Re: [beagleboard] Rev C processor in adafruit website - AM3359 ?
All rev C boards have the AM3358 processor.

So I just bought a new BBB and I purchased it from adafruit. I noticed that the website says rev C will have AM3359AZCZ100 processor but my board has AM3358BZCZ100 on it. Is it just a mistake while advertising? (This could be the case since they clearly mention 1GHz and 2000MIPS) Thank you, Sudhir Processors are identical other than support for EtherCAT Slave.

Well, considering the fact that it will take a whole new processor and a totally new design, I would say yes it will be more than the current $55 price. Right now it can do 1920x1080 @ 24FPS.

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] 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.

After I set pin P8_11 to HIGH, the solenoid clicked and its power led turned on, then the BBB died. I tried turning the BBB power on again, but all that happens is that the power led flashes briefly. I had checked everything w a multimeter before hooking up the system. The solenoid is 177 ohms; hooked to 24V, it reads 0.151A -- which is under ULN2003AN's .5A max and matches its datasheet (AVS-5322-24D on http://www.automationdirect.com/static/specs/nitradirectionsolenoidavs5.pdf). There shouldn't be a problem. And the ULN2003AN isn't broken. The BBB and transistor worked fine for a more expensive solenoid valve (VUVB-L: http://www.festo.com/net/SupportPortal/Files/17267/Ventile_en.pdf). I've tested it with that valve and the multimeter read 374 ohms; hooked to 24V, it reads 0.062A. I don't understand why the BBB died. It shouldn't have because I was careful about checking the datasheets and then w the multimeter. Would someone please tell me what went wrong?

Last week it was working but today it appears to be completely dead. I tried using three different methods to power it up, USB from a PC, USB power from a USB phone charger that I have used in the past to power the BBB and a 3A 5V wall wart through the barrel jack. None of those power sources will even illuminate the power LED between the Ethernet jack and the barrel jack. It's as if the PMIC is dead or was somehow zapped. I have tried pushing and holding the power button but nothing. The power light does not even blink or flash. Between last friday and today I have not touched it though a coworker had to move my board to use my desk. It was not connected to any power source so it couldn't have been shorted. My only guess is ESD. But the bigger problem is I have lost 4 solid days of work as it is all on the eMMC and I forgot to backup (my dumb fault). My only hope is if I can back feed the SoC power from the headers therefor bypassing the PMIC. But from the looks of the schematics and manual, the SoC depends on the PMIC to control the reset and power signals. Am I looking at a total loss or is there any hope of powering the board or reading the eMMC? -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

Re: [beagleboard] Using Relay Module With BBB
I can't tell much from a picture. Doe sit have a schematic, or a link to one? If the relays are 5V, then you cannot drive them from a GPIO as it is 3.3V and delivers only about 6mA.. Connecting 5V will blow the processor. You would need a level shifter such as a transistor to drive the relay..

Re: [beagleboard] Upgrade to Rev C?

What are the pros/cons of Rev A vs Rev C outside of the extra 2GB of memory? Any thoughts?

Re: [beagleboard] Can I Disable Touch Screen Sampling on an Internally Generated Event?
Real solution is to fix the issue. You just asked how to trigger a shutdown which was my answer. That would not be my solution.Shutting down a touchscreen for x amount of ms will be tough to do..

Is there just a port, or a named pipe, or some shared memory location that you can write to to briefly disable the touchscreen? I can imagine that it wouldn't be too difficult to shut down a driver, or tell X-Windows (forgive me, I'm not very BBB literate just yet having barely used one so far so my terminology may be off) to stop using it for long periods of time. I'm just wanting to shut it off a few milliseconds before turning on our EMI generator and turn it back on a few seconds after that. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

Re: [beagleboard] Commercially using the REV C?
there are no restrictions to using the board in commercial products as long as you understand that the board and the SW will change. Long-tern support of the HW and the SW is not guaranteed in its current form. In other words once we make a change to the board and it is say rev D, then we no longer make the rev C. 1) Find a distributor that will sell you the quantities you need. 2) The design is Open Source. Change it as you see fit. 3) Change it as you want to. No rules against it. 4) rev C will be supported as normal. But, we will not accept dozens of boards into RMA because the board was used in away it was not designed for. All support is community support 5) Warrant is the same except for #4 above.. I did not design the board for your application. So, I cannot guarantee that it will work in your application. You are totally responsible for that. I will not change the design to fit your application or needs. 6) For the HW, did you look at the System Reference Manual?

Then came Radio Shack, filling their stores with Make's Getting Started with BeagleBone kit. Then the Christmas rush. Then the Georgia Tech massively open online course on control of mobile robots hosted on Coursera. We had a couple of small production boosts, but haven't been able to make any dent in the demand.

Our desire is that people using the boards in products work directly with a contract manufacturer or distributor to enable boards builds to be planned out in time and with terms and conditions that won't hurt BeagleBoard.org's ability to supply classrooms, hobbyists and professionals building prototypes. Still, if distributors show stock, I expect people building products to continue to chew up some of the board supply. While these people building products are certainly sucking up a lot of boards, it is clear they aren't the only source of the high demand. Some of our distribution partners, most notably Adafruit and Special Computing, put quantity limits of one board per customer on their orders to help keep supply going to individual makers. I took a look at Adafruit's website while they were showing some sock and observed board disappearing at the rate of about 2-3 PER MINUTE. One tweet from me and they were sold out again. This all leads to the obvious conclusion: we need more capacity. To accomplish this, we are taking a multiple prong approach of increasing capacity at CircuitCo as well as bringing on an additional manufacturer. These two prongs are summarized below. Prong #1 - Ramping up production at CircuitCo Ramping up production costs money. More test equipment is needed. Orders on various parts must be accelerated. Additional staff must be hired to run additional shifts. CircuitCo has been fantastic at taking the risk for us, but the margins for BeagleBone Black aren't the friendliest for them to take on these additional costs.

Feedback from different people, especially Adafruit, tells us this will improve usability in the largest segments of our community.

Re: [beagleboard] What are the safe power-down methods?
Pushing the button momentarily should power down the board if the SW supports it. If it does not, then it needs to be fixed. It does work as far as I know on the image we ship with the board.

Clearly pulling the power is not. Pushing the power button momentarily does nothing. Documentation says that software is needed to sense and respond to this action. I presume this means that said software is not part of the Angstrom distribution that shipped (before the switch to Debian). Pushing and holding the power button does cause a power down. Question1: Is push-and hold of the power button a safe shutdown method, or is it similar to just pulling the plug? Question2: If push-and-hold is not safe, has anyone (and distro) developed the software necessary to sense a button push and initiate a safe power down? -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

The Arduino collects data from environmental sensors placed around our house, and among other functions, is set up to dump the data from the sensors over serial. I'm planning to have the BBB connected to the Mega over serial to collect the data, store it in a database, and notify me via push messages should something go out of the ordinary. However, I'm concerned about blowing up the BBB, since there are a lot of caveats about making sure that things are sequenced properly and that no power is applied to the BBB inputs before it's ready. I know that the Arduino outputs 5v signals, and the BBB can only handle 3v3, so to address that, I've built a logic converter board based off of some ZVNL120A mosfets, following Phillips' App Note AN97055. My big question is - what's the best way to prevent damage to the BBB? Should I add some extra mosfets inline with the rx and tx lines, and control the operation of the mosfets from the BBB (so that when the BBB is off, the serial connection to the Arduino is disconnected)? Or is there some other way that I should handle this?

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] Can the BBB get damaged due to a hard power down?
This is why there is a power button. I suggest that you go to your PC and yank the power cord. Whether it is running Linux or Windows, I suspect it won't like it. If you can't use the power button, then yes you can design a cape that will let it gracefully shutdown properly. When I designed the board I felt that a button was less expensive that all the other stuff you would need to put on the cape. Not to mention the small form factor of the board made it tough to fit all that onto the board. And yes, in a small number of instances, we have seen that yanking the power may cause damage to the processor because the PMIC does not have enough time to power down the processor in the correct voltage sequence.

The beaglebone will bootup and shutdown occasionally while the primary processor will be on all the time.

With I2C pulled up by default and assuming I did attempt to drive the SPI bus when BBB is powered down, is that going to destroy the processor? -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

Re: [beagleboard] Beagle Bone power sequencing and power states
It depends on what you plan to do with the DDR state and if you want to preserve it. I have never tired it, but it should be possible. You need to look at the datasheet for the TPS65217C for the power sequencing and power down modes available.

If this is the case then the need for an external RTC would seem nil. where can I find more info about the power sequencing of the bones? The SRM shows the order in which the rails are sequenced but which rails are powered up and down for various states of shutdown, sleep, and suspend, and how to reach those states with the bone is what I'm looking for. where can I find this info? what power states are presently supported?

Yes, REV C is the only one we will make. We will not be making old revisions.It is right to say that REV A and REV B are no longer available from us.

Does it mean that for bulk orders (we think of 1,000 or more pieces) there is no real plan how to go ahead? Of course, we would need a more or less reliable delivery slot.

Assuming the image you are running has it. The latest image does have it. After it powers down, then you can remove the power. We need to make sure the PMIC powers down all the rails to the processor in order. Or you can enter “halt” on the console or terminal window and it will power off.

Re: [beagleboard] beagle bone dc power connector
The proper size is listed in the SRM. Maybe the ones you are are not exactly to spec. Same connector we have used for what, 6 years now?

The SRM says, 2.1MM center positive x 5.5mm outer barrel but a number of connectors I have that state 2.1x5.5mm will not mate as they are to large outside diameter and they measure 5.5mm OD as stated. A 5mm OD connector seems to fit just fine. What is the proper size? Is the SRM in error or did maybe some of these boards get built with slightly off sized DC power jacks?
