I'm a embedded systems consultant, and either between assignements, or taking a 
sabbatical year, or retired.  I don't know which it is yet.  Take further 
discussion offline; my email address is on the website.

[beagleboard] RE: What are we doing about the conversation about software, source, hardware, and beagleboard.org boards currently?

[Philip Munts]

I've written some application notes (available at 
https://github.com/pmunts/muntsos/tree/master/doc) that I always thought should 
become chapters in a book about embedded systems development using Linux.  Two 
of them are directly applicable to the BeagleBone and kin and most of the 
others are indirectly applicable.  I'd appreciate it if you would read through 
them and tell me how well (if at all) they would satisfy your search for 
information.

Re: [beagleboard] Pins and Port configuration in the Beagleboard xM

[Philip Munts]

config-pin.c isn't part of the kernel; it is just a C reimplementation of the 
userland config-pin script.  It isn't a perfect replacement.  It eliminates the 
platform configuration tables in the script, but it has some limitations.  One 
that comes to mind is that config-pin -q will display "default"  for a pin that 
has the default configuration, but doesn't tell you *what* the default 
configuration is...

[beagleboard] Pins and Port configuration in the Beagleboard xM

[Philip Munts]

You could try my config-pin replacement written in C:  
http://git.munts.com/muntsos/bootkernel/initramfs/config-pin.c

Unlike the original config-pin script, my replacement derives all pin 
configuration information by reading files in /sys, and doesn't have any 
platform dependencies.  I haven't used an xM in years but it seems like it 
ought to work.

[beagleboard] GNU Modula-2 for the BeagleBone

[Philip Munts]

I have finally gotten around to building a native GNU Modula-2 compiler package 
for Debian Stretch on the BeagleBone.  It took about 9 hours to build on a 
SanCloud BeagleBone Enhanced with 1 GB of RAM.  I wasn’t able to build 
successfully on a regular BeagleBone with only 512 MB of RAM.

Packages built from 8.2.0+gm2-git-latest for the BeagleBone, Raspberry Pi 1, 
and Raspberry Pi 2 (as well as x86 and x86-64) are available from my Debian 
package repository at http://repo.munts.com/debian9.  These packages install 
everything in /usr/local/gm2.

Modules for libsimpleio (http://git.munts.com/libsimpleio) are under (slow) 
development.

[beagleboard] GPIO failed: No such file or directory

[Philip Munts]

It is a race condition.  The GPIO pin files don't exist until the pin is 
exported by writing the pin number to /sys/class/gpio/export.  The pin files 
are created neither instantaneously nor synchronously.

Your code or library is trying to open one of the pin files after exporting but 
before the pin file is ready.

[beagleboard] Grove adapter for PocketBeagle

[Philip Munts]

I couldn't find anything like this so I had to develop it myself:

https://www.tindie.com/products/pmunts/mikrobus-grove-adapter-3/

It works great in a BeagleBone Click Shield or a mikroBUS Cape, too.

[beagleboard] Off the Wall: .Net Core on the PocketBeagle

Here is a seriously off the wall but fun project:  How to develop .Net Core

smallest system that can run .Net Core (at least among boards that are commonly 
available).

[beagleboard] ANNOUNCE: MuntsOS Embedded Linux for BeagleBone

[Philip Munts]

We are pleased to announce MuntsOS, an embedded Linux environment, with support 
for BeagleBone and Raspberry Pi boards.  MuntsOS is a RAM resident operating 
system environment that is very easy to install (just unzip one file to an SD 
card) and very lightweight.  It is particularly suited to headless embedded 
applications.

Cross-toolchains for Ada, C, C++, Fortran, and Free Pascal are provided.  Run 
time interpreters for C#, Java, and Python 3 are also provided.  Applications 
written for MuntsOS typically use libsimpleio for controlling I/O devices and 
can be highly portable even between board families like the BeagleBone and the 
Raspberry Pi.

MuntsOS is entirely open source.  All original works are copyrighted and 
licensed under a 1-clause BSD license.  Binaries are generally GPL because of 
the components they contain.

[beagleboard] PocketBeagle SPI device nodes

[philip . munts]

My PocketBeagle, running a custom 4.9.57 kernel and standard device tree, 
creates the following SPI device nodes:

usbgadget# ls -l /dev/spi*
crw-rw1 root gpio  153,   0 Jan  1 00:00 /dev/spidev1.0
crw-rw1 root gpio  153,   1 Jan  1 00:00 /dev/spidev1.1
crw-rw1 root gpio  153,   2 Jan  1 00:00 /dev/spidev2.0
crw-rw1 root gpio  153,   3 Jan  1 00:00 /dev/spidev2.1

Why are there four device nodes?  Normally there should be a single device 
node for each slave select, and the
PocketBeagle pinout only lists one slave select for each SPI bus controller.

Which device nodes correspond to which slave selects?  (It appears to me 
that spidev1.x might correspond to McSPIO0
and spidev2.x might correspond to McSPI1).

[beagleboard] am i doing this right?

[philip k]

i'm attempting a build.  

I will be using 5 pressure sensors.  here are the specs:

Pressure Range: 0-200 psi
Output: 0.5V – 4.5V linear voltage output. 0 psi outputs 0.5V, 100 psi 
outputs 2.5V, 200 psi outputs 4.5V
Working Temperature: -40—+125ºC;.
Accuracy: ±1%FS;
Thread: 1/8"-27 NPT.
Overload Capacity: 2 times;
Pressure Medium: The gas and liquid which is compatible with 316L stainless 
steel;
Load Resistance: ≤(supply power-6.5V/0.02A)Ω;
Long-term stability: ± 0.2%FS/year;
Temperature Effect on Zero: Typical: ±0.02%FS/ºC; Maximum: ±0.05%FS/ºC;
Temperature Effect on Sensitivity: Typical: ±0.02%FS/ºC; Maximum: 
±0.05%FS/ºC;
Shock Resistance: 100g;
Anti-Shock: ≤±0.01%FS(X,Y,Z axes, 200Hz/g);
Response Time: ≤1ms;
Insulation Resistance: >100mΩ  500VDC;
Explosion-proof Class: ExiaTTCT6;
Electromagnetism Compatibility: EN50081-1; EN50082-2; IEC6 1000-4-3 ;
Wiring connector: water sealed quick disconnect.  Mating connector and wire 
harness (pigtail) is included.
Wiring: Red for IN+.  Black for GND.  Green for OUT.

would i be correct by running a 600Ω resistor parallel to each sensor to 
bring the voltage down to ≤1.8v and go from pin 7 or 8 to the five sensors, 
then run sensor1 signal and a 600ohm resistor in parallel to pins P9 35, 
sensor2 signal and a 600ohm resistor in parallel to P9 36, and so on?

thanks for any input.

Re: [beagleboard] Re: ssh using USB

[Philip Polstra]

BBB uses USB multi_g driver which supplies ethernet and USB mass storage
that exports the built in flash storage.  You can learn more about how this
works from my DEFCON 23 talk "1 device to pwn them all".  Just Google it
for video and slides.

Re: [beagleboard] USB Mass Storage/Fix dyndbg value in U-boot?

[Philip Polstra]

What OS are you running on the BBB?  In most cases the BBB will export a
Linux USB gadget which is a composite device with mass storage and Ethernet
enabled by default.  Your Mac may need a driver.  Also passing USB devices
through to VM is not automatic.

Re: [beagleboard] Good small (e.g. 7 to 10 inch) displays for BBB

[Philip Polstra]

I have had good luck with the 4D systems capes.  You will find that with
any LCD display like this the power requirements are pretty high, however.
Most of the power is for the backlight.  You might be able to find a LED
backlit system, but that will likely be more money.

Re: [beagleboard] Re: RAM 1GB option

[Philip Polstra]

I would like to see the price difference.  It would be nice to have a
cheaper board and perhaps a premium board for some things.  The upgrade
from 2GB to 4GB on the board doesn't do anything for me since my OS is much
larger than that, but yet only the more expensive 4GB boards are
available.  Would hate to see something similar happen with the RAM.  The
only reason the BB Green is at all attractive to me is not because it has
the Grove connectors, but because it is cheap and I could use it for my
hacking drones.  For the times that I need more RAM the 1GB boards that are
already available are nice.

Re: [beagleboard] WiFi with external antenna for BBB - recommendations?

[Philip Polstra]

Most adapters work.  If you are just trying to connect to a network you
don't have to be picky.  If you are using your BBB for hacking like I am,
then you might want something like the Alfa AWUS036H.

[beagleboard] Making a lunch box computer with the BBB

Re: [beagleboard] DEFCON BBB talks

[Philip Polstra]

4 days in Vegas at the world's largest hacker con for $230.  Something for
everyone.  Bigger than ever this year with villages for hardware hacking,
crypto, lock picking, wireless, and probably some I forgot.  Parties every
night with great performers.

In addition to my two talks, I'll be demoing the BBB and CatchWire at the
first ever DEFCON Demo Labs this year.  We will also be giving away some
stuff from WAW Technologies including two gift boxes worth more than $500
each with:

A CatchWire appliance and all accessories

XBee radios

XBee USB adapters

32GB microSD running a special version of The Deck Linux

My "Hacking & Penetration Testing with Low Power Devices" book and

an early release of my "Linux Forensics" book.


I do have some no-wait tickets available at face value for anyone not
wanting to wait in line with 15,000 people.  Just e-mail me off the list.

Re: [beagleboard] SD Card via USB

[Philip Polstra]

The first time you plug in the thumb drive it should be /dev/sda.  If you
want the SD card its /dev/mmcXXblk where XX is either 00 or 01 depending on
what you booted from.  The part of my script that unmounts drives is
unneeded for SD cards, but you still need to run modprobe -r g_multi to
unload the default device which doesn't export the SD card.  Then if you
run modprobe g_multi file=/dev/mmcXXblkXX it should show up on the PC.

Re: [beagleboard] SD Card via USB

[Philip Polstra]

You want to use the USB gadget to export the SD Card filesystem.  This is
similar to something I'm doing for an upcoming DEFCON talk.  Here is the
script for that talk:

#!/bin/bash
# stop the GETTY service if needed
if which 'systemctl' ; then
  systemctl stop serial-getty@ttyGS0.service >/dev/null
fi
# unload current composite gadget
modprobe -r g_multi
# these variables are used to export all partitions
fstr=""
rostr=""
# unmount the USB drive
for d in $(ls /dev/sd*) ; do
  if  echo "$d" | egrep '[1-9]$' >/dev/null ; then
umount $d
fstr+=",$d"
rostr+=",1"
  fi
done
fstr=${fstr:1} # strip leading comma
rostr=${rostr:1} # strip leading comma
echo "$fstr" >/tmp/usbexports # save for later r/w export

# now export it
vend=$(( 0x1337 )) # pick your favorite vid/pid
prod=$(( 0x1337 ))
echo "$vend" >/tmp/usbvend # save vid/pid for r/w export
echo "$prod" >/tmp/usbprod
modprobe g_multi file=$fstr cdrom=0 stall=0 ro=$rostr \
  removable=1 nofua=1 idVendor=$vend idProduct=$prod

[beagleboard] LCD cape with 4.1 kernel

[Philip Polstra]

Has anyone gotten any LCD capes (4.3 or 7") to work with Ubuntu and the 4.1
kernel?  Cape Manager seems to error out when loading firmware.  Everything
also seems to be mostly blank (no pins used, no pinmux values, etc.).

[beagleboard] DEFCON BBB talks

[Philip Polstra]

As an FYI, if any of your are going to DEFCON, I will be giving two talks,
one related to the BBB, and one to the CatchWire (formerly LUNA) that is
essentially a customized BBB with two gigabit Ethernet ports.

The BBB talk is this one
https://www.defcon.org/html/defcon-23/dc-23-speakers.html#Polstra and the
CatchWire talk is
https://www.defcon.org/html/defcon-23/dc-23-speakers.html#Polstra2.

We will also be giving away 2 CatchWires each with a copy of my Hacking and
Penetration Testing with Low Power Devices and my (new) Linux Forensics
books.  You can register to win these at the PentesterAcademy booth.

I'm also hoping to release version 2.1 of The Deck Linux at DEFCON for the
BBB and a custom edition of Deck Linux for the CatchWire.

Re: [beagleboard] Re: Up, up and away and x15

[Philip Polstra]

As someone who has actually shipped small items like PCBs for my XBee cape
and XBee cape kits internationally, I can tell you that this is not really
steep at all.  For example, sending 3 PCBs to the UK in a regular envelope
cost me $11.  Priority mail is $22 and Express Priority mail is close to
$50.

Re: [beagleboard] much value in BB-xM anymore?

[Philip Polstra]

Once the X15 is out I plan on building a "laptop" that has an X15, two
BB-xMs, and an unknown number of BBW and BBB boards connected together in a
Beauwolf cluster with a big touchscreen and multiple wireless adapters.  It
will be the replacement for my current Buzz Lightyear (Hack you to infinity
and beyond) lunchbox with a BB-xM and 7" touchscreen.

The GUI should already be installed.  If you hook the BBB up to a TV or

Re: [beagleboard] Re: The Deck 2.0 (Linux for penetration testers) for BBB now available

[Philip Polstra]

You should be able to put the files together and extract them all at once
using the command "cat TheDeck*.tar.gz-part-0* | tar xzv" from any linux
machine. If this is problematic you can try to do it in two steps like this:
cat TheDeck*.tar.gz-part-0* > TheDeck*.tar.gz
tar xzvf TheDeck*.tar.gz

Alternatively, you can download the entire thing from my website at the
university http://facstaff.bloomu.edu/ppolstra.

[beagleboard] No IP Address on new image (Rev C)

[Philip Theis]

So I take a new Rev C board.  Works fine with the April Deb image out of 
the box (bone47).  Get IP address fine.
Went through the process of installing the May Deb image (bone50)
Start up the new image and it does not obtain an IP address; all conditions 
are the same.
Is it the image?

Re: [beagleboard] BeagleBone Cape EEPROM format update

[Philip Polstra]

I remember populating this info for my XBee Cape, only to find that it is
not used at all.  I think it is still a good idea to have the info in there
in case it is really used in the future.  In theory it should be possible
to have the cape configured without the need for a DTB file for each cape.

[beagleboard] GPIO_40 vs PWM

[Philip Theis]

I attempting to use GPIO_40 on P9_14
It is not responding as other GPIO pins are.
My assumption is that since it is dual purpose with PWM1A that the PWM is 
keeping it from being used as a GPIO digital output pin.
How can I stop the PWM process that is keeping GPIO_40 from working?
thanks,
Phil

Re: [beagleboard] Change the VID/PID for the client USB port

The VID/PID doesn't determine what driver is loaded.  That is determined by
the device class/subclass/protocol which is either provided in the device

Re: [beagleboard] Relay Alternative for a Low powered module on/off

[Philip Polstra]

If you are using the regular and pro 2.4GHz XBee you don't need anything
close to 1A.  The hardware pin sleep is so low power that turning it off
makes little sense.  Just my two cents from the guy who builds low power
hacking drones.

[beagleboard] XBee capes

As an FYI.  I have printed circuit boards and full kits for the XBee cape
described in my book (Hacking and Penetration Testing with Low Power
Devices) available at http://philpolstra.com/Hacking-Kits/ if anyone is
playing with XBee and ZigBee.

On-board programming of the radios via 3.3V FTDI cable is support.

There are also updates to the MeshDeck available at
http://facstaff.bloomu.edu/ppolstra.  The latest version has better support
for Series 2 (ZigBee) and adds things such as the the ability to query a
radio for its short address by entering the lower 4 bytes of the MAC

Re: [beagleboard] Re: Books or Internet resources on Embedded linux

[Philip Polstra]

If you aren't doing anything with hardware (using capes, etc.) then doing
C/C++ on the BBB is no different from any other Linux system.  There are
lots of resources for that kind of stuff.  Even if you want to talk to
external devices using serial communications (UART) or some other standard
protocol it's all the same once you have configured the pins on the BBB to
do what you want.

Re: [beagleboard] Loading custom capes on Debian

[Philip Polstra]

I suspect it is a problem with your dtbo file.  I believe that some of the
dtbo files that used to be installed in /lib/firmware have been essentially
compiled in to the kernel in an attempt to fix some other issues.  My dtbo
for my XBee cape is still in /lib/firmware and it works fine.  Doesn't
automatically load off EEPROM at boot, but the running "echo
XbeeFullCape0001>/sys/devices/bone_capemgr.9/slots" as root works.

Re: [beagleboard] Maximum SD card size for BBB

[Philip Polstra]

Would SDXC work if reformatted to get rid of Microsoft's proprietary exFAT
filesystem or is the hardware limited to 32GB?  Just curious, haven't
needed anything larger than 32.

[beagleboard] New version of MeshDeck (XBee remote control)

[Philip Polstra]

For any of you that are using the MeshDeck to remotely control your BBB
over an XBee link, I have just pushed out a new version 2.0.1 which is
available at
http://facstaff.bloomu.edu/ppolstra/MeshDeck/MeshDeck-2.0.1.tar.gz.  The
new version includes a device tree overlay for my XBee cape which will
likely work for others provided you are using the /dev/ttyO2 port to
connect to  your XBee.

In addition to including the overlay, I have made a slight addition to the
daemon startup file so that it will check for the existence of /dev/ttyO2
before starting the MeshDeck.  If the device doesn't exist, the overlay is
loaded.  This was needed to overcome a problem where the system correctly
reads the cape EEPROM 0.9 seconds into the boot process, but then fails to
retrieve the firmware from /lib/firmware, presumably because the root
filesystem is not yet mounted.

For anyone that is interested, I do plan on having the boards, XBee cape
kits, book bundles, low-power hacking starter kits, and ultimate starter
kits that include everything you need to get started with low-power hacking
(book, XBee cape kit, preloaded microSD, BBB, USB XBee adapter, XBee pro,
and XBee regular) available for purchase soon at http://philpolstra.com as
well as some other places.

[beagleboard] rc.local not run under Ubuntu

I have upgraded to Ubuntu 14.04 on my BBB and suddenly the /etc/rc.local

experienced this or have a suggested fix?

Re: [beagleboard] PRU - Low Latency I/O

[Philip Polstra]

Just wanted to add my book
http://store.elsevier.com/Hacking-and-Penetration-Testing-with-Low-Power-Devices/Philip-Polstra/isbn-9780128007518/
to the list from Jason's presentation (it came out after his
presentation).  In addition to the hacking stuff, there are chapters on
using XBee/ZigBee to remotely control the BBB, power requirements, and
developing your own Linux distro.  Those developing real time and/or
robotics projects on the BBB might find the information useful.

[Philip Polstra]

Just an FYI for anyone contemplating buying my book Hacking and Penetration
Testing with Low Power Devices which is about building cheap, but powerful
hacking hardware from the BBB:

Syngress is running a sale on all their books where you can get a DRM-free
eBook for free when you buy a print book with deal code BOGO or up to 40%
off anything with deal code DELTA.  The net of this is that you can get the
eBook for $44.96 or both for $59.95 at
http://store.elsevier.com/product.jsp?isbn=9780128008249.

Re: [beagleboard] Wireless mesh networking

[Philip Polstra]

It really depends on what you are trying to do.  The nice thing about
Zigbee is that you can configure the modems and then sit back and let the
network form, heal, etc. without any work on your part.  If you are only
interested in communications between nodes then Zigbee is a great choice
unless you need high speeds (250kbps is typical max speed).  This book
http://shop.oreilly.com/product/9780596807740.do has lots of good info on
Xbee/Zigbee (most of which is in my book) and is geared more toward Arduino.

A tip on my book: Syngress currently has a deal where you can buy the print
book and get a DRM-free eBook for free till October 9 at
http://store.elsevier.com/product.jsp?isbn=9780128007518.  Be sure to add
both to your shopping cart to get the free eBook.  The deal code is BOGO.

Re: [beagleboard] Wireless mesh networking

[Philip Polstra]

I am using 802.15.4 (Zigbee) to connect BBBs together for security
penetration testing.  I am running my custom Linux, The Deck, to do this,
but you should be able to do the same with Debian or Ubuntu (which mine is
based on).  Logic systems started selling capes for this.  I have been
making my own.  Design is in my book
http://store.elsevier.com/product.jsp?isbn=9780128007518 and I'm planning
to sell some capes commercially as well soon.  One warning about the Logic
Systems capes: they lack the EEPROM which tells the BBB what they are so
you need to manually set that up on the BBB using the device tree overlays.

Re: [beagleboard] Beagle Bone can't ping or ssh

[Philip Polstra]

If you have connected the ethernet cable between the PC and the BBB that is
likely the problem.  You need to plug the BBB into a router so it can get
an IP address assigned.  By default, it is setup to get a dynamic IP
address via DHCP.

What are you connecting the Ethernet cable to?  Which Linux distro are you

Re: [beagleboard] Why is it using BBB in commercial products not encouraged?

I have some bb-xm and original beaglebone boards I have been running since

You can base commercial products on this board and people do so.

I have boards running nearly continuously for years.  I think the thought

Does it have to be a 10" or would a 7" do the trick.  The screens from 4D

[beagleboard] Best place to get BBB in Europe?

[Philip Polstra]

I'm doing a workshop related to my book, Hacking and Penetration Testing
with Low Power Devices, on building remote hacking drones from the BBB in 2
weeks at BruCON.  Does anyone have recommended sources for the BBB in the
EU for my workshop attendees?

Thanks,

Dr. Phil

Re: [beagleboard] Ubuntu on Beagle Bone Black

[Philip Polstra]

Check your SD card to be sure there is a uenv.txt file in the boot
partition.  I have seen the file not get changed from uenv-BBB.txt which
leads to this problem.

Re: [beagleboard] Strange question from a newbie

[Philip Polstra]

Not 100% sure about what would happen in your case.  I am running Ubuntu
14.04 with LXDE which I added on myself after the initial install.  As a
result everything I expect to be in the menu is in there.  Might be a
better way to go and safer too.

Re: [beagleboard] The Deck 2.0 (Linux for penetration testers) for BBB now available

[Philip Polstra]

Not terribly familiar with ArchAssault.  In fact, I had no idea they were
using the MeshDeck or 4Deck (not that I have any problems with that).  I
will say that Kali admits that it doesn't work well on the BBB.  This is
because it is just a straight port of an Intel based system.  The Deck was
meant to run on the ARM platform from the start.  It offers a lot more when
it comes to things like scripted attacks.  It is also meant to be used in
an environment where downloading new packages is difficult.  That is why it
includes over 4k packages from the start.  Also, don't know what desktop
Kali uses, but I'm using LXDE which is pretty lightweight.  The Deck runs
on my 7" 4D systems touchscreen with no issues.

[beagleboard] Some upcoming BeagleBone books

[Philip Polstra]

There are some interesting upcoming BeagleBone books that I'm aware of:

BeagleBone For Secret Agents by Josh Datko
https://www.packtpub.com/hardware-and-creative/beaglebone-secret-agents

A yet to be titled book by Bill Pretty who previously wrote Building a Home
Security System with BeagleBone
https://www.packtpub.com/hardware-and-creative/building-home-security-system-beaglebone

I was a technical reviewer on both of these books.

Finally, my own book on building hacking hardware based on the BeagleBone,
Hacking and Penetration Testing with Low Power Devices, is now available
for pre-order at Amazon
http://www.amazon.com/Hacking-Penetration-Testing-Power-Devices/dp/0128007516

Re: [beagleboard] Re: BBB failure to boot, due to our cape.

[philip]

I am aware that Rom means read only.
I am aware that I need to fix the cape on the next revision

My question
Is the ROM, hard coded silicone? OTP? Or JTAG flashed, all of which are 
commonly referred to as ROM.

The time to spin new hardware is longer than the GSOC students have to do their 
projects, so I am looking for a short term fix.

If it is hard coded, I will have no choice but to spin new hardware, that's the 
question

[beagleboard] Re: BBB failure to boot, due to our cape.

[Philip Rowse]

Cc'd to the BBB group as well

Where can we fond the code to the Boot Rom?  For the next revision of our cape, 
I will be fixing the enable, I am aware of this, the power too the level 
shifters was to be enabled via the SYS_RESETN, but it has caused other issues, 
so now it is hard connected via a jumper.

There are only a few of these capes for development purposes, so we would like 
to modify the ROM to allow for this on these capes.

There will be further changes to revision 2 of the cape, but before that, I 
need to allow development to continue, regardless of hardware issues

For this application, being an autopilot, we are going for a fixed 
configuration, so we do not have any unexpected behaviour during flight, due to 
user configuration changes.

Thanks
