[beagleboard] Eclipse C and Remote Debugging
I have Eclipse Kepler running on Ubuntu 14.04 x64, I can build and remote debug Java applications on the Beaglebone Black, but for some reason I cannot remote debug C applications. I can compile a C application and I can see that it is transferred to the Beaglebone Black, I can even run it from an SSH terminal on the Beaglebone Black. But trying to remote debug always fails with a GDB error. The console reports that GDB will reconnect, however it never does. I've tried following numerous videos on YouTube, however none of them have resolved this issue. In the end I decided to build and compile on the Beaglebone Black directly, however now I get an error saying GLIBC_2.17 libc.so.6 not found...sorry if my post isn't very detailed, I'm at work now without access to all the information. Can anyone point me in the right location to resolve either the remote debugging or the GLIBC_2.17 error? I have already spent a very long time trying to find answers myself.

You need GDBServer installed on your BBB. You launch GDBServer on your BBB with IP of host and specify the port number for the host to connect to. In Eclipse, I don¹t recall the exact command, but it is something like gdb remote BBB ipaddr BBB port.

Re: [beagleboard] Eclipse C and Remote Debugging
Hi John, Thank you for the reply, perhaps I wasn't very clear. GDB Server is installed on the Beaglebone Black and I see the process running, it just fails to connect. I will post more detail when I get home tonight. I've tried using the default port 2345 and also found a post suggesting , neither worked.

Re: [beagleboard] Security when connecting autonomous BB to the Internet
A good term to google for is hardening a Debian server. There are many articles and several good books for people with various backgrounds.

Can anyone point me to a guide for what I should do to make the BB secure for long term autonomous connection to the Internet? Well, that's a difficult question. You connect it to the Internet so that it's capable of performing certain functions that you want, but you want to secure it so that it will not do anything that you don't want. The best approach, then, is to rigorously specify what's allowed and what's not, and implement controls that match this spec. You have several tools in your disposal: - you can set up an independent firewall in front of your device: if your device is on a home/ISP network you probably have a router that already implements that. - the BBB can run the Linux firewall (iptables) that control the network traffic into and out of your device - if your requirements can be met by your BBB always originating traffic, things are easier: both iptables and ISP router firewalls support outgoing connections out of the box, and your BBB is in control of the traffic. You have to pay attention to DNS---DNS spoofing is the principal vulnerability for this kind of setup - if you need to connect to the BBB from the outside, you want to limit the open ports and implement it in a cryptographically secure way, by using SSH/SSL/TLS or IPsec. This is tricky to get right, because there's always a possibility of vulnerabilities like Heartbleed -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

[beagleboard] sht15 kernel module
Hello, this is my first post here, so I hope I'm posting this in the right place. # Boring intro: I'm using the sht71 (see [1]) humidity and temperature sensor on the beaglebone. This sensor is supported by the sht15 kernel module. I adapted the sht15.c code to run in user-space using sysfs and it works. Not exactly a clean solution... How do I use the module directly? I'm using device tree overlays for another sensor (bmp085) and it works great. # The actual question: Is it possible to load the sht15 kernel module and pass the necessary platform data using device tree overlays? There isn't any info about the sht15 in the kernel under: Documentation/devicetree/bindings/ Does that mean that the module doesn't support the device tree overlay approach?

Re: [beagleboard] Re: Can the BBB get damaged due to a hard power down?
Sounds cool and easy to implement hardware-wise. Can you share the code for that? Something like this: // use plain old open to avoid any buffering etc int enablefd = open(/proc/sys/kernel/sysrq, O_SYNC | O_RDWR); int trgfd = open(/proc/sysrq-trigger, O_SYNC | O_RDWR); // enable sysrq write(enablefd, 1\n, 2); close(enablefd); // sync disks write(trgfd, s\n, 2); // remount ro write(trgfd, u\n, 2); close(trgfd); // poweroff system (/usr/bin/systemctl poweroff -f); exit(0); As I mentioned, I use full data+metadata journaling on the filesystem, not just metadata. The only issue is that the system doesn't restart if power is reapplied before the supercap is fully discharged. You have to wait 10 seconds or so before a restart is possible. I'm not sure how to fix that. - Mike -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

Another question is regarding the power using only the USB, is there any current restrictions during BBB boot up? because if i power some HW to BBB 5V (consuming about 150mA) the BBB does not boot. Well, the usb spec gives you only 100mA till you request more. So I don't see that design booting off a standard usb port any time soon.

Also no communication on outstanding units not delivered and RMAs From our own production we know that customer service tends to suffer when things run hot, but we still believe we deserve better.

Re: [beagleboard] Re: Commercial use of BeagleBone
Please correct me if I am wrong. At this point everyone involved in the development and manufacturing of the BeagleBone Black is doing so at break-even or a financial loss. This is an intentional strategy to build a critical mass of students, hackers, and hobbyist to create an ecosystem around the development system. This is a good long term strategy and a socially responsible position. Ideally, a healthy ecosystem will continue to grow around the TI based chip and the Circuit Co based board. The challenge comes, as we saw with power up and power down, when others expect a social responsibility project to meet their needs as a commercial product. Again, as I understand it, Circuit Co is at their maximum manufacturing capacity for the BBB. Everywhere I look, the BBB is sold out with-in hours of a distributor receiving a batch. Many of the distributors have agree to sell one per customer until the supply situation is resolved. Their goal, at this point, is to get as many units as possible into hands of students, hackers, and hobbyists to build the ecosystem of hardware and software developers who have a history of adding value back into an open project. This is new ground for many people and it will take a while for everyone to understand how the pieces fit together. The good news is that everything on the BBB is open so anyone is welcome to manufacture of modify it to meet their needs.

Re: [beagleboard] Using BeagleBone with JavaScript/Node.js
Irelandathome, I have personally installed Node.js from scratch and have had it working. On Debian before it was technically supported As said above, Bonescript runs on top ( along side ? Jason would know the best ) of Node.js. There is only one hurdle when compiling from source. You need to tweak the build script to build for the given processor type. Also, it seems many of the javascript developers for Node.js modules are oblivious to the concept of multi ARCH software. So, it may be wise if you're going to experiment on your own, that you backup your file system between each module install. At least this was the easiest way for me to keep a pristine ( clean ) file system. All the major module like Express as far as I can tell seems to work fine though. I did have a problem with one of the older package managers initially while I was figuring things out. NPM worked fine last I looked though. Also, you may not be able to use the latest version, but personally I got very close( about a month back from latest ). I have a command line log of the steps I took to achieve this if it's of any interest.

Also: 6.1.9.2 VDD_3V3A Rail The VDD_3V3A rail is supplied by the TPS65217C and provides the 3.3V for the processor rails and can provide up to 400mA. 6.1.9.3 VDD_3V3B Rail The current supplied by the VDD_3V3A rail is not sufficient to power all of the 3.3V rails on the board. So a second LDO is supplied, U4, a TL5209A, which sources the VDD_3V3B rail. It is powered up just after the VDD_3V3A rail. U4 is capable of sourcing 500 mA, but on-board it also powers nand, ethernet and uSD. Whatever is left for externals is less than 500 mA, 250 mA left as is documented seems reasonable.

Lithium Iron shouldn't be discharged below 2.7V. I'm not sure what happens to the battery charging circuit in the PMU, but my guess is that is will go to some sort of a lockout for safety reasons so Im not sure if the switchers can run from this energy source. Have you asked anyone at TI if it is OK to use the PMU like this? Perhaps you should post a question on E2E. If you are charging at 440mA, it will take 50 Seconds to reach full charge. What happens when the power fails before that 50 Seconds? I would recommend that you monitor the supercap voltage and wait until it is fully charged before opening any files. It is an interesting concept, but I'm still skeptical if this can really work.

The only issue is that the system doesn't restart if power is reapplied before the supercap is fully discharged. You have to wait 10 seconds or so before a restart is possible. I'm not sure how to fix that.

Re: [beagleboard] Cross Toolchain for Debian Wheezy
I use Robert's instructions from that kernel built from scratch instructions partially because it does make cross compiling very simple. All you have to do is match the Linaro toolchain. The Windows binaries for Linaro work fine too for what it is worth. Or at least did last I built from scratch. I wrote a mini howto setup LInaro + Code::Blocks on WIndows, and posted it on beaglefu forums last year. But it is very simplistic, and I probably need to revisit / rewrite the instructions. Mainly I just wrote it to share the gist of what was possible. Code::Bocks btw is a very flexible cross platform IDE, that isn't written in java. If that is important to you.

Re: [beagleboard] Re: Can the BBB get damaged due to a hard power down?
Batteries can be had that have a lifetime of 5+ years. Depending on the type of battery you use. Flooded lead acid ( for RE use ) can have a much longer life. Especially if the batteries are conditioned / charged properly. I've personally bought, and used 10,000 aH D Cells that have lasted 3 years, but failed eventually, because I was using them in a Maglite flashlight, and had dropped it many times. The point is, where there is a will, there is a way. Also, perhaps I am remembering wrongly, but I seem to recall reading that super caps have a limited lifetime as well. Something about only having so many charge cycles similar to a battery. On Wed, May 28, 2014 at 11:06 AM, Dr. Michael J.

Batteries can be had that have a lifetime of 5+ years. Depending on the type of battery you use. Flooded lead acid ( for RE use ) can have a much longer life. Especially if the batteries are conditioned / charged properly. You can buy Tadiran batteries that last 10 years, but they are expensive. They aren¹t real batteries either, they are a type of hybrid battery. http://www.tadiranbat.com http://www.tadiranbat.com/ I've personally bought, and used 10,000 aH D Cells that have lasted 3 years, but failed eventually, because I was using them in a Maglite flashlight, and had dropped it many times. The point is, where there is a will, there is a way. Also, perhaps I am remembering wrongly, but I seem to recall reading that super caps have a limited lifetime as well. Something about only having so many charge cycles similar to a battery. Not true. As long as you do not exceed their maximum voltage, supercaps charge cycles are 100x that of batteries and their life expectancy is 10 Years. You can also charge and discharge them much faster than batteries. Regular Lithium Iron are good for about 1,000 charge cycles and 3 year capacity is less than 80%.

You'll need to make sure the TS (battery temp sense) pin is at a proper voltage to allow charging. If the supercap does not have a temperature sensor, you can simply put a 10k resistor from TS to GND. If you are charging at 440mA, it will take 50 Seconds to reach full charge. What happens when the power fails before that 50 Seconds? I would recommend that you monitor the supercap voltage and wait until it is fully charged before opening any files. That is why I use full data+metadata journaling on the filesystem. If an unclean shutdown happens before the supercap is charged, the next boot-up will be delayed for several seconds as the filesystem is repaired using the full journal. That is annoying, but it is a minor cost for robustness. Mostly, the supercap is there to eliminate the need for the repair delay. It is an interesting concept, but I'm still skeptical if this can really work. Well, I do use it, so that's one data point. The other main alternative for bullet-proof power-fail robustness is to rely on on something like unionfs to provide a mix of read-only and read/write filesystems, but that's not so simple either. It's complex and not very well supported in general. Batteries have a fairly limited lifetime, so I don't consider that a practical solution (for me). I'm interested to hear how other people prevent corruption on power loss, though. - Mike -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

Re: [beagleboard] Re: Can the BBB get damaged due to a hard power down?
I was not saying the charge cycles were the same, just that they do not work indefinitely. Less than 10 years life expectancy IMHO is on par with lead acid batteries. Also, the batteries I used were 10,000 maH or 10aH ( not 10,000 aH ). For two they cost me ~$25, and they were very heavy for their size. We live completely offgrid and run our house completely off solar / a large-ish battery bank. I am not an expert per se, but have lots of hands on with this type of setup, but on a larger scale. You definitely would not want to lug one of these around to use with a BBB ( let alone 3 because they're 2v deep cycle RE's ). But the NiMH D Cells I have used in the past would probably work fine. They never corroded. Although the charge cycles is = 500 for the NiMH, which if they operate like lead acid. A charge cycle only counts once the battery is taken down below a certain charge %. Me, I'd definitely prefer to use a battery, mostly because I am very familiar with the characteristics of batteries, and writting code for an msp430 ( for conditioning a battery, and monitoring line voltage ) would be really simple. But again, I really have not spent a ton of time thinking about it.

Batteries can be had that have a lifetime of 5+ years. Depending on the type of battery you use. Flooded lead acid ( for RE use ) can have a much longer life. Especially if the batteries are conditioned / charged properly. You can buy Tadiran batteries that last 10 years, but they are expensive. They aren’t real batteries either, they are a type of hybrid battery. http://www.tadiranbat.com I've personally bought, and used 10,000 aH D Cells that have lasted 3 years, but failed eventually, because I was using them in a Maglite flashlight, and had dropped it many times. The point is, where there is a will, there is a way. Also, perhaps I am remembering wrongly, but I seem to recall reading that super caps have a limited lifetime as well. Something about only having so many charge cycles similar to a battery. Not true. As long as you do not exceed their maximum voltage, supercaps charge cycles are 100x that of batteries and their life expectancy is 10 Years. You can also charge and discharge them much faster than batteries. Regular Lithium Iron are good for about 1,000 charge cycles and 3 year capacity is less than 80%.

From http://e2e.ti.com/support/power_management/pmu/f/200/t/185514.aspx: The battery charger should work fine with a supercap. You'll need to make sure the TS (battery temp sense) pin is at a proper voltage to allow charging. If the supercap does not have a temperature sensor, you can simply put a 10k resistor from TS to GND. If you are charging at 440mA, it will take 50 Seconds to reach full charge. What happens when the power fails before that 50 Seconds? I would recommend that you monitor the supercap voltage and wait until it is fully charged before opening any files. That is why I use full data+metadata journaling on the filesystem. If an unclean shutdown happens before the supercap is charged, the next boot-up will be delayed for several seconds as the filesystem is repaired using the full journal. That is annoying, but it is a minor cost for robustness. Mostly, the supercap is there to eliminate the need for the repair delay. It is an interesting concept, but I'm still skeptical if this can really work. Well, I do use it, so that's one data point. The other main alternative for bullet-proof power-fail robustness is to rely on on something like unionfs to provide a mix of read-only and read/write filesystems, but that's not so simple either. It's complex and not very well supported in general. Batteries have a fairly limited lifetime, so I don't consider that a practical solution (for me). I'm interested to hear how other people prevent corruption on power loss, though. - Mike -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

Rather post your response just below the text you are responding to so everyone understand the context of your response. With that out the way, the order is determined by it¹s dependency.

Re: [beagleboard] Eclipse C and Remote Debugging
I remember someone saying that GDB for the BBB ( perhaps the whole ARCH ) Does not work properly. This was last year though. Which port are you using for the C GDBServer ? From what little you describe it almost sounds like a connection issue, because of too low a port, and a possible myriad of other things. Giving us the EXACT error message as given to you on the command line would certainly help *some* But as John said, you may want to consider moving to Debian just because most people are using it now, or will be.

Robert, I agree, but default it seemed the tools used in Angstrom are different and create more headache for people like me who have been using Debian for years. Many things like dropbear, instead of openssh-server for instance can be a PitA to get used to. Especially when you already have experience with other tools. Not to mention the fact that the whole Angstrom experience for me personally felt very shoddy. Needless to say Angstrom lasted about a week on my own BBB until i found your instructions last year. Been running debian ever since.

Re: [beagleboard] Where files per the Angstrom manual?
I would recommend that you upgrade your machines to the new Debian based release. I think you will find that there is more information about Debian than there is about Angstrom. The reason for the project moving from Angstrom to Debian is to allow developers to use Debian which is more common and better documented.

[beagleboard] Custom Beaglbone Black from Circuitco
I've been trying to talk to the people CircuitCo about building a run of the beaglebone black boards for a commercial project, but I can't seem to get anyone to respond to emails and the two people I have phone numbers for are always busy. My understanding was that proper etiquette was to not poach boards from the distributors if you build a device around the beaglebone and have them produced for you. I even spoke to someone at a CircuitCo booth at a conference last year (DesignWest - where the beaglebone black was launched) and they indicated this was common already for the original beagleboards/bones. I can't get anyone local interested in building them because of some of the minimum order quantities on some of the parts (like the emmc). Anyone at CircuitCo around? I have money and need around 100 boards made. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

There are plenty of things that get built and sold in those kinds of numbers, like specialized instruments. On Wednesday, May 28, 2014 3:33:49 PM UTC-5, Robert P. J.

Re: [beagleboard] Custom Beaglbone Black from Circuitco
100 boards is not a lot of boards. Especially when you have distributors screaming for 50,000 boards to fill their large POs..

Re: [beagleboard] Problems with updating Beaglebone Black via opkg install
Hi, you have to connect your BBB directly to the internet via the ethernet connector on the BBB. That was my fault...I only connect it over usb to control with command line and I got the same errors. So be sure that your BBB is connected to the internet.(I think tethering over usb is not possible) Maybe this might solve your problem...

I can connect to the links it provides, but I want to know why they aren't downloadable from the PuTTY. I am wondering if there is just a bad connection remaining between the BBB and my PC (Windows 7). I am still very new with the BBB, and learning more about it as I am interning. My main project while I work here circles around the use of the BBB, I just seem to be butting heads with it lately. I'd love to get some feedback about how I should go about fixing it. I am trying to fix it in order to create a web server through the BBB if that helps any in figuring out the issue.

[beagleboard] Cross compiling for Ubuntu 14.04
Hi, I can't seem to find a cross compiler for debian BBB that works (consistently) on Ubuntu 14.04 I'm using the latest debian image for BBB from beagleboard.org/latest-imageshttps://groups.google.com/forum/#%21category-topic/beagleboard/debian/mdd-Y7QsE8M . I'm running 64 bit Ubuntu 14.04. I've managed to make my programs run on Angstrom, but I've been failing for about a week trying to port to Debian. I tried the Linaro gcc at http://eewiki.net/display/linuxonarm/BeagleBone+Black#BeagleBoneBlack-uEnv.txtbasedbootscript and arm-linux-gnueabihf-g++ worked for most of my files. However, two of my files will compile and fail to run on the BBB. I enter: arm-linux-gnueabihf-g++ -Wall -Wno-unused-parameter -W -Wshadow -DARM_COMPILE -pthread -lstdc++ -lrt -o fileName $(SRCS) and when I run the file on the BBB (./fileName, like I did for the other programs that worked), I get: ./fileName: /lib/arm-linux-gnueabihf/libc.so.6: version `GLIBC_2.17' not found (required by ./fileName) What did I do wrong? Alternatively, is there a different cross tool chain? Sorry to take up your time, and thanks in advance for the help.

Re: [beagleboard] Where files per the Angstrom manual?
Completely agree with David. Angstrom seems to be a dead end, IMNSHO.

I think you will find that there is more information about Debian than there is about Angstrom. The reason for the project moving from Angstrom to Debian is to allow developers to use Debian which is more common and better documented.
