6678开发板可以连接仿真器，但是当下载代码时会出现以下错误，
Trouble Writing Memory Block at 0x8dc428 on Page 0 of Length 0x14b: (Error -1190 @ 0x8DC240) Unable to access device memory. Verify that the memory address is in valid memory. If error persists, confirm configuration, power-cycle board, and/or try more reliable JTAG settings (e.g. lower TCLK).
麻烦TI的工程师看看这是什么问题，就是突然就下不进去的
