Can not boot from the AT91SAM7x256

I use the ULINK to debug the troubles why the code can not work in AT91SAM7x256. The following is my memory mapping. In the target environments, the ROM address and SRAM address are set to 0x0010-0000 and 0x0020-0000, respectively. Now I use blinky samples from Keil to test my board; but I don't know why it can not boot code. I found the code was loaded to the memory address 0x0000-0000, not the 0x0010-0000.
The tool ULINK is running from the 0x0010-0000 and locate the code 0xFF, not 0x18. This is why it did not work. Who can I tell why the code was loaded to the 0x0000-0000 ? Or how to solve the problem ?
The ERASE pin now is pulled high for GPNVM setting to boot code from the internal flash.
