TI中文支持网用的CCS6.1.3，仿真器用的是XDS100V3，第一次点击connect时，提示如下：
IcePick_C_0: Error connecting to the target: (Error -151 @ 0x0) One of the FTDI driver functions used during the connect returned bad status or an error. The cause may be one or more of: no XDS100 is plugged in, invalid XDS100 serial number, blank XDS100 EEPROM, missing FTDI drivers, faulty USB cable. Use the xds100serial command-line utility in the 'common/uscif' folder to verify the XDS100 can be located. (Emulation package 6.0.222.0)
拔掉和PCB板连接的插头，再插上，连接正确，可以烧写程序，然后运行，过一会就自动断开，提示如下：
C28xx_CPU1: GEL Output:Memory Map Initialization Complete
C28xx_CPU1: Error: (Error -154 @ 0x0) One of the FTDI driver functions used to write data returned bad status or an error. (Emulation package 6.0.222.0)C28xx_CPU1: Unable to determine target status after 20 attempts
C28xx_CPU1: Failed to remove the debug state from the target before disconnecting. There may still be breakpoint op-codes embedded in program memory. It is recommended that you reset the emulator before you connect and reload your program before you continue debugging
请问下，这是什么问题呢？需要怎么改善呢？谢谢了！

按照提示说的，返回的状态不对，单步调试，看看问题出在哪里了

我有看到很多帖子，解决办法都是 重新装驱动，我也试过了，可以支持一会，过一会就断开了。
还有我的DSP电源 TPS70345发热非常严重，大概80°左右，这个会不会有关系。

第一个问题解决办法：
1、XDS100仿真器没有连接到PC，重新拔下再插入仿真器；
2、XDS100仿真器的驱动没有安装或是安装不正确，删除驱动重新安装（CCS是自带XDS驱动）；
3、工程里的仿真器选择的版本不正确；
第二个问题需要连上之后单步调试，看看问题出在哪里

我一共画过两次 28377D的板子， 第一次的板子，连接，下载程序都正常；换成第二次的板子，就会出现 那个FTDI的问题，而且接上板子之后，电脑的设备管理器
界面不断的在刷新，请问下，这可能是硬件上的什么原因引起的呢？

检查下这块板子的供电是否正常，jtag接触是否良好。
