28335 调试问题

  • TI员工您好,我也遇到了类似问题,flash现在无法下程序,现在只有在RAM下并且BOOT模式选择为skip ADC calibration仿真器才能与DSP链接,程序可以load进去,但是无法运行,显示如下错误C28xx: Trouble Reading PC Register: (Error -1041 @ 0x0) The emulator reported an error. Confirm emulator configuration and connections, reset the emulator, and retry the operation. (Emulation package 5.0.747.0)
    C28xx: Can't Run Target CPU: (Error -1140 @ 0x9765) Lost debug connection to device. Reset the device, and retry the operation. If error persists, confirm configuration, power-cycle the board, and/or try more reliable JTAG settings (e.g. lower TCLK). (Emulation package 5.0.747.0)

    请问我该如何解决

  • 芯片可能被锁了,前年我也遇到过一次类似的,不过不是这个款芯片,是TI的另外一款,忘了是哪个了。当时折腾了很久才救活,一般不小心锁了,基本上是没救了。

    这个贴里,TI员工给的方案是换芯片。回头我找找哪个救活的方法,再来补充。

  • 跟下面这个测评里提到的问题很像,楼主试试看。
