编译软件 CCS3.3  芯片DM642 ，自己做的板子，仿真器采用的是XDS510，在connect 过程中 先Reseting 然后就直接disconnect 出现以下错误，可能哪地方出现问题？
Trouble Writing Memory Block at 0x1800020 on Page 0 of Length 0x4: Error 0x00000022/-1154 Error during: Memory, Execution,  The memory at 0x00000000 continually indicated it was 'not ready' The emulator was unable to regain control of the processor. The processor must be reset.   Sequence ID: 66 Error Code: -1154 Error Class: 0x00000022

在GEL文件中 将GEL_MapAdd( 0x01800000, 0, 0x00000058, 1, 1 );  // EMIFA CTL REGS 注释掉后 ，可以正常连接目标班，编译软件处于HALTED 。提示如下错误：

GEL: Error while executing OnTargetConnect(): memory map prevented write to target memory at 0x01800000.

打开工程后 编译下载后 提示如下错误,但是不影响简单程序的运行：
GEL: Error while executing OnTargetConnect(): memory map prevented write to target memory at 0x01800000.
GEL: Error calling OnPreFileLoaded(): memory map prevented write to target memory at 0x01800000
