Giles,

If you tested the mount externally and it works this probably wouldnt be a
NFS issue. Just on a guess form experience and what you've posted. the
kernel is loading, but the rootfs isnt. Your debug messages seems to nearly
confirm this. So if you can add the line mentioned on my blog post to
inittab ( which is copied from Roberts guide ), perhaps you'll get more
information as to what is exactly happening.

Good luck, ill be on later today. Bed time for me.

 Subject: [beagleboard] unable to boot Beaglebone Black from NFS

 I've seen many posts about how to boot a Beaglebone black via an NFS
 mounted root partition, but none seem to work with the latest version.
 I started by creating an NFS mount on my Ubuntu PC and successfully
 mounting it from the Beaglebone when booted from an SD image of the latest
 version dated 2013.06.20
 https://s3.amazonaws.com/angstrom/demo/beaglebone/Angstrom-Cloud9-IDE-GNOME-eglibc-ipk-v2012.12-beaglebone-2013.06.20.img.xz
  from
 the Beaglebone site. All the commands below were done as root.;
 uname -a
 Linux beaglebone 3.8.13-bone50 
 Then test the mount with;
 mount -o nfsvers=3 192.168.10.118:/home/bone /mnt/nfs
 Next I copied the entire filesystem to the nfs mount with
 cp -axv /. /mnt/nfs/.

 I’m not sure this is going to work because you are attempting to copy
 dynamic files and folders. Rather insert the SDCard into your host and do
 the following:
 sudo rsync -avz /mnt/rootfs/ /home/userid/targetNFS/


 I've edited the fstab on the nfs (/home/bone/etc/fstab) to add
 /dev/nfs / nfs defaults 0  0
 and correctly edited /home/bone/etc/network/interface to reflect the
 correct IP address etc.
 Next I edited the uEnv.txt on the SD card to add
 serverip=192.168.10.118
 ipaddr=192.168.10.47
 hostname=MH_bbb
 netmask=255.255.255.0
 gateway=192.168.10.1
 nfsdevice=eth0:off
 nfsopts=vers=3
 rootpath=/home/bone
 and changed the mmcargs line to;
 mcargs=setenv bootargs console=tty0 console=${console} ${optargs}
 ${cape_disable} ${cape_enable} ${kms_force_mode} ip=${ipaddr}:${serverip}:${
 gateway}:${netmask}:${hostname}:${nfsdevice} root=/dev/nfs rw
 nfsroot=${serverip}:${rootpath},${nfsopts}  ${systemd}
 The Bone starts to boot and I can ping it on the correct IP address, but
 the display never shows anything and it doesn't let me ssh to it.
 Can anyone let me know what I've missed?
 Thanks

 This is my complete uEnv.txt:

 ==
 client_ip=10.100.116.105
 server_ip=10.100.116.73
 gw_ip=10.100.116.1
 root_dir=/home/userid/targetNFS
 ==

 Replace userid with your own desktop login id and replace client_ip,
 server_ip and gw_ip addresses as required.

Re: [beagleboard] unable to boot Beaglebone Black from NFS

By the way I was contacted by another party last year who told me that my
blog guide for NFS rootfs wont work with Ubuntu, and fedora. But will work
for Debian ARCH, and BusyBox.

So I have to assume the init daemon for these other distro's are the
culprit. However, if you can find a known working guide from anywhere on
the web ( i386 guide ) and adapt it . . . you should be golden.

Now, if you were willing to switch to Debian on both host and BBB I know it
would work if you followed my guide to the T. But perhaps that is too
much of a leap for you.

Re: [beagleboard] BeagleBone Black not detected after partion and unplug usb cable

2014-07-30 Thread Chan Le Van

Hi, Thanks for your answer but my board seems to be sleeping.
Actually, in the first time I plug my board to the laptop, it works fine 
with the power light turned on and 4 LEDS operate normally. But I want to 
install the Ubuntu on it, so  I follow the instruction here:
http://www.armhf.com/boards/beaglebone-black/bbb-sd-install/
after finished the step g(Finally, commit the changes by selecting w to 
‘write’ the partition table and exit fdisk.), 
I unplugged the usb cable. From that, when I connect the board by USB cable 
again, then my board is not starting normally anyomre, the OS  in my laptop 
is not showing the notification about new device has been plugged into it 
and the LEDs are not lighting as well, just the power light in the board 
turned on.
I followed the link you posted but in this, it says that: Use the provided 
microSD card to SD adapter or a USB adapter to connect the SD card to your 
computer.
So does it mean we have to use the external SD card which can communicate 
with the board by the SD card slot and use it to to some next steps to boot 
? When I receive my board, all I have are just the board without the 
external SD card and the USB cable ! So in my situation, what should I do 
to make my board return to the original state ?
Thanks for your help.

Sure? EEPROM documentation says, write-protection is disabled when WP-input

the trick.

BeagleBone Black System Reference Manual Rev C page 113| (in bright red 
font):

There are several precautions that need to me taken when working with the 
expansion
headers to prevent damage to the board.
1) Do not apply any voltages to any I/O pins when the board is not powered 
on.
2) Do not drive any external signals into the I/O pins until after the 
VDD_3V3B rail is up.
3) Do not apply any voltages that are generated from external sources.
4) If voltages are generated from the VDD_5V signal, those supplies must 
not become
active until after the VDD_3V3B rail is up.
5) If you are applying signals from other boards into the expansion 
headers, make sure
you power the board up after you power up the BeagleBone Black or make the
connections after power is applied on both boards.
Powering the processor via its I/O pins can cause damage to the processor.

Those kind of assumptions might kill your board.

Re: [beagleboard] Re: Maximum current on GPIO?

2014-07-30 Thread karlkarpfen79

This doesn't answers my question. So to describe it more clear:

- board/CPU is powered and running
- SYS_RESETn is HIGH
- GPIO is configured as input
...so all preconditions mentioned in BBB manual are met.

Now when I want to set a HIGH signal to that GPI, can I connect it with 
BBBs 3.3V directly or is a resistor needed in order to keep this 8 mA sink 
limit?

Yes.

No. (You must observe the 8 mA limit, but connecting a GPIO to the 3.3V 
or gnd rails will not require anything close to 8 mA.)

Re: [beagleboard] Re: Maximum current on GPIO?

2014-07-30 Thread kyle

A GPIO configured as an input will not draw substantial current from the line 
it's connected to.  It is sensitive to the charge level on the line and will 
not draw current from it (exempting the gate capacitor charge-up).  A GPIO that 
is set to OUTPUT a high signal is now a potential source of current.   If you 
hook that up to the + end of a motor it will try to power the motor with the 
output.  In that case you MUST insure that your circuit limits the current to a 
maximum of 6mA.  The same is true if you OUTPUT a low signal.  Hook that to the 
- lead on a motor and the + lead to supply and the CPU is now trying to absorb 
all the current from that motor and will go poof.  

So if you were to connect directly to the positive supply and say somehow that 
pin ever becomes an output that is low you now have a dead short through the 
I/O pin and at best you'll fry that pin or its whole bank, you'll likely kill 
the whole chip.  Since the I/O on these devices is programmatic I never like to 
connect a pin directly to the supply rails.

 Why would this need to be funded by kickstarter or indiegogo campaign? 
 Me personally this turns me off the project regardless. 

 How is this going to be better/different than the current AP's on the 
 market, such as APM, UDB, PixHawk, Paparazzi, Open Pilot or the many other 
 proven solutions? What kind of testing is going to be done and currently 
 done to prove the AP software/hardware? How long has the flight software 
 been developed? What limitations will this board have? What control algos

Re: [beagleboard] Using SPI in a kernel module

 Subject: Re: [beagleboard] Using SPI in a kernel module

 Thanks, John.

 I Iooked at kernel/drivers/iio/dac/ad/5064.c

 There's the following struct which is passed to *spi_register_driver()*:
 static struct spi_driver ad5064_spi_driver = {
 .driver = {
.name = ad5064,
.owner = THIS_MODULE,
 },
 .probe = ad5064_spi_probe,
 .remove = ad5064_spi_remove,
 .id_table = ad5064_spi_ids,
 };

 I compiled the module and loaded it but the probe function never gets 
 called. Why?

 From this I can see that this driver isn’t DeviceTree enabled so I’m not 
 sure which SPI interface it is using. Either you can add the devicetree 
 support to this driver so that you can specify which SPI interface to use, 
 or e-mail the Linux-IIO mailing list and see how to use this driver. 

 Regards,
 John

 Subject: [beagleboard] Using SPI in a kernel module

 Hello,

 I'm currently working on a kernel module which needs to communicate via 
 SPI to an external microchip.

 I used the cape manager to enable SPI. The device is accessible through 
 /dev/spidev1.0.
 But since it's a kernel module, I guess it's not recommended to access 
 files via sys_open()?

 Another approach I found would be adding a struct to 
 *arch/arm/mach-omap2/board-am335xevm.c 
 *and then use *spi_register_driver()* in my kernel module. But in my 
 kernel sources (3.8.13) this file doesn't exist.

 There is no board files since the introduction of device tree.



 What would be the right way to use SPI in my kernel module?

 Look at examples in /drivers/staging/iio or /drivers/iio

 There are plenty of examples of using SPI calls in a kernel module. 

 Use the power of GIT to find what you are looking for. In the Kernel 
 source do the following:

 git grep spi_sync_transfer

 Regards,
 John

 Nils

[beagleboard] SHT20 I2C temperature sensor isn't detected

2014-07-30 Thread Tatsuya Sasaki

Hi all.
I hooked up my sensirion SHT20 temp/humid sensor to my BBB.
http://www.sensirion.com/en/products/humidity-temperature/humidity-sensor-sht20/

-SHT20-  -BBB-
GND --- P9-01
VDD --- P9-03
SCL --- P9-19
SDA --- P9-20

The datasheet says the address is 0100 (0x40).

 5.3 Sending a Command
 After sending the Start condition, the subsequent I2C 
 header consists of the 7-bit I2C device address ‘1000’000’
 and an SDA direction bit (Read R: ‘1’, Write W: ‘0’). 
 The wiring is like the following.


I expected to appear the sensor on I2C-1's address 0x40.
But it isn't detected:

$ sudo i2cdetect -r -y 1

 0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f

00:  -- -- -- -- -- -- -- -- -- -- -- -- --

and also

50: UU -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 

60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --

I checked the sensor worked as a normal I2C device on my Arduino. 

Do I need to install some drivers on BBB for the sensor?
Or do I missed some procedures?

As an update, I can get my beagleboard working with the Angstrom distro and 
the Gentoo distro following their basic setup.

Is there a trick to getting Ubuntu to run on a Beagleboard?

Lucid and Maverick ARM port is armv7 and higher compatible

It is an ARM 7 so anything over 10.04 should be good.  I've tried 12.04 and 
14 without luck.
Both logs point to missing .so files.

Going to try a rootstock and see if I can get that to work.

[beagleboard] BBB Debian Corrupt LCD

2014-07-30 Thread James S



We have a built a custom board with an LCD interface to drive a 1024 x 768 
pixel LVDS panel, 16BPP. It works great on the Beaglebone White with the 
old Angstrom 3.2 using the board file configuration.

We want to use the Beaglebone Black so we built up a system from 
http://elinux.org/Beagleboard:BeagleBoneBlack_Debian#2014-07-22 . I added a 
dts using the same parameters from the old board file but the graphics are 
blurred and corrupted. The card I made boots on the White also and gives 
the same results as on the Black. See images below.

I’ve fiddled with the panel timings but they don’t seem to have any effect.

Does anyone have any idea what is wrong and how do I fix it?

Re: [beagleboard] BBB Debian Corrupt LCD

If you read the manual, you will see that these lines are also connected to
the HDMI chip. To use it also as an LCD panel, you need to buffer these
signals and account for any noise that may be introduced as a result of
the loading of these 6ma drive signals my the HDMI chip.

Re: [beagleboard] Re: BBB Debian Corrupt LCD

Still could be the same issue. What buffer are you using to drive the
signals to the LVDS device? Are the trace lengths match to insure that all
the setup and hold times are met by having all signals with the same delay?

Re: [beagleboard] Re: BBB Debian Corrupt LCD

2014-07-30 Thread James S

Gerald,

The pins are connected directly to the LVDS chip, a DS90C383BMT. Trace 
lengths are short and matched. 
But on the same board with the older software, it worked fine - what would 
have changed to require the use of a buffer?

Regards,
James

Re: [beagleboard] Board won't flash

2014-07-30 Thread Tristan Phillips

Brilliant, I was just about to ask that.  So I have my kernel build honed 
now, and can get our board without ethernet booting by removing the TI 
drivers,  there are other kernel options I will play with later.

So, to sort out a flasher, or use a non flasher as a flasher, even 
manually?  (I have had no luck simply touching the trigger file...)

Much appreciated :)

Re: [beagleboard] Re: Maximum current on GPIO?

2014-07-30 Thread Brandon I

The gpio are push pull/pseudo open drain, so there's a transistor/switch
going from 3.3V to the pin, and a transistor going from ground to the pin.
When you set the pin high, you're turning on only the transistor to 3.3V,
so it's sourcing the current from 3.3V, through the transistor, out of the
pin. When you set it low, you're turning on the transistor to ground, so
it's sinking the current into the pin, through the transistor, and to
ground. If you have both off (high impedance), there isn't any significant
current going anywhere (I think it's some nA).





On Wed, Jul 30, 2014 at 6:11 AM, k...@cranehome.info wrote:

 A GPIO configured as an input will not draw substantial current from the
 line it's connected to.  It is sensitive to the charge level on the line
 and will not draw current from it (exempting the gate capacitor charge-up).
  A GPIO that is set to OUTPUT a high signal is now a potential source of
 current.   If you hook that up to the + end of a motor it will try to power
 the motor with the output.  In that case you MUST insure that your circuit
 limits the current to a maximum of 6mA.  The same is true if you OUTPUT a
 low signal.  Hook that to the - lead on a motor and the + lead to supply
 and the CPU is now trying to absorb all the current from that motor and
 will go poof.

 So if you were to connect directly to the positive supply and say somehow
 that pin ever becomes an output that is low you now have a dead short
 through the I/O pin and at best you'll fry that pin or its whole bank,
 you'll likely kill the whole chip.  Since the I/O on these devices is
 programmatic I never like to connect a pin directly to the supply rails.

[beagleboard] Re: Can the BeagleBone Black be used for industrial designs?

2014-07-30 Thread darek . fanton

As has been mentioned, while it was developed as a community supported 
platform, the BeagleBone can be used for any application you choose. For a 
time, there was a lack of sufficient supply to meet the demands of larger 
scale projects, but that is generally no longer the case. The topic of 
utilizing BBB for industrial applications is explored further here 
- 
http://www.logicsupply.com/blog/2014/05/15/new-embest-board-opens-door-for-beaglebone-black-projects/

As for industrial projects that do not require graphical interface, we're 
currently working with a number of clients developing embedded solutions 
based on the BBB. We've outlined the basic building blocks for many of the 
type of projects we're seeing being developed on our BeagleBone resource 
site Inspire 
- 
http://www.logicsupply.com/blog/2014/07/29/whats-new-inspire-latest-beaglebone-black-projects/

I hope your project has taken off in the last year.

 Hi,

 I am new to BBB, I have several questions regarding this.

 1. I currently develop industrial control systems using micro-controllers. 
 I would like to use the BBB for some of my control applications. I read in 
 the BBB home page that the BBB is a development platform, does this mean 
 this system can only be used for development and not professional or 
 industrial use ??

 2. Can the BBB be used for applications that do not require visual 
 interface like LCD or keyboards ? Like controlling a stepper motor, 
 accepting logic signals from external hardware ??

 3. A basic scheme I have in mind is, when BBB boots on power up, instead 
 of desktop or a command line begin loaded an application (code by me) will 
 be loaded, this application will then manage various tasks like monitoring 
 input ports, flashing some LEDs etc.

 Is the above scheme possible with the BBB ??

 Please be patient with me as I am new to embedded linux and to BBB..


 thanks

It's no longer triggered. Instead it's ran in single user mode on
startup: cmdline= init=xyz.

Thus it's much more reliable.

But much funner to debug.  You need a serial connection, and you need
to understand what it's expecting along with what it is doing.

Re: [beagleboard] Beagleboard-xm avaliability

They only sale though distributors so it is up to
the distributor to handle this.The idea of setting up a production line,
loading the parts to build one board would make the cost of this board
around $500. Orders would need to be entered by the distributors. I am not
sure any of them would be willing to order 1500 boards just so they can
sell you one board. It is basic supply and demand. If we have real demand
then we will supply.

 If you want one board ask around the community and see if anyone has one
to sale.

[beagleboard] RevC Web Browser when booting from SDcard 5/14/14 image

2014-07-30 Thread tdlivings

I downloaded the latest boot from SD card image(5-14-14 ) image and it 
boots fine.
I can Putty and WinSCP to it also.
The issue I am having is when I run the included web browser it will either 
open and
crash right away or will open an allow a couple of clicks and then it is 
gone.
I am not sure if it is crashing or hiding but if you keep trying to re-run 
it after a couple of
times it does not even open.
Also when I logged out after doing this it shutdown fine but when I tried 
to reboot the image
on the SD card was corrupt indicating missing modules

I re-imaged the SD card and it again boots fine and has same Web Browser 
issue

The Web Browser is Chromium on this image.

When I boot the flash emmc image that is on the board I do not see this 
issue with the Chromium
Web Browser I was able to get Cloud9 running.

I am booting with a mouse, keyboard and external monitor and networked to 
my home router.

Does anyone else see this issue

Thank's
Tom

Re: [beagleboard] Re: RIP Never Used BBB

But, our goal was as low a price as we can get. Adding a protection against
all the things that could happen means it would have to be water poof and
withstand 220 VAC on the input. That is more than $10 to $12.

Reading the manual and the wiki is free.

Since there are very few of you who have done this, why should the rest of
us have to pay the extra cost. I think there are less than 20 out of 150,000
boards shipped.

[beagleboard] analogy Gyro breakout help?

2014-07-30 Thread Brian Heckathorne

I'm having a heck of a time figuring out the Gyro-py breakout. 

https://www.sparkfun.com/products/11341

I have it hooked up in to p9_40, and I can't figure out how to get it to 
read correctly. I've searched and searched for info related to conversion 
or whatever is needed to read an analog gyro correctly. If anyone has some 
info on how to do this in bonescript please fill me in!

Thanks!

Re: [beagleboard] SHT20 I2C temperature sensor isn't detected

Maybe you need pull up resistors? The revision B of the Weather Cape also

 The datasheet says the address is 0100 (0x40).

 After sending the Start condition, the subsequent I2C

Re: [beagleboard] BBB Rev C: Debian: PureJavaComm/JNA test fails

2014-07-30 Thread slowjourney

Thanks suggesting Google!!  I would never have thought of that!!

Seriously though, I've been trying to solve this problem for 7 days now.  
And I've Googled everything I can think of.  Your first hit doesn't tell 
me anything I don't already know.  

I believe this to be some sort of permissions or path problem with my 
Debian setup. That's the reason the request for support is under 
Newbie/Debian.  I've tried all of the path stuff that Java expects.  I may 
have something wrong on the Java side, but I don't think that is the case.  
I was hoping that someone that has been successful with PureJavaComm on BBB 
would be able to point me in the right direction.  So, I'll wait and see 
what happens.

I'm sure to try and cover everything would cost a bit, Not sure why anyone

How hard/costly is it to fix something like reverse polarity or blown gpio?

Re: [beagleboard] BBB Rev C: Debian: PureJavaComm/JNA test fails

You might want to try libbulldog (http://www.libbulldog.org).

Here's an example:
http://libbulldog.org/bulldog/examples/serial-example/

It can do advanced Serial communication as well, but has not been tested 
on Debian. By advanced I mean settings things like setting parity, 
databits and stop bits. Maybe that is sufficient for you. 

But you'll probably have to tweak the Java side a little, I don't know if 
the Debian devices match the angstrom serial devices.

What I can say about the error, though, is, that you will also get it, when 
the binary format does not match your system.

 Sadly nope. As it's not my image, so the automated install-me.sh/etc

 But you can always build that kernel branch and install the kernel

of reverse polarity, it isn¹t cost effective to add the protection to each
board. For example, circuitco has shipped 177,000 BBB multiplied by $10
protection is $1,770,000. Less than 20 returned because of reverse polarity
at $55 each is $1,100. The solution is obvious. Gerald is very smart and he
knows what he is doing ;-) Users just need to be more careful.

[beagleboard] What are the 'dmidecode' and 'lspci' equivalents on ARM?

2014-07-30 Thread sudhir v

For no reason I want to just explore the system and its details. I came 
across this command 'dmidecode' which is supposed to dump all the hardware 
information. It did not work on BBB and I did some searching on google and 
on one of the ARM forums it has been mentioned that 'dmidecode' does not 
work on ARM systems and people over there were still discussing on what can 
be done regarding this. I do not want to dive too deep for now. All I want 
to see is details about the BBB. 
I have tried lscpu, lsblk, lsusb. Things that did not work were dmidecode 
and lscpi. Is there a way I can work around this?

Re: [beagleboard] Using SPI in a kernel module

2014-07-30 Thread liyaoshi

I mean you should follow the ifx6x60c driver struct . use tty driver as
general out and input .

Dont' use sys_open .




2014-07-30 17:14 GMT+08:00 nwk...@gmail.com:

 When I insmod ifx6x60.ko, its probe method isn't called either. Is there
 anything else I have to do?

 Actually , I have write a driver based on iMX6 and V850 , implement via
 tty driver .

 And suggest you follow kernel driver ifx6x60.c

 Subject: Re: [beagleboard] Using SPI in a kernel module

 Thanks, John.

 I Iooked at kernel/drivers/iio/dac/ad/5064.c

 There's the following struct which is passed to *spi_register_driver()*:
 static struct spi_driver ad5064_spi_driver = {
 .driver = {
.name = ad5064,
.owner = THIS_MODULE,
 },
 .probe = ad5064_spi_probe,
 .remove = ad5064_spi_remove,
 .id_table = ad5064_spi_ids,
 };

 I compiled the module and loaded it but the probe function never gets
 called. Why?

 From this I can see that this driver isn’t DeviceTree enabled so I’m not
 sure which SPI interface it is using. Either you can add the devicetree
 support to this driver so that you can specify which SPI interface to use,
 or e-mail the Linux-IIO mailing list and see how to use this driver.

 Regards,
 John

 Subject: [beagleboard] Using SPI in a kernel module

 Hello,

 I'm currently working on a kernel module which needs to communicate via
 SPI to an external microchip.

 I used the cape manager to enable SPI. The device is accessible through
 /dev/spidev1.0.
 But since it's a kernel module, I guess it's not recommended to access
 files via sys_open()?

 Another approach I found would be adding a struct to 
 *arch/arm/mach-omap2/board-am335xevm.c
 *and then use *spi_register_driver()* in my kernel module. But in my
 kernel sources (3.8.13) this file doesn't exist.

 There is no board files since the introduction of device tree.



 What would be the right way to use SPI in my kernel module?

 Look at examples in /drivers/staging/iio or /drivers/iio

 There are plenty of examples of using SPI calls in a kernel module.

 Use the power of GIT to find what you are looking for. In the Kernel
 source do the following:

 git grep spi_sync_transfer

 Regards,
 John

 Nils

Re: [beagleboard] Re: RIP Never Used BBB

This is something *anyone* should check. Always. But of course it doesnt
happen 100% of the time. Much easier than waiting x amount of time for the
new one to arrive, not to mention now you're out ~$60 US.

 John no worries my friend I hope you didnt take offense im a Texan to boot
 and was only thinking outloud. Wasnt implying anyone made a mistake or how
 smart they are or are not. Ive been quite surprised how on top of
 everything Gerald is. No doubts John hope you didnt take offense or think I
 was downing the product any. Was NOT the case. I think its a great product
 and cant wait to see whats next.

 Don’t worry so much, nobody gets too serious here. Gerald explained his
 thinking a while ago and I was just giving him a break because he is really
 busy working on his next project.

 Regards,
 John

 Personally I wish the support for bonescript was larger but that will take
 time.

 Subject: Re: [beagleboard] Re: RIP Never Used BBB

 I wasn't saying make it bullet proof, just some simple goof proofs. Like
 on the 5v plug, that kind of thing. I get the whole cost thing and by and
 large agree.

 I'm sure to try and cover everything would cost a bit, Not sure why
 anyone would be putting 220v to the 5v plug, but i could understand reverse
 polarity on the 5v plug. Not sure it needs to be gone to the extreme.

 How hard/costly is it to fix something like reverse polarity or blown
 gpio? if repairs are easy enough, perhaps protection isn't worth it.

 Think economics and not technical. Since there were very few returns
 because of reverse polarity, it isn’t cost effective to add the protection
 to each board. For example, circuitco has shipped 177,000 BBB multiplied by
 $10 protection is $1,770,000. Less than 20 returned because of reverse
 polarity at $55 each is $1,100. The solution is obvious. Gerald is very
 smart and he knows what he is doing ;-) Users just need to be more careful.

 Regards,
 John

 I think I would of paid 10 - 12 extra bux for a BBB that had some
 protection. Feels like at any moment my BBB might suddenly spontaneously
 contract magic smoke disease and all it's electrons fall out.

 Since there are very few of you who have done this, why should the rest
 of us have to pay the extra cost. I think there are less than 20 out of
 150,000 boards shipped.

 John

 hello people, please excuse my for my Tarzan English.
 first connect my BBB with a 5V supply 4A with the negative in the
 middle, might have killed her so easily?
 now with the positive in the middle got hot and nothing more happend.
