2. Check if the fuse (F5) blew.
3. Check if the U2、U3 and U4（Flash & SDRAM）chips are placed
inversely, soldered poorly or short.
4. Check if the voltages VCC_SDRAM＝1.8V and VCC_NFIO
=1.8V are fed the SDRAM and NAND flash. If the VCC_SDRAM
and VCC_NFIO are abnormal, try to change a new DA9030
Power IC.
