Part Number:TMS320F28335
如题,开始未去掉看门狗电路仿真器连不上DSP,意思到问题并去掉看门狗电路后仿真器连DSP报错:C28xx: Error connecting to the target: (Error -233 @ 0x0) The JTAG IR and DR scan-paths cannot circulate bits, they may be broken. An attempt to scan the JTAG scan-path has failed. The target's JTAG scan-path appears to be broken with a stuck-at-ones or stuck-at-zero fault. (Emulation package 7.0.188.0) 。该问题如何解决?谢谢
Green Deng:
你好,外部看门狗是指什么?就是普通看门狗电路吗?还是外接的电源管理芯片?
现在芯片的复位引脚是什么状态?悬空的吗?
复位引脚有没有方波信号?

看门狗是这个芯片APX823-31W5G,dsp的复位引脚接到该看门狗芯片的reset引脚了

复位引脚有没有复位信号?也就是方波信号?
