Re: [beagleboard] Re: command not found?
Hi Wulf Man, I don't know, is there a way to tell? Looking at what's inside there is no text script but the is ELF at the beginning so I assume its and exe? The suppliers told me eveusbd is the UNG daemon (starts with the system and is constantly running in the background), eveusbc is a command-line utility for controlling it. So you are probably looking for the latter. so again I would have assumed an exe? I uploaded and unpacked the .tgz file. I assume that only unpacks and doesn't install anything. I couldn't find any related processes running or anything in /systemd for startup but without an exact name I'm not sure. One this that seem clear from what they told me is: eveusbc is a command-line utility for controlling it.

[beagleboard] Re: Help with powering beaglebone black using VDD 5V pins
Hi, I think we are facing similar problems. Have you found out a solution? It came to my mind if there is some need to force a external reset or something... Or maybe we failing to apply signals to the gpio pins after sysreset goes up... I have a specific design to do that, but maybe it is not working as expected. Le lundi 20 juillet 2015 03:59:58 UTC-3, Mohak Bhardwaj a écrit : I am building a differential drive robot system and am using Beaglebone Black Rev C to run the software. I want to power my beaglebone using the VDD 5V (P9_05)and ground (P9_01). But upon connecting it to the power supply, my board is not powering up and none of the LEDs is blinking. Here are the specifications of the power circuit I am using: Battery: 4.4V LiPo battery ib series with 3.7V LiIon battery(current limiting circuit removed for increasing discharge rate) Regulator: HTC LM2576-5.0 with rectifier (IN4007) and capacitors The beaglebone makes a very light buzzung sound when connected to power but does not boot up. It is working fine when connected to my laptop via usb. The voltage regulator output is coming out to 5-5.5V. I found other topics where people faced similar problems but none of them answered the question conclusively. I have an amateur level knowledge of electronics and really need to get over this hurdle in order to get my project running.

Re: [beagleboard] push button on 7-inch touch screen to send some strings through the serial port.
Hi Henry, Did you ever get something going? I just received my BBB with Debian and 4D Systems 7 LCD cape. All I want my app to do is display a few soft buttons that control some gpios. I also want the BBB to boot into my app automatically at startup. I just downloaded QT Creator on my Win7 PC, and was hoping there's an example program that I can cross compile for the BBB and be off and running within a few hours. Does not seem like the case. Is cross compilation even possible from Win7 PC for BBB target? Ideally I do not want to use a uSD card with some other Linux version to make this work. I'd like to just send a binary to the BBB running the pre-installed Debian and have it work without much reconfiguring. If you or anyone else can shed some more light on this that would be much appreciated.

[beagleboard] PMW on P8.13 and P8.19 on Debian 8.1 / Linux 4.1.2-ti-r4
On a BeagleBone Black running Debian 8.1 / Linux 4.1.2-ti-r4
https://rcn-ee.com/rootfs/bb.org/testing/2015-07-19/lxqt-4gb/, I'd like
to be able to enable PWM on P8.13 and P8.19 using two different device tree
overlays rather that a single overlay.
The two overlays currently being used are show below. If the first overlay
for P8.13 is used, it will work correctly. If the second overlay for P8.19
is used, it will also work correctly. However, if both overlays are used at
the same time, only the first one activated will work correctly. The second
one will fail to function. I'd imagine the problem is related to fragment@2
in the overlays, but I can't figure out what needs to be done to make it
function correctly. Any help in figuring out how to solve the issue would
be greatly appreciated.
*Overlay for PWM on P8.13*
/dts-v1/;
/plugin/;
/{
compatible = ti,beaglebone, ti,beaglebone-black;
part-number = bot_pwm_p8_13;
version = 00A0;
exclusive-use =
P8.13,
ehrpwm2B;
fragment@0 {
target = am33xx_pinmux;
__overlay__ {
bot_pwm_p8_13_pins: pinmux_bot_pwm_p8_13_pins {
pinctrl-single,pins =
0x024 0x4
;
};
};
};
fragment@1 {
target = epwmss2;
__overlay__ {
status = okay;
};
};
fragment@2 {
target = ehrpwm2;
__overlay__ {
pinctrl-names = default;
pinctrl-0 = bot_pwm_p8_13_pins;

};
};
};

Re: [beagleboard] PMW on P8.13 and P8.19 on Debian 8.1 / Linux 4.1.2-ti-r4
Anyway, this is the project I speak of, and it should be preinstalled on
beagelboard.org debian images.
https://github.com/cdsteinkuehler/beaglebone-universal-io
The readme.md is about all I know on the subject, but in a couple cases
I've seen Robert use it wildly different from how I've seen it used
previously. e.g. to load device tree overlays, and configure pins in a way
I had not seen before.

Unfortunately, I'm not very familiar with the tool, but at least two

Robert, is there a user manual for Universal IO ?

Re: [beagleboard] Re: BBB not working well with Mac Yosemite
jdmarshall, What problem is that? Why don't you do this. Make a new post, and be *very* explicit / verbose as to what you've attempted to do. One thing I do know though. Is that there is a Mac utility that has to do with DHCP, or something that is completely whack on OSX mountain lion I believe, that was causing g_ether to fail. Not just for the beaglebone black, but for *everything*. SO perhaps this is related. Passed that, the only advice I can give you is to use a virtualbox Linux virtual machine, and develop on that. I do not use OSX personally, but do use virtual machines quite extensively when prototyping code for the BBB. Not because my OS ( Windows ), and communicate with the board, but because Linux development is best done on Linux, and not developing code natively on the BBB keeps me from ruining the onboard, or sdcard flash media . . .

[beagleboard] Debian 8.1 lxqt 2015-07-19 4DCAPE-43T touchscreen issues
I'm running on a beaglebone black rev B using the micro-sd standalone version of Debian Linux beaglebone 4.1.3-bone14 #1 Thu Jul 23 00:04:37 UTC 2015 armv7l GNU/Linux The touch mouse is very erratic in this release. During the calibration routine the mouse jumps about. The touch will result in the mouse bouncing from the approximate touch point to a random point, in a flickering action. Releasing the touch causes the mouse to rest in a random position. After calibration, the touch screen is still not calibrated. Touching on a clickable item on the screen will result in the same weirdness, the mouse will jump form the uncalibrated touch point to a random position and back in a flickering motion. The touch seems to be a right click instead of a left click, or an all-click (not sure because sometimes you can get the menu to pop up). It is difficult to get the menus to respond to the mouse events. Anyone have ideas on how to get the touchscreen to behave properly? -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

Re: [beagleboard] PMW on P8.13 and P8.19 on Debian 8.1 / Linux 4.1.2-ti-r4
The goal is to update a tool called bot-io https://github.com/fivdi/bot-io to function with the 4.1 kernel. Among other things, bot-io allows pins to be configured to use drivers that beaglebone-universal-io doesn't support like gpio-keys and gpio-leds, so beaglebone-universal-io can't be used. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

Re: [beagleboard] PMW on P8.13 and P8.19 on Debian 8.1 / Linux 4.1.2-ti-r4
Brian, for what purpose ? The reason why I ask is that the config-pin
utility should be able to achieve the same end goal, and is a userland tool.
Unfortunately, I'm not very familiar with the tool, but at least two people
on the groups here should be able to guide you in this respect.
Robert, is there a user manual for Universal IO ?

to be able to enable PWM on P8.13 and P8.19 using two different device tree
overlays rather that a single overlay.
The two overlays currently being used are show below. If the first overlay
for P8.13 is used, it will work correctly. If the second overlay for P8.19
is used, it will also work correctly. However, if both overlays are used at
the same time, only the first one activated will work correctly. The second
one will fail to function. I'd imagine the problem is related to fragment@2
in the overlays, but I can't figure out what needs to be done to make it
function correctly. Any help in figuring out how to solve the issue would
be greatly appreciated.

Re: [beagleboard] push button on 7-inch touch screen to send some strings through the serial port.
*I just downloaded QT Creator on my Win7 PC, and was hoping there's an example program that I can cross compile for the BBB and be off and running within a few hours. Does not seem like the case. Is cross compilation even possible from Win7 PC for BBB target?* Cross compiling QT can, and will be quite a daunting task for the inexperienced. I can tell you that I have experience in several programming languages, and compilers since around '93, and I'm not sure I could do this. Or if I could, I know it would be a difficult task. Honestly though, short of the possibility of someone already having gone through the process, who frequents this google group. This question is best asked of the QT project maintainers. That is, for the QT specific questions. As for the rest . . . Toggling GPIOs should not be too hard to do. I have not done this myself to date, but there are many blog post on the web covering the subject. Using SYSFS, mmap, and bonescript, just to name 3 ways. *Ideally I do not want to use a uSD card with some other Linux version to make this work. I'd like to just send a binary to the BBB running the pre-installed Debian and have it work without much reconfiguring. * So you propose writing a binary for an ARM + Linux target on Windows ? This *may* be possible, but really is asking for trouble. Let me clarify. I use Windows on a daily basis. All my desktops run some form of Windows from Win 7 on up. Having said that, I would not *dream* of doing the above. Perhaps dream is also the wrong word. Nightmare would be more like it. Hate to burst your bubble, but if you want to develop for the BBB, running Linux. You're going to have to learn, and use Linux as a development tool. It may take some time sure, but that is nothing compared to the troubles you're very likely to run into when developing software on Windows for the BBB running Linux. Just for starters: If you run into a problem that is specific to a Linux API / library. How would you know what to look for ? *OR* How would you even use the linux-header files for your specific kernel? Anyway, it is not impossible, but trust me it is more headache than it's worth. That, and you'd probably be spinning your wheels indefinitely, when instead you could simply setup a Linux machine in hardware, or virtual machine, and be long done with all that. *If you or anyone else can shed some more light on this that would be much appreciated. Thanks.* On Sun, Jul 26, 2015 at 10:11 AM, Frank Rizzo david.kucharc...@gmail.com wrote: Hi Henry, Did you ever get something going? I just received my BBB with Debian and 4D Systems 7 LCD cape.

other users) does not by default execute files in the current directory.
This is for security reasons if I'm not mistaken. This can be bypassed by
typing the relative or full path to the command, such as ./eveusbc . Since
that doesn't work, it is worth looking into another important difference
with DOS:
- Linux systems have more extensive file permissions than the original
DOS system. It could be that the eveusbc file does not have execute
permission. You can check by 'ls -l', which shows the permissions in a
format such as rwxrw-r--. There are three groups, identifying permissions
for owner, group and world (from left to right). Each group can have
r(ead), w(rite) and execute permissions. To excluse any problems in this
area, you can give all permissions to everybody by 'chmod 777 eveusbc' and
then try again './eveusbc' .
By the way, 'chmod 777' is not necessarily the best way to keep a
computer secure ;-) but it should help determine whether the problem is
related to permissions.

Hi Peter,
Yes I'm logged on as root but I'm in the directory where the file is.
Does this not work the same as DOS?
I tried typing ./eveusbc but I just get No such fie or directory
I must say I'm lost.
Any ideas?
Thanks
Ian

From the prompt it seems you are logged in as root and usually root
does not have the current directory in it's path for executing commands.
Best regards,
Peter
