在CCS8.0中没有TMS320VC5509型号选择问题

Other Parts Discussed in Thread: TMS320VC5509A

问题如图,我实际工程的芯片用的是TMS320VC5509A的型号,但是CCS8.0里面只有TMS320C5509A,少了一个V”,我不知道这有什么区别,因为我选这个一直连接不了,早先的时候可以连接,但是run总失败

  • 选c5509A可以的,都是c55x的内核。

    之前可以连接,现在不能连接是由改动过硬件吗?报错信息是什么?
  • Error connecting to the target:
    (Error -516 @ 0x0)
    The user selected specific frequency failed the scan-path reliability test.
    The utility or debugger requested the JTAG controller and cable,
    that generate the JTAG clock, to provide a user selected fixed
    frequency. The built-in scan-path reliability test has failed.
    This indicates that the JTAG controller and its cable cannot
    reliably communicate with the target system at that frequency.
    (Emulation package 7.0.188.0)

    以上是报错的信息;

    硬件没有改过,用CCS3.3和510仿真器是可以连接成功的,但是仿真会跑飞,可能是我程序有点问题。但是现在我用CCS8.0和XDS100V3就连接不上,出现这种问题
  • 可能是硬件不稳定。请检查一下电源和复位信号,或者测量一下CLKOUT管脚上的信号。
