July 25 Working inside Haiku LMS

Currently working inside the course in Haiku LMS to verify and document the install for devices the course will support.  Want installs to be smooth and hopefully fast. Here is a screen shot of Devices overview page.

CBCv2 is expected to be the first device fully supported and documented in the course.

July 5 LMS Flashing and drivers

Normally when NXT acts odd, reflash firmware and all is fine. But what can be done with the device not recognized and comes up as Unknown Device / faulty device? This post document the symptons and a simple solution that worked.

I use my NXT with various software and firmware for teaching children NXT Mindstorms (waterbotics) and Lejos, Enchanting, a Scratch like puzzle language, as well as ecos with Forte for this project to teach industrial automation.

Last week my NXT got confused and would not let programs to be downloaded. Finally decided to reflash the firmware.

NXT Mindstorms software normally recognizes an NXT even if other firmware is loaded or in reset mode. It didn't.

Device driver listed as Unknown device, even on my laptop with Atmel driver and SAM-BA.

Tested my set-up with another NXT and the driver showed up, both for Lego and in reset mode.

Somehow connecting a working NXT, fixed the general driver problem. Afterwards the faulty NXT was recognized as a known device, so flashing was easy. In this case the Mindstorms firmware renamed from .rfx to .bin, since was on my development laptop, but its summer workshop time. 

Back to LMS forte next week.
