Hi Sridhar, You could try re-flashing the default firmware using your Overo. # cd # wget http://cumulus.gumstix.org/sources/robovero/x-tools.tar.gz # tar -xzf x-tools.tar.gz # opkg install libftdi # wget http://cumulus.gumstix.org/sources/robovero/openocd_0.4-r0.6_armv7a.ipk # opkg install openocd_0.4-r0.6_armv7a.ipk # wget http://cumulus.gumstix.org/sources/lpc1769.cfg # cp lpc1769.cfg /usr/share/openocd/scripts/target Now you should have a working build environment. You can download a pre-built binary (good) http://cumulus.gumstix.org/sources/robovero/firmware, a tarball of the source (better) https://github.com/robovero/firmware/tarball/master, or clone the repository (best) git://github.com/robovero/firmware.git. The major advantage to the latter two methods is that the source includes a script that will automatically run openocd and gdb for you. Let me know if you run into any problems. - Neil On Fri, Sep 2, 2011 at 8:18 AM, Sridhar Anandakrishnan <sa...@es...>wrote: > Hi - I purchased an Overo board and the Robovero expansion board. > > According to the documentation, the firmware on the robovero board is > already in place. > > As I understand the information at this webpage, I should be able to > access the robovero LPC microcontroller right away. > http://wiki.gumstix.org/index.php?title=RoboVero#Pitfalls > > However, when I apply power, no LEDs light. > When I attach the USB cable (mini USB to J8), a green LED labeled R9 (just > to the left of the connector as viewed from off board) comes on.
