錯誤現象：
在使用xds100v3仿真器調試tms320c6747處理器時，出現如下一堆錯誤。
C674X_0: Power Failure on Target CPU
Error connecting to the target:
(Error -1265 @ 0x0)
Device ID is not recognized or is not supported by driver. Confirm device and debug probe configuration is correct, or update device driver.
(Emulation package 7.0.188.0)
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)

原因：
查了很多硬件原因和軟件原因，都無解。
解決辦法：
更換仿真器爲幾千塊的xds560v2，問題解決。
