Re: Bricked Sheevaplug



Either way would be fine. An OCD will need to be installed on my Windows XP machine to.

I have the FTDI USB driver for Windows installed and used it to configure the PLUG when the Sheeva Uboot was installed. I moved to the open source, DENX, uboot using Martin Michmayer's article located at http://www.cyrius.com/debian/kirkwood/sheevaplug/uboot-upgrade.html at the time there was a problem with the USB hard drive booting Debian OS. After upgrading to DENX uboot I have an issue reaching the PLUG through the console port from the Windows box. While watching the Windows device manager screen the virtual com port comes and goes in the port display.

Hope what I have described above all makes sense. :-)
