[beagleboard] Re: porting kernel 3.13.6 to beaglebone black
Though I'm not sure on the current linux distro you are using on BBB, my choice is Arch Linux and it already has 3.13.6 kernel. I managed to install run on my BeagleBone Black(yes, arch linux), however, this version of kernel does not have cape manager (/sys/devices/capemgr.*) and I cannot figure out how to change/apply device tree file. In short, 3.13.6 is already ported to BBB, and there is no capemgr (unlike 3.8.13).

Re: [beagleboard] Hardware watchdog for BBB
I am still not sure why anyone would need / want all this complexity. Living offgrid, powered by solar panels which charge a battery bank, which then powers our home via an Inverter . . . I am not sure why the same concept can not be used on the BBB. 1) Power the BBB via a small rechargeable ~5V power source. 2) charge this ~5V power source via AC mains, solar power, whatever. 3) Monitor power on the charge input, and when absent send a message to the kernel to shutdown / hybernate. Then, all you need is to make sure your power source can work a few minutes with no input power applied. Perhaps even double this value for safety. The way I see things, there is nothing to complex about all this at all.

You really need to monitor the input power supply and the state of the kernel to determine when to remove and reapply power to the BBB. You have to consider the corner cases such as: 1. power failure could occur during the boot up sequence 2. power failure occurred, triggering a shutdown sequence and then power is restored during the shutdown sequence.

Currently there is no external info to determine the state of the kernel so you would have to add a kernel driver which will control a GPIO to signal when the kernel is in a safe mode (all volatile info written to non-volatile memory) and also monitor a GPIO used to interrupt the kernel when a power failure occurs. So now, you need an external state machine which tracks the input power supply, state-of-kernel and charge state of super caps. Timers are also required to ensure a proper power recycle. I hope I have covered everything you need to consider in your design, but perhaps others has some insights I haven't considered.

The way I see things, there is nothing to complex about all this at all. Not a problem when you are there to push the on button or reset your BBB when it locks up. What happens when there is no human intervention and the BBB is in some remote location? What happens during brown outs, power surges, power fluctuations, auto reclosure operations, power bypass, etc? What happens when you have 10K, 100K or even 1 Million devices running. Even a 0.1% failure rate will be a disaster. Cost is a primary factor so you cannot spend 10x on the power supply (batteries, solar panels; really?). Batteries are expensive and have a limited number of charge cycles, typically less than 1,000 cycles (less than 3 years). Actually, the circuit is even more complex because supercaps have a max voltage of 2.5 or 2.7 volts, so you have to stack them. Now you need an energy balance circuit to make sure all caps in series maintain an equal charge. During power fail, the voltage across these supercaps decrease, but you need to maintain a constant voltage, so you need a boost switching supply. The switcher cannot start until the supercaps have a minimum charge. I could go on, but yes the complexity is necessary to ensure a reliable supply. Your solution may be perfect for your requirements, but I think we are talking about a different operating environment.

Re: [beagleboard] HELP. dead beagleboneblack
If Power LED still lights up, that means no short happens. JTAG header has two reset signals: nSRST (system reset) and nTRST (JTAG reset). I believe one of these two pins must be connected incorrectly. You might try to dis-soldered the header first and see whether the BBB can work then. 2014-03-24 1:52 GMT+08:00 dd ddlawre...@rocketmail.com: Hi. I bought BBB A6A new, 1 month ago. It worked OK out-of-the-box. I power it from the USB from a windows laptop and poke around with a browser. No problems. I soldered on the proper JTAG header very carefully and now it is dead. The Power LED lights up, but nothing else happens. I am handy with electronics, programming and linux. What can I do to troubleshoot the BBB? Is there a DIY procedure?

Re: [beagleboard] Why is a SN74LVC1G06 connected between emmc and AM3359 on Beaglebone black?
To insure that on power up, the eMMC is not held reset which would result in you not being able to boot from the eMMC because it was in reset. The purpose of the device is to invert the polarity of the default state of the processor pin. If you look at the datasheet for the processor, you will see that the default state of the pin is low on power up.

I really like the 2014-03-19 image. It solves most of the problems I was having with Ubuntu and Angstrom.

This will make developing and debugging an autonomous robot that uses computer vision infinitely easier. I do have a few ideas for making the image slightly better. First, any chance you can install xrdp? This would allow my students to remote into the BeagleBone without having to access the Internet? Second, if I remember correctly it looks like the version designed to run from the SD card lists wlan0 within Wicd, but the eMMC version does not. IAny chance you can list wlan0 within Wicd for both versions? Third, I had to input the passphrase into Wicd, generate the PSK using wpa_passphrase, and then add the PSK into Wicd. Not sure why. Maybe I'm doing something wrong, but I suspect it's some sort of glitch with Wicd. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

Re: [beagleboard] Hardware watchdog for BBB
What happens when you have 10K, 100K or even 1 Million devices running. Now we know where all the BBBs went! For home use I've rigged two BBBs together so that each can monitor and reset the other. Every 5 minutes each board tries to send itself a message via an ssh connection to the other board. If it fails to receive that message, it assumes the other board has crashed somehow and sends a reset. If it still fails to get a response it carries out a power cycle. In conjunction with a simple UPS such as the OP describes, this would probably be enough for normal use. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

Now i want to use it in my home as a VOIP gateway, i saw that there is an asterisk port ( http://www.beaglebone-asterisk.org/ ) that seems to be pretty cool. For this i need to interface my SIM (I2S) with the BBB, is there an I2S GPIO and drivers for it available? I've saw some projects but they all use the chan_dongle or something like this.

[beagleboard] Secondary power button
I have installed MAME on a BBB and would now like to us it in an arcade cabinet. To keep the BBB hidden away in the cabinet I will need to wire a secondary power button. I have found tutorials on adding a button using the IO pins, but none that would work as a full replacement of the onboard power button.

[beagleboard] Re: Ubuntu nptdate can't find servers on boot
Solved! (Partly) I'm on a Windows domain, and it has it's own time server of course. That was blocking access to any external time servers. However, while I can now do ntpdate from the command line with the local time server ip specified, I have to kill ntp first since it is using the same socket. I think this issue have been discussed in the past and I can probably find the answer with enough googling, but if someone wants to share the recipe that would be great.

2. Download the pre-built Angstrom image from Chipsee
http://www.4shared.com/rar/8lKQ5nSBba/prebuilt-angstrom-bbb-exp-2014.html
3. Extract the pre-built Angstrom image somewhere.
4. Copy the 'boot' folder from the Angstrom image to the SD Card and
replace any duplicate files.
5. Plug in the SD Card and boot up.

think you can flash to the eMMC unless you edit the uEnv.txt

Re: [beagleboard] Trying to make flash install of my customized Beaglebone Black
I know that you did say this was for Debian, and as stated before I'm using Angstrom. Any things you can think of that would be gotchas? For instance the location of uEnv.txt is in /boot, not /boot/uboot. So I'm adapting the script, but creating a /boot/uboot subdirectory to copy and place the zImage, initrd.img and any other files. What I've also run into is that Angstrom doesn't have update-initramfs, so I was figuring to install that; it requires that I reconfigure from private network to DHCP and run opkg. But wondering if I'd be heading down a bad direction by trying to adapt that script if it really would match my intent but the intended system is different enough that the details need a lot of changes.

BBB wouldn¹t work for my application but I do draw from Gerald¹s brilliance ;-) For home use I've rigged two BBBs together so that each can monitor and reset the other. Every 5 minutes each board tries to send itself a message via an ssh connection to the other board. If it fails to receive that message, it assumes the other board has crashed somehow and sends a reset. If it still fails to get a response it carries out a power cycle.

[beagleboard] Did my Beaglebone Black died completely?
I got a Beaglebone Black from Adafruit last Friday, have it for a couple days, but I think it's dead now. On arrival, the ssh and everything work fine, however, the hdmi port does not work. I verified this later with another Beaglebone Black that arrived which work on the same equipment. Just today, I was doing some prototyping work, remove the BBB usb from computer while leaving it run on DC power. After a couple minutes, I found that the all LED on the board is off. I tried rebooting, nothing happen. The power LED only give me 1 blink when I press the power button / plug in power, then nothing. Maybe I corrupted the memory? So I try to flash a new OS with a microSD card, plug in power while holding the boot button. No luck with that either. It wouldn't even start the flashing process. It just give me one blink in the power LED and that's it. So is my Beaglebone officially dead? =( Kinda a bad first experience with the product... -- 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: Ubuntu nptdate can't find servers on boot
On Debian, what I did was make an init script to add a route to out gateway/router, and then called ntpdate in the same script right after. With Debian, you can order when these scripts ( services ) are run so they can be run during whichever time you prefer during the boot up process. In my own case, I just ran the script/service at the end of the bootup process. With all that said, Debian uses a different ( default ) system-v type init daemon than Ubuntu. Ubuntu uses Upstart, which as I understand is similar but different. I have done enough reading to realize that using Upstart on Ubuntu could be made to do the same thing, but I have no practical hands on personally Anyway, this is just one way I have figured out to do this one thing. While most definitely it is not the only way, and possibly not even optimal. But it worked for me..

[beagleboard] MMC1: strange voltage values in MMC1 module pins DAT[3-0], WP and CMD
Hello, I built a board really similar to beagleboard rev4 from scratch.

Re: [beagleboard] MMC1: strange voltage values in MMC1 module pins DAT[3-0], WP and CMD
Well, not much to go on here. A schematic would be extremely helpful. Configuration of pins are taken care of by the internal ROM and are shown in the datasheet. I would also look at your boot pins, but i have no idea where they are connected to.

Re: [beagleboard] Hardware watchdog for BBB
Yeah after I thought about it, after making my post I realized I did not include a way to bring the BBB back up. For bringing the BBB back up after input power is back up I suppose I would use an MSP430 to monitor the input power, and a keep alive signal from the BBB to the MSP430. A Value line MSP430 such as the MSP430G2553 is low cost ( ~$2.5 in quantities of 1 ) can run off a single button cell for years. the MSP430G2553 also has SPI, I2C, GPIO's, and UART, as well as a few other niceties( hardware WDT, and Timer(s).) So perhaps more complex than I originally led on, but perfectly doable, and not really all that complex. Just off the top of my head, I would use either a regular timer, or perhaps even use the hardware watchdog timer to cycle a reset on the BBB through a GPIO. With the keep alive signal being sent out over either SPI or UART. Is this on track with what you had in mind, or are you thinking of something else, or is this too complex for your application ?

[beagleboard] Re: Encouragement for the disencouraged
My only real issue that I have no idea what the Angstrom is really capable of and what really comes with it. I think the biggest hurdle for people is they have some embedded mindset with talk of processors and whatnot. Think of this as it is, a resource limited general purpose Linux computer in a small form factor. You develop for it just like you would a normal desktop computer. Don't think of it as what Angstrom is really capable of because Angstrom has nothing to do with it. Install Debian if you want and you'll be able to accomplish the same (maybe with less free RAM) using almost identical code. The biggest hurdle I had was to do things right the Linux way, as in using the abstracted to infinity drivers and sysfs interfaces to do something like access a single register for some hard ip. You can go bang registers and be done with it, but the whole point is that you don't have to care about the specific platform if you use the standard interfaces allowing you to port your code to some other future embedded (or not) system. 2 ranty cents for you.

Re: [beagleboard] Hardware watchdog for BBB
Hi John, Yeah, the MSP430G2553 can go down to at least 1.8v, and I am thinking a good bit lower. I am thinking perhaps 1.2V at minimal clock / periph's( I'd have to read the datasheet again ) Now just because I am relatively new to embedded devices, and I know the MSP430's fairly well, I would choose these for myself. The MSP430 value line products can not beat or even meet that price by a long shot in small quantities. I think the lowest my buddy got a tube of 10 for ~$1.35 each a bit over a year ago. One or two off, personally I think this price is fair enough. I haven't heard of the devices you're linking to, and the link doesn't work for me. So i can not even look to see exactly what it is. I would assume the MSP430G2553 would be overkill by comparison, feature wise. So, I am not much of an EE, but my buddy is. Perhaps I could get him to design something up while I'll tie things together in software. This is something I personally have interest in as well.

Re: [beagleboard] PRUSS and accessing ADC registers on Beaglebone Black
Did you find how to enable ADC without device tree? I have the same problem like you.

I manage to access it after enable ADC using 'echo BB-ADC /sys/devices/bone.capemgr.*/slots' . Though I could only do it in kernel 3.8, later kernel (3.12) gives an error saying symbol ocp could not be found. I do not really know how to change the .dts to get it working . Anyhow, I will work with 3.8 for now. There is no cape manager in V3.12 Regards, John Sincere, Nhan Nguyen On Wednesday, February 19, 2014 2:57:31 PM UTC+1, Charles Steinkuehler wrote: On 2/19/2014 7:43 AM, Nhan Nguyen wrote: Hi everyone, I have been trying to use PRU to read multiple ADC inputs. Unfornately, I am stuck at accessing to the ADC registers (chapter 12 on AM335x technical reference manual). I set the OCP registers, checked the PMAO registers on PRU to ensure access to external host. For example, I read the ADC REVISION as below: (tried to write to STEPCONFIG and STEPENABLE, etc.) MOV r13, 0x44E0D000 //ADC REVISION LBBO r5, r13, 0, 4 SBCO r5, C28, 4, 4 //store REVISION to shared memory to show with C program .. but everything returns 0. I install Ubuntu 13.04 on Beaglebone Black, tried kernels 3.8, 3.12. PRU worked with shared memory accessing, and GPIO1 registers (I am not sure what to try next) . I haven't tried it on the official Angstrom image, because I still couldn't get PRU to work right away on it. I suggest you remove the PRU from the setup temporarily and try directly reading the memory from C. This will be a lot easier to debug, and the PRU has no chance of reading ADC values if you can't read them from the ARM. As a guess, I suspect you don't have the ADC hardware setup properly and are getting bus faults when reading. This will show up as an error if you try to read the memory location from the ARM (making it easier to debug). Make sure you have loaded a device tree overlay that enables the TSC hardware (Touch Screen Controller = ADC) and populates an appropriate state-machine instruction table to digitize the values you are interested in. Unlike simpler microcontrollers, each major subsystem in the AM335x can be powered up or shut down, and by default most systems (ADC, PWM, etc) are powered down with their clocks disabled until you explicitly enable them. Once you can properly read the values from a raw memory location using the ARM, the PRU should be able to read them as well. -- Charles Steinkuehler cha...@steinkuehler.net -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.
