Re: [beagleboard] DVI on original BB Rev. C3
RobertCNelson: Oh, I just need to remember to dig out one of my old C4's and bring it to work. Does your latest commit (https://github.com/RobertCNelson/armv7-multiplatform/commit/96bfe9ba5050cfad338cf9d0966ed8c91a5d) contains any fixes regarding this issue? As far as I see no, or?

The I/O supply has to be there. If it's not turned on then it's 0 volts isn't it? Power supplies don't go open circuit when they're turned off so the 3.3 volt line will be sitting at close to 0 volts and you'd need to pump a lot of current into it to drag it away from there. There will be 10k or more of series resistance in the inputs so we're only talking about less than 1mA of current going through the clamping diodes, that's not going to move the supply line voltage by anything much. Look, go ahead and ignore me if you like. But I talk to the designers of this device daily and support hundreds of customers daily. And I see boards come into the RMA department all the time with blown processors due to this issue. The power sequencing diagram is there for a reason due to the multiple voltage rails inside this device. Violate the power sequencing and you will have issues. I'm not violating the power sequencing, I'm obeying it carefully by ensuring that there's no voltage on the inputs until the 3.3 volt I/O supply appears. -- Chris Green · -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

You've misunderstood me, I'm going to clamp to the BBB's 3.3 volt I/O supply. The suggestion made above was to use the presence of the 3.3 V supply on the BBB to Enable / Switch the external supply On, or conversely the absence of the BBB 3.3 Volt supply removing or disabling the external 3.3 Bolt supply. Has this made it clearer ? I do hope so, I hate it when the Magic Blue Smoke escapes from a chip :-( That's a possible way of doing it but I don't like the extra complexity, it's another way for things to go wrong. If that 'logical' connection between the BBB's 3.3v IO supply and my external supply goes wrong then the inputs get fried. I prefer simply using the BBB's 3.3 IO supply *directly* (with a diode of course) to clamp the inputs. We're talking about very small current here, I'm aiming to have 10k (or more maybe) series resistors in the inputs so the current through the diode even with a 3.3 volt difference between input signal and BBB input it's only 300 microamps or so. -- Chris Green · -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

It is not possible to have a fully deterministic real-time operating system on a processor that uses instruction/data caches. ie you have to turn off the cacheing to achieve determinism and eliminate performance jitter (which then degrades the average performance). Yep, but, that's the easy part. How about pipelines and instructions reordering done by the compiler and the processor? How about interrupts? How about multi-cores? How about the drift of the crystal you use as the clock source of your CPU? You might be shocked now, but as you can see it's impossible to have a hard real-time system with state of the art (multi-core) processors. Is it? I think that you need to come up with a realistic test suite to see if preempt-rt (with or without CPU isolation) is good enough, or if you need Xenomai (still you will see issues if Xenomai and Linux use the same caches), or some dedicated hardware like PRU. There is also some interesting work by Jan Kiszka - not yet on ARM.[1] I think there is some confusion about what real-time really means. It doesn’t mean fast or even consistent, it just means that it will respond to some event in a required time. If your requirement is that something respond in 1 second, then Linux kernel is good for real-time. If you want a response of less than 1ms, then the Linux interrupt latency may not meet this requirement. Remember, latency tests are conducted when the processor is under load. Xenomai running on the BBB can achieve 50uS interrupt latency whereas preempt-rt is more like 200uS.

[beagleboard] Confusion
Hi, I have two areas of confusion regarding the BBB. I'm new to it and Linux. I loaded the Ubuntu 13.04 image onto the board eMMC and it works really well. I want to know what the advantage of running it from the SD card would be? I see in some posts that people seem to prefer this. With a background in pics and basic arm boards it seems to me to be better to have the operating system running in hardware on an embedded system. My second area of confusion is regarding the uEnv.txt file in the /boot/uboot folder. There seems to be a number of posts on this, all with differing approaches. I've been working with device tree overlays and can add then to the SLOTS file manually. I want them to be loaded as the board boots, but adding e.g. campmgr.enable_partno=BB-UART1 to the uEnv.txt file in /uboot has no effect. I tried mkdir /mnt/boot mount /dev/mmcblk0p1 /mnt/boot nano /mnt/boot/uEnv.txt from the Adafruit tutorial, but this had no effect either. I assume someone must have an answer to this, or at least a link to explain it.

[beagleboard] Re: Using SPI/PWM/I2C/GPIO with Android on BBB
Accoding to your guidelines i downloaded the source from following webpage http://downloads.ti.com/sitara_android/esd/TI_Android_DevKit/TI_Android_JB_4_2_2_DevKit_4_1_1/index_FDS.html and downloaded source link from there http://downloads.ti.com/sitara_android/esd/TI_Android_DevKit/TI_Android_JB_4_2_2_DevKit_4_1_1/exports/TI_Android_JB_4.2.2_DevKit_4.1.1.bin the source successfully gets executed and a directory is created in same folder. chmod a+x [filename] in a terminal, or by right-clicking on the file in nautilus and going to propertiespermissions and check allow executing fils as program. Then open up a terminal, and cd to the directory you saved the file to, and type in the name of the file to execute it. This will bring up a user agreement, you must scroll to the bottom by pressing enter to scroll to the next line, then type I ACCEPT at the end. Careful, if you scroll too fast, you will be pressing enter when the I ACCEPT prompt comes up and the terminal will exit without doing anything. After you type I ACCEPT and press enter, the downloader will start and you will find your source directory in the same directory you downloaded your file to. But when i open the created folder its empty so I am unable to navigate to th said folder. I am working on beaglebone and will be using SPI interface. I will be workin on android. After you have the source navigate to /kernel/Documentation/ and you will see directories for ACPI, SPI, I2C, etc, (I dont see directories for PWM or GPIO but there is a gpio.txt and pwm.txt that seem to have the information for those interfaces, respectively). For SPI the file you want appears to be /kernel/Documentation/spi/spi-summary. hope this helps... https://lh4.googleusercontent.com/-908Hx3_H8Z8/UwwmbZkKwcI/AHE/5DrHKGu4iy8/s1600/post2.JPG Please do provide a feedback on the same I have attached the image of the open directory below https://lh5.googleusercontent.com/-2dnJzN_Y_Pg/UwwmFAvsfQI/AG8/1_RKuV204kM/s1600/post.JPG -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

stuck and when I gave ifup wlan0
this time it got the correct IP and was able to ping..

[beagleboard] 3G USB Modem issues
I've been seeing that a 3G modem I bought (Huawei E3131B) has been giving me some problems with the BBB. Firstly, it sometimes picks up the modem and powers it (light on modem flashing), but then somehow loses contact with it, and the modem no longer functions properly and is not picked up. Second, my Angstrom hangs sometimes when I plug the modem in and out and when I run programs such as ppp which are meant to connect it. My best guess is that there is something wrong with the USB driver. How would I go about debugging this?

Re: [beagleboard] Re: (Resource temporarily unavailable)Error while reading ADC pins
The ADC kernel drivers throw errors when reading multiple channels, you can either deal with it or fix the driver. So far, I've just dealt with it, ignoring the resource unavailable error and just continuing on: Python code example: https://github.com/cdsteinkuehler/linuxcnc/blob/MachineKit-ubc/configs/ARM/BeagleBone/BeBoPr-Bridge/ReadTemp.py#L303 The resource unavailable error is thrown in a consistent pattern, but the pattern changes depending on which channels you're actually reading. Also, the errors are not time sensitive. I get the same patten of errors when performing reads by hand (using cat at the command line, with _seconds_ between reads) as I do reading via a program with a 50 mS delay. I'm hoping they finally fixed this in the newer kernels. On 2/23/2014 11:01 AM, Ben Mitch wrote: Hi guys - have any of you reached a resolution on this?

[beagleboard] Re: How to turn on/off GPIOs in BBB
Sorry the first file's name should be gpio.cpp.
The code I have posted is based on the code at the following link:
https://github.com/majestik666/Beagle_GPIO/blob/master/Beagle_GPIO.cc.
I have attached my files(gpio.cpp and gpio.h) and hope it could help you.
One thing I want to remind you is that in my code I added the following
system(echo 5 /sys/class/gpio/export /dev/null);
system(echo 65 /sys/class/gpio/export /dev/null);
system(echo 105 /sys/class/gpio/export /dev/null);.

[beagleboard] AM335x Pinctrl Addresses
I'm trying to configure a board very similar to a Beaglebone Black to work with a 24-bit LCD panel, but to do this I need to configure all 24 LCD data pins to operate as LCD drivers. I was planning on accomplishing this using device tree overlays within my Linux environment, but I'm not really sure how to implement this specifically. I'm using the BB-BONE-LCD4-01-00A0.dts overlay as a reference, which configures lcd_data0 through lcd_data15 to drive an LCD.

Re: [beagleboard] AM335x Pinctrl Addresses
All of the LCD pins are listed in Derek Molloy’s nice BeagleboneBlackP8HeaderTable.pdf. The high-order ones you are looking for are on P8_11 to P8_17 + P8_19, but the order is mixed up. Do a web search for BeagleboneBlackP8HeaderTable and BeagleboneBlackP9HeaderTable and you will find Derek’s tables on github.

Any help would be appreciated. The authoritative source for register values can be found using the AM335x data sheet (Chapter 2, Terminal Description) and the AM335x Technical Reference Manual (Chapter 9, Control Module). The LCD signals are all listed in table 2-10 of the data sheet, with links to the package-specific pin, which gets you the pin name you can then look up in section 9.3 of the TRM Control Module Registers. There is a handy crib sheet available as well: https://github.com/selsinork/beaglebone-black-pinmux/blob/master/pinmux.ods ...which lists all the pinmux modes for each P8/P9 pin, and provides control register offset values for the pinmux control register. You may have to adjust by 0x800, as some code wants the register offset from the base of the control module register space (ie: 0x800-0x9ff) while other code expects an offset from the first GPIO pinmux register (ie: 0x000-0x1ff). Make sure you use the proper value. -- Charles Steinkuehler char...@steinkuehler.net -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

Re: [beagleboard] Interfacing htu21 over i2c with Beaglebone Black
I decided to give up on Angstrom and move to Debian using Robert C. Nelson's images/scripts. On kernel 3.13, I'm able to access this driver and read temperature and humidity. However, the temperature reading is at least 10F too high. I don't have another calibrated humidity sensor to compare this against. I've kept the pull-up resistors onboard (i.e. I haven't desoldered them). Could that be the problem?
