First question is can L2.6.35_11.03_ER_source be used on the iMX53 QS Board? My 53 QS Board comes with L2.6.35_11.01, how do I upgrade it to L2.6.35_11.03? Can someone provide a detail procedure for doing that? Do I just run install inside L2.6.35_11.03_ER_source? Do I need to remove the old linux-18.104.22.168 folder (and the u-boot folder) in the rpm/BUILD folder?
