F28069 锁死

 

请教专家!!!!我用的是F28069的芯片,connect芯片时候出现下面这种问题。仿真器器不能连接芯片,可能被锁。

我知道芯片被锁后不能下载程序。我想了解一般正常被锁的芯片,还能不能连接仿真器,能不能reset,还有除了加密,其它还有什么操作芯片可能被锁。

Error connecting to the target:
(Error -1015 @ 0x0)
Device is not responding to the request.  Device may be locked, or the emulator connection may be unreliable. Unlock the device if possible, and power-cycle the board. If error persists, confirm configuration and/or try more reliable JTAG settings (e.g. lower TCLK).
(Emulation package 5.0.872.0)

  • 请做下面操作看看是否能够连接芯片:

    1. 断开仿真器连接
    2. 跳线bootmode为wait模式
    3. 复位芯片
    4. 重新连接仿真器
