Re: [beagleboard] BBB = RPi + Arduino (combined) ???
The beaglebone(s) are a completely different class of embedded system compared to the Arduino. In short, the Arduino *may* be able to do 1/100th of what the beagelbone(s) can do. Hell, the two PRU's ( Programmable real time unit ) can do any one thing the Arduino can do up to ~10x faster. For your suggested use case, the Beagelbone(s) are also better than the rPI. The rPI is better suited for media type stuff, such as playing video, etc. At least one caveat here. There is much more to learn when using an embedded Linux system. Be it rPI or Beaglebone. if you have Linux experience you have a head start on this. Anyway, your question is rather general . . . I would suggest you pick up reading material for the beaglebone on the web, and perhaps take in a video or two from youtube, On Wed, Dec 3, 2014 at 8:34 PM, rjc2827 bobthecass...@gmail.com wrote: I've programmed business systems for years, and now I want to get into controlling (and reporting on) related mechanical systems.

[beagleboard] Large number of timer interrupts after kernel upgrade (3.8-bone to 3.14-ti)
Having upgraded to the latest TI kernel, I noticed a large number of timer interrupts. From itop: INTNAME RATE MAX 57 [ 10.ethernet] 6 Ints/s (max: 7) 58 [ 10.ethernet] 6 Ints/s (max: 6) 84 [_timer] 10203 Ints/s (max: 10230) Seem to get a consistent 10KHz set of interrupts from _timer (on an idle system). Booting with the 3.8-bone latest kernel does not show this behaviour. Also rather confusingly this behaviour seems to be non consistent, in that I have a pretty much identical bone running the TI kernel that does not seem to have the same problem: INTNAME RATE MAX 57 [ 10.ethernet] 8 Ints/s (max: 8) 58 [ 10.ethernet] 6 Ints/s (max: 6) 84 [_timer]35 Ints/s (max:37) Anyone any idea what is going on here ?

There is already the answer: your module has the wrong format. Where does it come from? What module is it? Does it belong to the kernel version you are using? Is it really an ARM-HF-module?

Re: [beagleboard] BBB = RPi + Arduino (combined) ???
This is only my opinion. If you are new to either linux, or gpio programming in particular. I would get a RPi first. The Pi is meant to be educational. And has a TON of stuff on the internet about it, from a free monthly magazine, to books, to just a lot of info on the internet. While the RPi is very useful (much more so than the Arduino -- in fact I regularly translate Arduino code into Python for running on my Pi), it has no native A/D pins. The BBB has far more capability in every way you can think of. I intend to make a SDR radio soon on mine. Anyway, learn something easier first. Learn linux, and learn gpio programming in general. Then step up to the BBB. Jerry On Thu, Dec 4, 2014 at 1:19 AM, William Hermans yyrk...@gmail.com wrote: The beaglebone(s) are a completely different class of embedded system compared to the Arduino.

[beagleboard] BBXM HDMI issue on ubuntu-14.04.1 with LXDE
Hello All, I've just completed a fresh install of: ubuntu-14.04.1-console-armhf-2014-10-29 on a BB-XM rev B.

Re: [beagleboard] Re: how to make pwm_P8_13 low on boot?
Hi Jan, I had another look at this, was able to replicate what you are seeing, and think I know what's going on.. The part-number 'bone_pwm_P8_13' is already included in the kernel build. I'm not really sure of the mechanics, but when doing a build from the git repository, all the .dts files in the /firmware/capes folder get compiled to individual .dtbo files, and from there into object files, and then combined into a single built-in.o file. The end result of this appears to be that putting an overlay file for one of these built-in part-numbers into /lib/firmware doesn't achieve anything, it just doesn't get read (even if you increment the version). Anyway, it's an easy fix - once you know what's going on!! You should just need to change the part-number to something else unique (and the file name to suit), and then the options can be set in your overlay as you'd expect.. Hope this helps, Jon. On 26/11/14 10:11, janszymanski12...@gmail.com wrote: Good idea, thanks. I will try it. I think the positive pulse will be so short that it will not be able to move the motor. On Wednesday, November 26, 2014 8:29:31 PM UTC+11, Jon E wrote: I'm not sure about that. Jan said before that it's only driven high after loading the PWM driver, and the processor datasheet shows ball T10 (P8_13) as driven low during/after reset. Jan, not ideal, but to disable the output sooner you could load the overlay through cape manager, and then write 0 to the run parameter immedately afterwards. But I still think the correct approach is to look at the devcetree/driver code and see why those parameters are having no affect..

Re: [beagleboard] Re: how to make pwm_P8_13 low on boot?
Jon, Thank you for your valuable input. I will try it soon and let you know. The obvious question already is which one will take precedence in loading: the overlay defined in the kernel or the one handled by the cape manager? Cheers, Jan On Friday, December 5, 2014 5:34:44 AM UTC+11, Jon E wrote: Hi Jan, I had another look at this, was able to replicate what you are seeing, and think I know what's going on.. The part-number 'bone_pwm_P8_13' is already included in the kernel build. I'm not really sure of the mechanics, but when doing a build from the git repository, all the .dts files in the /firmware/capes folder get compiled to individual .dtbo files, and from there into object files, and then combined into a single built-in.o file. The end result of this appears to be that putting an overlay file for one of these built-in part-numbers into /lib/firmware doesn't achieve anything, it just doesn't get read (even if you increment the version). Anyway, it's an easy fix - once you know what's going on!! You should just need to change the part-number to something else unique (and the file name to suit), and then the options can be set in your overlay as you'd expect.. Hope this helps, Jon.

Jan said before that it's only driven high after loading the PWM driver, and the processor datasheet shows ball T10 (P8_13) as driven low during/after reset. Jan, not ideal, but to disable the output sooner you could load the overlay through cape manager, and then write 0 to the run parameter immedately afterwards. But I still think the correct approach is to look at the devcetree/driver code and see why those parameters are having no affect..

[beagleboard] LCD4 Cape Overlay Goof?
There seems to be a problem with the LCD4-00A1 cape overlay. The
overlay includes support for four buttons, while the actual board seems
to have five, and one of the four GPIO pins configured in the overlay is
*NOT* actually used by the hardware (per the schematic).
Before I send in a patch, it seems like this would have been identified
and fixed before now. Am I just missing the proper overlay somehow? I
am building the kernel using the scripts from (tag 3.8.13-bone68):
https://github.com/RobertCNelson/bb-kernel/tree/am33x-v3.8
Details:
Per the schematic
https://github.com/CircuitCo/BeagleBone-LCD4-RevA1/blob/master/BeagleBone-LCD4-RevA1-schematic.pdf
The hardware buttons are:
Button : Pin : GPIO
---+---+-
Left : P9.15 : GPIO1_16
Right : P9.23 : GPIO1_17
Up : P9.16 : GPIO1_19
Enter : P9.24 : GPIO0_15
Down : P9.30 : GPIO3_16
...but in the DTS (from tag 3.8.13-bone68) I see:
exclusive-use =
Only 4 GPIO pins for buttons, and one of them is wrong
(P9.21, gpio0_3)
bone_lcd4_cape_keys_00A2_pins:
Same as above (only 4 pins, and one of them is wrong)
gpio_keys {
Is correct...lists 5 buttons with the proper gpio pins

Re: [beagleboard] eMMC flashing suggestions
nope, there is still something missing. the client USB port does not identify itself by lsusb from the connected laptop. I am getting power from this port, but no usb bbb device identification. I am happy to start over, but I don't know where. I want to flash a working debian image to my beaglebone blacks, rev B and C, with 2GB into the eMMC. console is fine---I don't need X. the 7.5 img.xz doesn't seem to work for me. I can't flash it. the 7.7 img.xz works, but now seems too basic (if it is just designed for flashing); and even with the above steps, I can't seem to get the client USB ident to work. actually, this is probably the last step I need. after getting the USB client magic (id, usb mass storage, and usb networking) to work, I would be operating a non-magical linux device that I could handle myself. (in someone else's port, I think you mentioned that the usb was not working, but the 1a70b1cb550bd8d0bf4f2c0d43e72cba image had this fixed already.) I think the RootStock-NG.sh and your .conf file are part of a (complex?) toolchain to build img.xz files. alas, I don't know this toolchain. looking at http://elinux.org/BeagleBoardDebian#Demo_Image, the only .img.xz file I saw that flashes the eMMC is: BBB-eMMC-flasher-debian-7.7-console-armhf-2014-10-29-2gb.img.xz robert---I know you are already doing a lot here, so please forgive my audacity: may I suggest offering a 7.7 .img.xz eMMC flasher that has the usb client port already working? if not, what steps need to be taken for the bbb USB client port to identify itself as a device to the connected desktop USB host? regards, /iaw -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

*The Pi is meant to be educational.

You do not need to know *everything*, just everything that applies to your situation. Most things are a few hours away from achieving, once you understand Linux, and perhaps a bit of a google session.

RE: [beagleboard] xeno_16550A driver install on Debian 3.8.13-bone67
Hello Cédric Sorry, but I had to give up my ambitions due to time pressure. I ended up using the standard UART drivers in the Debian environment. If you are in the same application situation as me, you may consider using standard Linux drivers: I am implementing a sensor platform where the sensors each issues hardware interrupts that marks the time of measurement. Sensors are: GPS (1Hz), Barometer (1Hz), Gyro-/Accelero-/Magneto-meter (4Hz-8KHz), Inertial platform (200Hz), SwarmRadio (10Hz?). UART: GPS + SwarmRadio I2C: Barometer + Gyro-/Accelero-/Magneto-meter IMU: SPI After each GPIO interrupt the data is collected by UART, I2C and SPI. The most important rea-time task is to relate the hardware interrupts (i.e. the collected data) to a common timer. I managed to do that by writing kernel RTDMs for the interrupting GPIO-lines. The sensor tasks issues blocking reads towards the RTDMs that sends the timer-value from the interrupts. The tasks then uses the standard Linux drivers for collecting data. So far, the only driver causing marginal situations is the SPI driver in combination with an Inertial Measuring Unit (IMU). This sensor operates on 200Hz, hence I have to collect its data within 5ms. The IMU uses 16-bit transfers, but require the chip-select to go in-active for at least 2us between each transfer. This cannot be handled by the standard SPI driver an forces me to generate separate 16-bit transfer calls to the driver. Each call gives a 20-30us kernel/user-space punishment and a very jittering total transfer-time. Bottom line (for me) is that I have to cope with the standard Linux drivers for the time being. I am now running tests on all interfaces and the only sensors that misses interrupts is the SPI-bus. I am not sure how degrading these standard drivers is for my real-time requirement, but I hope to reveal this by some long-term testing. At the moment I am part of the under-wood and must rely on the patient support from the tall trees (Gilles and Robert). If time allows later on, I will look into the possibilities of doing some work on the drivers. First driver to get my attention will be the SPI driver... Bon chance!

Pour utiliser le pilote 8250, vous aurez aussi besoin de modifier le fichier * .dts.

Why is the ttySx still there and the 8250 by default enabled in the -bone67 ? The history goes like this.. Back in the board era, omap used the 8250 driver, then new non-generic features where added enabling omap features, thus making the omap-serial driver. Then came device tree's.. First the omap-serial driver got it's dts bindings and all omap devices used them. In the background, 8250 got some more generic enhancements and generic dts bindings... Fast forward the 8250 now has even shinny-er better features then the lagging omap-serial driver.. Thus it was decided to move back, in a release or two.. That ^ may be childlish, but it's the condensed version of pages and pages of discussions on linux-omap Regards, -- Robert Nelson http://www.rcn-ee.com/ -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to a topic in the Google Groups BeagleBoard group.
