Mounting failed, not entering SDK so~,i read the script 'mer-sdk-chroot' and find the output "Mounting failed, not entering SDK" is from here: ################################################################ # utility ensure_mounted() { echo $sdkroot if ! grep " $sdkroot " /proc/mounts > /dev/null; then cat <<EOF This SDK ( ${sdkroot} ) does not appear to be mounted yet - attempting mount: EOF if $0 mount; then return else echo "Mounting failed, not entering SDK" exit 1; fi fi } now,if i run 'sudo mer-sdk-chroot mount',it will be done~
