没有隔离电源。共地没有处理好，是什么意思？是因为全桥逆变电路在直流输入电压侧造成的反向电流造成的么？

我也觉得是硬件问题，但是JTAG口连接好像是正常的，所有地也是连上的。因为PWM程序运行一小段时间才会DSP把JTAG口断掉。这个错误信号无法查明啊。不知道是哪里造成的。必须断电，拔掉PC与仿真器连接，然后重新连上，上电，才能恢复。只断电和上电，是不行的。

我也认为是硬件问题，但无法找到原因。JTAG口连接正常，虽有地也是连接的。每次出现问题，必须拔掉仿真器和PC连接，并且重新给硬件上电才能恢复。

试了一下，BOOT模式改为1111，flash模式，并没有什么变化。板子上2835控制的是两个半桥芯片CSD97396，做成一个全桥逆变，逆变电路，输出端连接电阻和电感电容，全部串联，在谐振频率下运行。当逆变电路输出端断开时，程序运行正常；一旦逆变电路输出端连上电阻电容电感，就会发生JTAG断开的现象。而且是在程序运行几秒或十几秒后，才发生的。

最后感觉应该是仿真器受到了干扰，但是干扰问题无法解决。我只能用JTAG口下载程序到DSP，但是不能调试和监控了，而且每次下载完，还需重启仿真器才行。用示波器对重要信号进行了监控。感谢SEVEN HAN，你说的应该是对的。
