HELLO! BOOT0 is starting! boot0 version : 1.5.1 dram size =1024 Succeed in opening nand flash. Succeed in reading Boot1 file head. The size of Boot1 is 0x0003c000. The file stored in 0X00000000 of block 2 is perfect. Check is correct. Ready to disable icache. Succeed in loading Boot1. Jump to Boot1.
