fedex4u 0 Posted July 3, 2014 Share Posted July 3, 2014 Hey All - pretty new here to Energia, but have run across an issue that I can't seem to troubleshoot. I'm running the following: OSX 10.9.4 with Energia 0101E0012 Stellaris Launchpad LM4F120H5QR The first upload always works fine, but following uploads to the device will randomly restart OSX. No warning, just a momentary mouse freeze, black screen and system restart when the progress bar gets to 50%. Serial Port is dev/tty.usbmodem0E102F71 (only option available). Bluetooth is turned off. This has occurred with all different types of 'code' as well - from built in examples to things I wrote myself. Thanks in advance for any advice any of you may have!

eck 4 Posted July 4, 2014 Share Posted July 4, 2014 I've seen something similar before, just with an Arduino board. I think the ACM driver framework in Mac OS X is quite sensitive. Which drivers are you using for the USB port? Quote Link to post Share on other sites
Rei Vilo 695 Posted July 5, 2014 Share Posted July 5, 2014 What is the revision of the USB port? Connecting a LaunchPad to a USB 3 port may produce strange results. Another thing to explore: any power hungry circuit or any kind of shorts on the circuit? This could drain more than 500 mA and force a hard reset if the Mac. Quote Link to post Share on other sites
madias 0 Posted July 8, 2014 Share Posted July 8, 2014 This has nothing to do with the USB Port. See https://github.com/energia/Energia/issues/390 It Quote Link to post Share on other sites
