我用的是XDS100V3烧录28034,用的淘宝上买的XDS100V3,150元;之前小批量,4,5百烧录没啥问题,这批烧了2,3百片就有4,5十片,烧录过程中进度条无显示,或者只显示一般就出问题;有2个仿真器,都是这样,换过2台电脑也这样;是什么问题导致;这种烧坏的片子再连接再烧录就不能连接上了,咋回事??有碰到过这种问题的么?
我只能根据您给出的错误提示来判断
1 The controller has detected a cable break that is near-to itself. The user must connect the cable/pod to the controller.
此错误表示JTAG调试器通过TDI引脚向器件发送数据,但未在TDO引脚上接收任何内容。一般是JTAG电路在JTAG调试探针附近或接近电路板时断开。建议您检查一下线路问题
2 Device is not responding to the request. Device may be locked, or the emulator connection may be unreliable. Unlock the device if possible (e.g. use wait in reset mode, and power-cycle the board). If error persists, confirm configuration and/or try more reliable JTAG settings (e.g. lower TCLK).
此错误是由调试探针无法与设备通信引起的。一般是芯片被锁了或者是硬件问题,您可以看一下
3 The JTAG IR and DR scan-paths cannot circulate bits, they may be broken. An attempt to scan the JTAG scan-path has failed. The target's JTAG scan-path appears to be broken with a stuck-at-ones or stuck-at-zero fault. (Emulation package 7.0.100.0)
