仿真器连接不上28335

C28xx: Error connecting to the target: (Error -1155 @ 0x0) Device may be operating in low-power mode. 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 5.1.450.0) 

Seven Han：

是否有测板子电压？

以前有没有连接上过   重点判断是仿真器出了问题  还是目标板出问题了  

检测驱动      板卡复位   时钟   

看看clkout是否有输出
