A good question about what’s new…
Sometimes the Mighty BeagleBone may ask for a new, unknown driver named SUBARCTIC. His VID is 0451 and PID is 6141, at least in the case of a A6a board.
A simple search about this can lead to a bunch of different opinions but the truth seems to be that is appears only in Sitara’s bootloader mode, when he waits for some other debugging options, maybe something on the non-soldered P7 JTAG Connector.
The BeagleBone Subarctic QuickFix
So, BeagleBone is built to boot something from the SD Card… Inserting the Linux SD Card all works fine, the board get into linux boot sequence, the right devices (USB Serial Port, RNDIS Gadget… ) are showing up and the drivers are loading.
The quick fix: don’t search for a driver instead put the SD Card with software in the connector and cycle power.
Here is a USBView capture of the SUBARCTIC issue:

A great product: The Bus Pirate v.3
The Bus Pirate v.3 is a great piece of open source hardware and software bundle, built by Ian Lesnet & Co. @dangerousprototypes that can easy substitute some quick-build interfacing adapter for I2C, UART, 1-Wire, SPI, MIDI and many other serial protocols.
One important thing is that is 5.5v tolerant and supports some scriptable binary bitbang. In other words you can test at bit level various things that supports syncronous and asyncronous serial protocols.
Is built around a FT232RL converter, a PIC24 and a smart power supply (5v and 3v3 supplied to the target as software option).
Some features here: http://dangerousprototypes.com/docs/Features_overview
Unfortunately… somehow I managed to burn his first 3v3 Micrel LDO (VR2 on the schematic/pcb). A short circuit on the cable connector and the LDO is gone.
To use the BusPirate again I had to switch the 3v3 LDO’s, the first one powers the board and the second one is for the “power to target” mode. Now the board is without the 3v3 supply option.

LPC800 series develeopment tool
It’s amazing. Simple and efficient.
The small pin number is compensated in a great way: The Switch Matrix – it connects 6 pins to any available internal module.
Of course, programming can be done in bootloader mode, where every pin is reassigned according to the original layout.
- ARM Cortex-M0+
- Switch matrix for flexible configuration of each I/O pin function
- 2 USART interfaces, 1 SPI controller and 1 I²C-bus, with pin functions assigned through the switch matrix
- Self Wake-up Timer (WKT) clocked from either the IRC or a low-power, low-frequency internal oscillator
- CRC engine
- Boot ROM API support: boot loader, USART and I²C drivers in ROM, power profiles, Flash In-Application Programming (IAP) and In-System Programming (ISP)
The debugging options supported are SWD (10 pin connector), JTAG boundary scan and Micro Trace Buffer (MTB).
The quickest/cheapest programming method is via
spi*ISP (6 pin connector) with a USB/Serial cable.

Energia, something between TI Launchpad series and Arduino/Wiring
http://energia.nu/ is awebsite that bring Energia, a Wiring/Arduino IDE fork designed to ease the Ti Launchpad series integration into the maker/hobbyist world.
In conjuction with the low price of the Launchpads and the growing number of the Boosterpacks I think that TI hits it big!
Right now it supports the following LaunchPads: LaunchPad MSP430G (MSP430G2231, MSP430G2452 and MSP430G2553), FRAM Launchpad aka. FraunchPad (MSP-EXP430FR5739), Stellaris LaunchPad (EK-LM4F120XL ).
No C2000 for now.

installing and running elinks – the text mode browser – on a BeagleBone
BeagleBone is great!
wget http://www.elinks.cz/download/elinks-current-stable.tar.gz tar - xzvf elinks-current-stable.tar.gz cd elinks-0.11-20130125 (better press tab after elinks, the last part is the date) ./configure make && make install
and finally get to google:
More Angstrom tools:
systemd, is a system and service manager, a initd replacement
systemd uses journal instead of syslog
journalctl – a “/var/log/messages” replacement
configuration file: /etc/systemd/journald.conf
journalctl can be used in conjuction with grep
opkg – the package manager, a ipkg fork
updating the system : opkg update (?)
package information: opkg info <package name>
install packages: opkg install <package name> (ex. samba, a good way to build windows networks)
top – shows running tasks
top with no arguments – shows all tasks
top -p <pid> –shows only that specific pid
Installing nmap on BeagleBone
Maybe the best network scan tool available, the powerful nmap is also free.
wget http://nmap.org/dist/nmap-6.25.tgz cd nmap-6.25 ./configure make make install
The install procedure takes some time (>20 minutes)
To get the basic help run nmap without arguments.
the make step is displaying 2 errors but is ok, make install shows 1 error but it works.
Installing mtr on a Beaglebone/Angstrom
mtr(former Matt’s traceroute) is a mix of traceroute and ping, I use it often in network diagnose. Running it on BeagleBone simplifies many things.
As a usual source install:
wget ftp://ftp.bitwizard.nl/mtr/mtr-0.82.tar.gz tar -xzvf mtr-0.82.tar.gz cd mtr-0.82 ./configure make make install
well… cursesX is not available… but is ok, I don’t want to run X.

Midnight Commander 4.6.1 running on BeagleBone with Angstrom Distribution.
BeagleBone is a linux box. So get all the classic linux tools!
mc aka Midnight Commander is a visual file manager (orthodox file manager) used in console work. It is released under under GNU GPL.
For those who are not familiar with mc it is a product in the line of nc – Norton Commander, Path Minder, dn – Dos Navigator, far, Windows Commander / Total Commander.
mc v4.6.1 runs smooth on BeagleBone/Angstrom, mc v220.127.116.11 needs the S-Lang Library (http://s-lang.org) so I skipped it.
Installing mc from source is simple but it takes some time for every step, is not like installing it on a server but you have enough time to read the full output without redirecting it to a file 🙂

Great! But I’m still waiting for the new tideals site…
One of the coolest DMM on the market:
Fluke 233 – the Remote Display Multimeter
This is a great DMM, but mine has a problem: the battery life!
Leaving the meter in OFF state, after some weeks, all the batteries are dead. Happened 4 times with different batteries.
It seems that the power-off state consumption is high and approximately the same value for both units.
Some guys from Element 14 are stating that is a flaw with the meters with s/n under 138xxx:
