William, thanks for taking the time to answer. I'm using TightVNC to remote to the BBB, so native development is a go. How would flash get ruined? So do you mean having a secondary rootfs? Is it possible to have the rootfs on an sd card and everything else running from eemc as-is? So back to

I think William is right about developing natively on the beaglebone. The GUI design could be done from other desktop and copied to BBB, or done natively. So are the cpp files (if you are using C++, I don't know how to do other languages like Python or bonescript). But all the program files (to me

Henry, many thanks for the info and congrats on the new addition to the family! Some of the pages of the book are available online and the example section at the end is exactly the example I was looking for. I went ahead and ordered it off Amazon Prime. Looks like installing QT4 and QT

Frank, thanks. The 'good sleep' really sounds ancient to me. But I love my wife and daughter, so everything that is in trade is worthy. Anyway, I'm glad that you feel more on track now. Let me know if you have any further questions (especially questions in detail) so that we can discuss and grow

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

Dear Eric, It turned out that If I restart the BBB, the DHCP will work normally. Don't know the reason, but at least I know how to solve this problem. Now I can SSH to the BBB as root from terminal. What you described is exactly what I expected: whenever I turn on the BBB, after the system

If you Google “Beaglebone latest images” you will see that the OS of choice (and best supported) is Debian. I suggest that you flash that image to your uSD card. From: beagleboard@googlegroups.com [mailto:beagleboard@googlegroups.com] On Behalf Of Henry Yongfan Men Sent: Saturday, June 13,

Dear all, I'm a complete newbie in this community. As a postdoc, I'm responsible of building a off-computer control system. I decided to use BeagleBone as the central controller. But since I have other academic jobs, I wish I could finish the project quick and dirty. So maybe I need some

did you want to use soft buttons (buttons generated on the touchscreen as needed in software) or hard buttons (buttons on the display that consist of an actual hardware switch that causes a detectable contact closure) for this? For the soft buttons I'd look at Qt. For the hard buttons, look at

As a quick hack, the hard button(s) may be easier with less code, but you are right, using the soft button approach with software based menus is much more flexible. With the touchscreen attached, the beagle starts running it's display on the touchscreen and enables the touch interface as if it
