我用的是 研旭的28335一体板，做整流的控制，simulink仿真是没有问题的，但是一到实验，只要用flash装载程序，一加电压，pwm输出波形就发生严重振荡，有大量高次谐波，连输入的交流电压也发生了畸变，产生了很多高次谐波，用仿真器的话，一加电压就会出现出错
”IcePick_C_0: Error: (Error -154 @ 0x0) One of the FTDI driver functions used to write data returned bad status or an error. (Emulation package 8.4.0.00006)
C28xx_CPU1: JTAG Communication Error: (Error -154 @ 0x0) One of the FTDI driver functions used to write data returned bad status or an error. (Emulation package 8.4.0.00006)
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“
我初步怀疑是不是功率电路对控制板产生的干扰，但是又无法确定，有没有遇到这类问题的朋友帮助解答一下呢
您可以看一下
如果JTAG扫描管理器软件向XDS100中的FTDI芯片发送命令，并且FTDI驱动程序返回错误代码或错误数据量（通常是数据中的嵌入式错误代码）时，都会发生此错误。这可能是由于USB连接不可靠（进出FTDI芯片的数据损坏），硬件问题（XDS100中的FTDI芯片无法正确响应）或扫描管理器软件中的软件错误引起的。
并给出了相关建议：
If the error happens continuously, this is very similar in nature as the Host connection error and similar workarounds mentioned there are applicable.
If the error happens suddenly, then noise or ground problems may be the root cause and the aspects mentioned in the Hardware checklist are applicable.
