自己设计的板子,芯片是TMS320F2812,一共100块板子,大概有50块连不上上CCS6.1,仿真器用XDS100V3,提示如下错误:
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 6.0.222.0)
测试电源3.3V和1.8V都没有问题,复位信号,晶振也都ok。
将复位信号按下时尝试连接,错误与上面一样。
