When I insert addresses like 0x0a0, 0x0a4 etc in.

I have used git to clone the pertinent files directly on the BBB; I have removed all comments from the first fragment; I have tried keyboarding the code beaglebonne hand into a duplicate file to eliminate any invisible character. Please ignore my above question. Even your TestApplication worked right out of the box.


I am using the ethernet port so instead of the … address I find my BBB at The latest flasher images are available at: I would love to see datalogger example video. I still get high if it was initially configured with pull-up, or low if initially configured with pull-down.

I tried copying your code by cutting and pasting but can do that in the putty window I guess so I did manually type it in. You can actually find out the source location of a package in advance of installation by typing: Are the steps needed here different if running Windows 8 or 8.

Thank you in advance! Derek, I really like your book. Can you ping http: Please use the comments section at the bottom of the chapter web pages if you notice any other compatibility differences that should be noted.

Manage Linux packages back set the system time. Hi Derek; Sfm for writing this book. It seems login success, at least, username and password is correct. Which I did do successfully. There is also a console image that frees up more space if you are using the BBB in headless form. I earlier tried writing from scratch, your dts file from this video resulting in the same error message.

Y Thanks for your videos and blog posts on the Beaglebone and thanks for your help. The advantage of the eMMC version is that once it is written to the eMMC which takes about 5—25 minutes the BBB will boot in about 10 seconds from then on, and the micro-SD card slot will remain available for additional removable storage.

And I want to use that pins as normal pins. I am trying to do some basic things with the BBB. Especially on Device Tree in Linux. I have been documenting my project on a Blogger page, and I have just added links to your baeglebone.
