[beagleboard] TheCoolTool SandyBox Announcement
I am proud to announce that we where able to release the first version of the SandyBox mini computer: http://www.thecooltool.com/en/accessories/details/sandybox/ The SandyBox brings the whole Machinekit (http://www.machinekit.io/) experience to all major desktop OS (Windows, Linux, OS X) without the hassle of setting up a BeagleBone or computer. The first release is primarily focused on our UNIMAT CNC series (http://www.thecooltool.com/en/products/unimat-cnc/). However, we are interested in bringing the plug and play Machinekit experience to all people with parallel port based CNC machine setups. Therefore, we are looking for people interested in porting their parallel port based CNC machines to Machinekit using the SandyBox. Feel free to contact me if you are interested. Future features will be new QtQuickVcp based user interfaces (http://blog.machinekit.io/2014/11/new-qtquickvcp-interfaces.html), WiFi support and support for controlling machines using a Android or iOS tablet. Furthermore a 3D printer using the SandyBox as controller is currently in development (https://www.youtube.com/watch?v=LQrrJkjHjiU). The SandyBox would not be possible without the help of the BeagleBoard community, thank you very much for the excellent cooperation.

Re: [beagleboard] i2c-bus - A new Node.js I2C module
Sure, here are a number of things that come to mind: - All methods have asynchronous and synchronous forms (i2c has the synchronous form although it looks like it has the asynchronous form) - It offers more complete support for the SMBus protocols (quick command, send byte, receive byte, write byte/word, read byte/word, I2C block transaction (I2C block transaction are not part of the SMBus specification)) - It supports plain I2C (see methods i2cRead, i2cReadSync, i2cWrite, i2cWriteSync) - It offers runtime information about the functionality supported by the bus/adapter (like 'i2cdetect -F 1', see methods i2cFuncs and i2cFuncsSync, see example https://github.com/fivdi/i2c-bus/blob/master/example/i2cdetect.js) - One i2c-bus object can handle multiple devices - Because it supports the SMBus receive byte protocol (see methods receiveByte and receiveByteSync) it's possible to scan for devices (like 'i2cdetect -y -r 1', see example https://github.com/fivdi/i2c-bus/blob/master/example/i2cscan.js).

Re: [beagleboard] CE and ESD, BBB is failing 4kV contact discharge ESD testing
Thanks for the prompt response Gerald. The beagle has been designed into a system which is in a plastic and metal enclosure. The only I/O it has to the outside (other than touchscreen) is 2 USB connections. These connections are what are prone to the 4kv ESD. A discharge on the shell of the USB connector causes the micro to reset. This occurs even though ESD suppression has been designed in at the USB connectors. The micro seems particularly prone to this phenomenon. ESD is an awkward problem to solve, there isn't one solution to fit all and things such as enclosure design can have an influence...

Re: [beagleboard] CE and ESD, BBB is failing 4kV contact discharge ESD testing
You need to make sure that there is an earth ground on your power supply. The case of the USB connectors go to the common point ground, which is a zero ohm resistor by default to the DC ground input.

Re: [beagleboard] Enabling ttyO4 with DTR/DSR/RTS without the capemgr
Make sure the ttyO4 driver is loaded via the device-tree (use the dtb-rebuilder if needed), and setup the pin multiplexing with the installed-by-default universal overlay. The intent is to provide user-mode control of pin multiplexing so you should be able to enable just the Rx/Tx pins or whatever combination of data and handshake pins are needed for your application. Hello Charles, I am about in the same situation. As far as I have understood the installed-by-default 'universal' overlay is bound into the Kernel. Am I right? In that case, I see that the one bound into Robert's latest builds is intended for BB-Black, and exports all pins that are not HDMI and not eMMC. Also right? However, I want to run the 3.14 on BB-White, and am in special need for P8.03 P8.04 and P8.05, which are not exported as they are eMMC on the BB-Black. What is your recommendation for this situation?

[beagleboard] BeagleBone not recognising some SD card
I have a BeagleBone, it works fine with the SD card that came with it, its a Kingston, I bought an other SD card in order to try different OS installations, like Ubuntu, and keep Angstrom in the other SD card, the problem is that is not recognising the new SD card, my computer recognizes the SD card from the SD slot, but if I put it in the beaglebone it doesn't work, The BB doesn't boot and is not recognized by the computer, the brand of the new SD card is Adata, Why it works with some SD card and doesn't work with other?

[beagleboard] Ubuntu Kernel version with 'md' module ?
Hello all; I am currently using Ubuntu version: Linux ubuntu-armhf 3.8.13-bone20 #1 SMP Wed May 29 10:49:26 UTC 2013 armv7l armv7l armv7l GNU/Linux And the 'md' module which would allow me to setup a RAID array does not appear to be installed.

Re: [beagleboard] CE and ESD, BBB is failing 4kV contact discharge ESD testing
How is your esd protection designed at the usb connections, or are you hitting the usb connectors right on the bbb?

I'm guessing your esd protection may not be getting to a solid enough chassis ground close enough to the connector that is being hit.

Actually, from what I recall, the USB protection isn¹t in the right place. The correct layout is USB connector, ESD protection and then USB transceiver. However, in the BBB, the USB connector is connected to the USB transceiver and the ESD protection is on the other side of the USB connector. Granted, the distance is small and may even work correctly, but this layout doesn¹t follow good ESD layout principles.

Sorry, I can't help you with specifics of running Java, but it seems to me that you don't need the whole Eclipse environment---just the Java runtime.

You do not need HDMI audio to use the Android image. I have used it without an issue with the various LCD capes without audio, for example. Using the ethernet LAN connection and USB mouse are also supported. I will need more information before I am able to help you. Can you supply a complete FTDI output from bootloader boot through to about 60 seconds? The reason that I ask for this is because I need to see where the video resolution is being set in the TILCDC framebuffer driver. While there are a number of failed services in the logcat output that you provided in your other post, I need to see the results of the kernel booting output first before I can move on to helping you troubleshoot any user space issues. The logcat output shows that you are well into the boot process of user space. If anything is failing in kernel space, I need to know that first. Are you not seeing anything on your display? One of the most common problems is the EDID block not being sent from your monitor to the BBB. When this happens, the TILCDC kernel driver will default to a resolution of 1024x768 (which may not be supported by your monitor). This results in a blank screen. My first guess is that this is your problem (especially if you see it for both the old and new Android images). Are you stuck at the screen with the Android animation on it? You should not be, from what I can see of your logcat output.

Apparently, there are no problems with that, but they used features that are'nt available in 3.8. And they added the device tree support after this patch. So it will be difficult to make it work on 3.8.

RE: [beagleboard] Ubuntu Kernel version with 'md' module ?
Ok That's what I thought :( There is no way to just upgrade the kernel without completely rebuilding the Kernel? Would I not be better off just getting a more recent version say 3.8.13-bone22 ?

Your going to need to build and then install it. Do it on x86 then replace the boot files on your microSD card.
