Hi wdzwdx, 

 On your custom board, is the flash base address still 0020_0000?  --Scott

I&#39;m sorry!! I can&#39;t make out what you exactly mean! 

 When I create my custom board, it set my flash base address to 0x0200000 automatically, and when I use my custom board, I set it to be 0x0000000. Is there any problem about the base address setting??  thanks!
