Open On-Chip Debugger for Dreamplug
« on: 18 November 2012, 09:11:20 pm »

Hi, when trying to follow the instructions at:

https://www.newit.co.uk/forum/index.php?topic=2835.0

I see the following results when performing the steps on Ubuntu's Precise Pangolin (http://packages.ubuntu.com/precise/openocd).

Any recommendations?

Thanks,
Thomas
