Re: [beagleboard] OSX + Baeglebone = Nightmare

I am running 10.10 and have trawled the internet reading pages upon pages of cryptic mumbo jumbo, I have uninstalled rivers, updated drivers, replaced drivers, edited pLists, reset Pram, reset SMC, I have done EVERYTHING. I am sick of it at this stage. I have a €100 Windows 7 netbook that connects with no problem to the Beaglebone. For the past 9 months of=r so I have used an Arduino Mega with no connection issues, so why oh why is it so difficult to get this POS board to work? Laziness perhaps? Basically Beaglebone need to get their finger out and fix the driver issues with OS X. OR STOP SELLING THIS BOARD to OS X users. It just doesn't work. My weekend has been a complete waste. Windows 7 works with the Beaglebone, OSX 10.9 works, OSX 10.8 works, Linux x86 works. If OSX 10.10 does not work the blame is on the Beaglebone side? As you have only trawled the internet for a weekend reading mumbo jumbo, for a weekend, it seems to me that you need to spend lots of time reading more stuff. Count on at least a month. until the mumbo jumbo starts making sense. Yes, the Beaglebone IS NOT an Arduino! The Arduino Mega has only a serial over USB connection, and is a 16 Mhz, 8 bit processor without any Operating system. The Beaglebone is a 32 bit full grown computer, with network, HDMI, memory management and protection, LInux, and it is a very, very different machine. Yes, the prices are very similar, but the value is very different. Some people only look at price, other can look at the value and the support and the knowledge that the guys behind the Beaglebone offer. Hope someday you can do the latter. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

Re: [beagleboard] Coding with C/C++ directly on Beaglebone, via IDE?

Renounce to auto correction, color syntax, auto completion, and a ton more of functionalities, when you are coding millions of lines, is not different from running win 3.1 on a modern computer :) As much as I love terminal, there are things that are not feasible without a good text editor with plenty of functions; without even mentioning the pros of a real IDE, when you need to debug and such. Well, last time I checked vim has (even in text mode): Color syntax (and syntax checking when doing save) : https://github.com/scrooloose/syntastic Auto Completion and more: http://www.vim.org/scripts/script.php?script_id=213 When I compile it can place me on the file and on the line where the error is...

Re: [beagleboard] Angstrom Abandoned for BBB? Rumor + a Rant
On 30/12/2013, at 02:03, Mike Bremford m...@bfo.com wrote: Where is this documented? And why should I care? The above two paragraphs are unintelligible to anyone that hasn't been involved in embedded Linux for some time. It seems you are barking at the wrong tree. Unix is a tool. A powerful tool. As all powerful tools, power should come after some knowledge and practice. Think of a razor sharp kitchen knife, a chainsaw, an arc welding machine, a forklift, a pickup truck. All those are examples of very useful tools, but they only can be used in a productive way, after some practice time, and after having acquired some knowledge about how they work, and how to use them correctly. The standard phrase is that Unix is very user friendly, but picky about the friends... You can approach Unix at several levels: 1) User level - command line use of the Unix utilities, and understanding of shell scripts 2) Admin level - know how to manage users, programs, networking 3) Programmer - know the POSIX programming model and all the UNIX programming tools (config, make, gcc, etc...) 4) Kernel developer - all of the previous ones + how to compile a kernel If you want to work with BeagleBone, you must at least understand that many people are doing all those levels on the cutting edge of technology, and that knowledge takes time, because you need to make things, to understand how they work. The saddest thing, is that people want things done (or instant gratification) without being involved. Open Source does not work that way, and most important, life does not work that way. In order to do things, in order to get what you want, you need to involve yourself.

Re: [beagleboard] Hardware info on USB A port

Now assuming that all LS/FS/HS USB specifications are the same, how can this happen? Any suggestion on what I can be missing that is not the same ? Please try an oscilloscope. That's a good suggestion. Have to find one. hvn Well, between a normal PC and a BeagleBoard, the only things that change are: the compiler, the processor's architecture, the processor's clock speed, the memory interface, the caches, the peripheral's connection to the processor and the interrupt architecture.

Re: [beagleboard] USB errors (and hotplug work-around)
You issue may be there (or not). To really really know, you can use some wide bandwidth digital oscilloscopes to see how the USB signals are behaving. Or try to use a good shielded USB cable. Guess what is the cheapest option, try it, and after that please tell us what did you find. Best regards Paulo Ferreira On 28/10/2013, at 14:22, Bai Shi baishi...@gmail.com wrote: Erm.. very good question. It indeed is the same external power supply connected to the Beagle Board. Or I would say all the power come from the same ATX power supply though it might (tiny little chance) be in different rails. Frankly speaking the line was rather short (less than 5cm) so I didn't bother to do shielding at all. The D+ and D- is using Cat5 ethernet cable. Does it make any significance?

Re: [beagleboard] Using beaglebone black as a programmer for other MCU's
On 14/10/2013, at 14:10, Gal Rubinstein gal...@gmail.com wrote: hello all, I brought a the black a month ago and i really like it, doing a lot of nice things withe the GPIOs my question is: is there a way to emulate the functionality of the JTAG (or whatever else) to program the other MCU using the baglebone's expansion pins? like ATiny which uses the Arduino board as the programming device to program to other MCU's (of the same family) . BTW: I know I will need to compile the code to fit the other MCU using the manufacture's supplied headers... had some experience programming the STM32… Today, JTAG is used for many things. 1) Checking if the PCBs are ok ( the original intent ). 2) Programming the flash ROMs, or EEPROMs or FPGAs. 3) Debugging the software, with GDB single stepping (or breakpointing) the target microprocessor. So besides wiggling or shaking in the right way some pins of BeagleBone, you need lots of software behind for all that to work. So the fast way to have the BB program some microprocessor is to buy a cheap USB-JTAG adapter supported by these two software packages: http://openocd.sourceforge.net http://urjtag.org Best regards Paulo Ferreira -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

Re: [beagleboard] Remote debugging thru SSH
The subject line is about debugging, but you talk about updates on the main message. You are assuming that: 1) Every BB that needs to be updated is connected to the internet. 2) If they are connected to the Internet, the SSH port is wide open… 3) They are not turned off in the middle of an update… ;-) ;-) Why not auto update your app? When booting the BB the init script compares the release number of you app (somewhere in a file or in a filename) with the current release number. The current release number is available from an update web server (with the software). If the release number on the web site is greater than the installed, the script downloads the app, checks the integrity of the archive, and if the archive is ok, upgrades the software. This: 1) Works with only the http port open. Does not need any other ports opened. 2) Works also on a network no connected to the Intranet, as long as you place on that network a suitable web server. Warning: I don't think this update method is the subject of any valid patent, but... ;-) ;-) ;-) Best regards Paulo Ferreira -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.
