我使用的VC5509，硬件仿真器为XDS510，在做外扩SDRAM的时候，写不进去数据。请教各位帮忙解决，谢谢
报错如下：
Trouble Reading Memory Block at 0x6005 on Page 1 of Length 0x1:
Error 0x80000002/-1143
Fatal Error during: Memory,
The memory at 0x0000C008 continually indicated it was 'not ready'
All memory operations currently in progress were aborted in order
to regain control of the processor.
This is considered a catastrophic event, but the debugger should
still be able to access memory and CPU registers.
System state has been altered.  It is strongly advised
that the processor should be reset before resuming execution,
