant was submitted
via www@ these days by "Tim" - which is actually plain HTML,
SafeNet's ProtectDrive is
``a full disk encryption solution that encrypts the entire hard drive of laptops, workstations and servers, as well as USB flash drives, to protect data in the case of the theft or loss of a hardware device.''
How do you implement such preboot authentication and
harddisk encryption software,
esp. if you want to provide thinks like LDAP integration for
the user/key handling and two-factor authentication?
Little is known, but rumors say the 32bit version of the software
is based on NetBSD, as is backed by
this worker bio info:
``Duties: Working on pre-boot restricted environment with loads before operation system and implemented on NetBSD.
Ported and optimized the KDrive X server to NetBSD.
Developed and implemented user secure authentication interface with smart card support.
Environment and tools : NetBSD (3.0), C/C++, FLTK''
A german-language introduction of pkgsrc on OpenSolaris
was given by Michael 'kvedulv' Moll at the Munich
OpenSolaris User Group back in march.
``I have now fairly good (i.e., it works for me) support for the
MINI2440 on NetBSD with support for the following:
- S3C2440 UART
- DM9000 (MAC+PHY)
- S3C2440 SD Controller
- S3C2440 DMA Controller
- S3C2440 IIS Controller
- FriendlyArm 3,5" LCD Display
- S3C2440 USB Host Controller (OHCI)
- S3C2440 Touch Screen
- UDA1341TS audio codec
Currently, support for three things on the S3C2440 are missing:
- S3C2440 NAND Controller
- S3C2440 USB Device Controller
- S3C2440 RTC
I've also created a stage2 bootloader for use with u-boot, which
ensures that the value of bootargs is passed to the NetBSD kernel.
At this point I have only tested the code with the 64Mb version of the
FTOS is the operating system software that runs on Force10 switch/router product lines, including the E-Series, C-Series and S-Series platforms. Based on NetBSD, FTOS leverages a distributed, multiprocessor architecture that delivers highly scalable protocols and reliability. By delivering the same OS across its entire switch/router line, Force10 ensures that customers benefit from stable code, a consistent configuration environment and simpler software management. ''
Force10 Networks Delivers Ethernet-Optimized Platform for MPLS Core Networks:
``Force10 Networks, Inc. [...]
announced the immediate availability of MPLS (multi-protocol label switching) functionality for its ExaScale E-Series core switch/routers.
The ExaScale platform combines high-density, non-blocking, line-rate 10 GbE switching and routing with robust MPLS LSR support at 1/5th of the cost of a traditional core router, enabling carriers to fully capitalize on the economic advantages of Ethernet.''
Create Bootable Live Linux USB Drives with UNetbootin:
``UNetbootin allows you to create bootable Live USB drives for a variety of Linux distributions from Windows or Linux, without requiring you to burn a CD. You can either let it download one of the many distributions supported out-of-the-box for you, or supply your own Linux .iso file if you've already downloaded one or your preferred distribution isn't on the list.''
And of course we all know that NetBSD is Linux, right?
See the list of supported distributions:
mentions that NetBSD 4.0 is supported, maybe someone wants
to give them an update on what's up with NetBSD 5.0?
Would be nice to see that on the list!
With the move from XFree to X.org, the X server for the DNARD Shark's
NetBSD/shark lost support for accelerated X.
Thanks to Michael 'macallan' Lorenz,
hardware-accelerated X for NetBSD/shark is back now:
``I finally got around to start working on an Xorg driver for the IGS CyberPro
20x0 family found in rev. 5 Sharks, Netwinder etc. - currently the driver is
built only on shark and supports only the VL variant found there. Adding
support for PCI chips is trivial though, just needs extra probing.
The driver supports autoconfiguration ( X -configure should yield something
almost usable, only DefaultDepth needs to be adjusted).''
Jed Davis has committed the
RAIDframe parity Summer-of-Code project.
for the details. The project
the time RAIDframe spends rewriting parity after an unclean shutdown by
keeping better track of outstanding writes (thus, "parity map"). The
tech-kern archives have more details [...]
This feature is enabled by default on all sets (other than RAID 0). It
can be administratively disabled with the new "raidctl -M" flag, which
is described in the changes to the raidctl(8) man page; however, the I/O
overhead for updating the parity map is expected to be unnoticeable in
So much for now. There is more in the pipe, but that will have
to wait for now. Good night!
