I am facing similar issues with a new Mele 2000 (v1.7 ?). Booting from SD card results in a hang condition. The serial console didnt show anything useful.. U-Boot SPL 2011.09 (Aug 21 2012 - 14:44:02) MMC: SUNXI SD/MMC (It appears stuck after this..) Tried with 2 different micro SD cards (Transcend/Sandisk make, Class 4) with no success.by yuvi - Allwinner A10
