Thanks. Ubuntu 12.04 versions do not support armel. We tried downloading and writing pre-built Ubuntu 11.04 Core armel supported binaries, but the board refuses to boot from the SD card. We have tried alternate versions of armel builds of Ubuntu and Debian but without success.
While we revisit what could have gone wrong, would you be having an alternate Linux ARM build of the ThingWorx agent that would support Ubuntu built for hardware FPU support ? Any other inputs would also help.
