hi，
I read tutorials in :http://releases.linaro.org/12.05/android/leb-panda/ I Build a Custom Image and download 3 files: boot.tar.bz2, system.tar.bz2,userdata.tar.bz2。 the step is:
# Create media $ sudo linaro-android-media-create --mmc /dev/sdX --dev panda --system system.tar.bz2 --boot boot.tar.bz2 --userdata userdata.tar.bz2
# Get binaries $ wget http://releases.linaro.org/12.05/android/images/panda-ics-gcc47-tilt-trackin... $ chmod a+x install-binaries.sh $ ./install-binaries.sh /dev/sdX2 "device node of system partition"
then , i boot pandaboard ES,but failed. here is the information from minicom.
