[beagleboard] Re: Here is the BeagleBone Debian (beta) image you want to test
I recently tried running some OpenCV code that works fine independently but crashes with a select timeout error when I try running it while I have my mini wifi module from Adafruit plugged in to provide wireless access via an AP network. Both the camera and the wifi module are plugged into a usb hub. I've done some research online and it sounds like the Bone's USB DMA support might not be up to the task. I've read about using other kernels and was wondering what was built into this image. I also read another post about including NEON: http://blog.lemoneerlabs.com/3rdParty/Darling_BBB_30fps_DRAFT.html#x1-6000doc Is that optimization already built into this image? Anyone have any other ideas for getting the Beaglebone to handle both a cheap USB camera and WiFi module, or is this something that would be better handled by the Raspberry Pi B+? I like controlling motors directly from the bone with the handful of PWM pins it sports, but wireless debugging is a little higher on my priority list so I can move to a Pi and an Arduino if necessary. -- 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: Here is the BeagleBone Debian (beta) image you want to test
I purchased a proto cape from sparkfun with an eeprom. Apparently I can write a dts file and compile it so that I have better control of the headers at boot time. I'm trying to control some dc motors and was only able to find 4 gpios and 4 more pwms that are low and stay low when the beaglebone boots. I can use those for now, but I imagine that in the future this will probably change and I'd like to know how to deal with it. I'd also like to be able to choose my pin layout so that it's a little more intuitive for my students. So my questions are: 1. Can I access and program the eeprom on the proto cape from the beaglebone black? If so, how? 2. How do I make the dts file? 3. How do I compile it? 4. Where do I put it? 5. How do I make debian use it when it boots? -- 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: Here is the BeagleBone Debian (beta) image you want to test
I was using the March 31st image (I think) up until yesterday when I updated to the most recent image. One thing I liked about the march image is that it automatically booted to the sd card (no need to press the boot button). How can I implement this functionality with the newer image? -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

I'm still running into some annoying root/debian user permissions problems. First, I have to switch to the root user in order to run a script I wrote to share the host computer's Internet connection. Second, when I push to git I get an error message about permission denied. The push goes through okay, but I don't know how to go about fixing whatever is causing the error. Below is a screen shot of my terminal that shows exactly what I'm doing. https://lh5.googleusercontent.com/-MbMTeKPhBsA/U0GK5wa8x7I/AHE/0VQ0LkDZdBA/s1600/Git+Error.PNG -- 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: Here is the BeagleBone Debian (beta) image you want to test
Yes and no. The solution was worse than the problem. Updating to the development kernel as mentioned above resulted in better support for Wifi but an unstable LXDE environment. At this point I just don't rely on Wifi. On Friday, April 4, 2014 9:03:12 AM UTC-8, Toni Salaet Larrull wrote: I have the same problem... You could solve it?

Re: [beagleboard] Re: Here is the BeagleBone Debian (beta) image you want to test
My BeagleBone part of a primitive robot with a breadboard strapped to the top, and servo motors underneath. The wifi dongle was between both. For this reason, I dug out my unpowered USB hub and used it as an extender to get the wifi dong'e away from all the metal. I powered the beagle bone with an external power supply and remoted into it via usb. I was able to get the Adafruit dongle to connect to my secured home network 1 out of three times this time around as well as a secured hotspot hosted by my phone. This was better than the netgrear wna1100 which was only able to connect to the secured hotspot (not my regular home network). Neither was able to connect to an unsecured hotspot. Attempts to connect via wifi also seem to cause the BeagleBone to freeze up frequently. Any ideas? Also, it would be really handy if the default user was root (like on Angstrom) so that I didn't have to type sudo su before most terminal commands. This would also allow me to open files more easily. I'm guessing this would also allow the user to reboot and shutdown the beaglebone, options which are missing from LXDE at this point, and which cannot be execute from the command line using the debian user. -- 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: Here is the BeagleBone Debian (beta) image you want to test
I downloaded and tested the March 27th image today. Thanks for including xrdp-it made testing wifi go much faster. Here's what I found. - I was able to connect to a WPA2 secured network at the school where I teach - I was unable to connect to my cell phone when unsecured (Android portable wifi hotspot) - I was able to connect to my cell phone if I secured the connection (WPA2 PSK) - I was unable to connect to a WPA2 secured network at home - One of my students was able to connect to the WPA2 secured school network, another was unable to connect - The students that was unable to connect to the school network was also unable to connect to my cell phone (secured as well-didn't try unsecured) - I was able to create an ad-hoc network (at least I think it did because it showed up in Wicd) We were all using the tiny Adafruit dongles and tethered to BeagleBones via USB. Whenever we were unable to connect, we could see the connection-it just timed out when trying to get an IP (unsecured networks) or authenticating (secured network). Any ideas? I also tried setting up an ad-hoc network. It showed up within Wicd, but I wasn't able to detect it with a computer, my Android cell phone, or an iPhone. Is ad-hoc working for anybody else? Given the inconsistency, I'm guessing the problem is hardware (the dongle), so I ordered a few of the Netgear WNA1100 dongles. Should have them in a couple of weeks. Also, looks like the eMMC version doesn't have Wicd functioning out of the box.

Sad to say that I had my wifi dongle working yesterday, but despite hours of effort today, I was unable to get it working.

Re: [beagleboard] Re: Is normal Network Routing supposed to work in USB tethered mode?
I have spent a lot of time trying to share a Mac's Internet connection with a BeagleBone Black while connected via USB. I am able to do this without any difficulty just using the Mac Gui on a machine running OSX 10.6.8. On a machine running OSX 10.7.5, I can make it work, but I have to run the following commands on the host: - sudo su - ifconfig en3 192.168.7.1 (where en3 is the BBB's interface) - sysctl -w net.inet.ip.fw.enable=1 - sysctl -w net.inet.ip.forwarding=1 - natd -interface en1 (where en1 is the interface for the Mac's Internet connection) - ipfw add divert natd ip from any to any via en1 This is all I have to do if I'm using my older Linksys router or if I'm tethered to my cell phone, but if I use a newer Netgear router, then I have to enable Internet Sharing through the GUI as well. If I download and install Mavericks OSX 10.9.2, I cannot share Internet when using the Netgear router, but I can share Interent when the Mac is tethered to my phone (haven't tested this with my Linksys yet). At Any rate, it looks as though sharing a Mac's Internet connection using the commands above is dependent on the network. I would love to see a method that works no matter what kind of network the Mac is connected to. FYI, I'm using the Jaoshua Wise's latest RNDIS driver (rel5). -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.
