Original question:

28377S的晶振问题

TMS320F28379D: launchpad晶振存在1V左右直流偏置，而我采用datasheet的外部晶振接法不存在直流偏置

Part Number: TMS320F28379D
Other Parts Discussed in Thread: C2000WARE, UNIFLASH

我的振荡电路参考了Launch_Pad，与芯片手册推荐相同但波形不同，无法烧录。

    您好，

          晶振不起振，请检查板子上芯片所有电源和地的连接，复位脚的连接。

    你好，向您请教下，28379DBOOT引脚GPIO72/84我没有引出并拉高，我想他是默认拉高的（也就是flash模式），这对28379D启动会有影响吗，谢谢,这会是晶振此现象的原因吗，谢谢

    您好，

          BOOT引脚要设置，以确保正确的启动流程。

    你好，所有电源检查均正常，BOOt引脚GPIO84/72均拉高（getmode），外接仿真器X100v1，无法烧录显示CPU为连接，唯一存在的问题是晶振的振荡相较于Lauch_pad没有直流偏置，请问可以解答一下吗

    您好，

            现在芯片不是还没编程成功吗？那没法使用getmode。

           TRST脚怎么接的？

    你好，谢谢你的回答，我的接线如下，下载程序时开关均置于ON，FLASH MCU会失败，晶振相较于Launch_pad不存在直流偏置

    您好，

          用JTAG时，TRST复位信号正常吗？

         从您的电路看不出来有什么问题，如果确认芯片的供电复位都正常，芯片就是不起振，建议用评估板的晶振测试一下，否则就是layout问题，

         在c2000ware 的安装目录内有评估板的设计文件及BOM。。

    你好，谢谢你的解答，使用JTAG时TRST引脚约为2V，我将有片外电源引脚逐一测试均正常，但是使用PLECS仿真（配置如下）时出现以下错误，无法连接cpu

    您好，     

         PLECS不是TI的软件，这个软件的调试问题我们无法支持更多。

        请问TI的 XDS系列调试器+CCS/UNIFLASH是可以编程成功吗？

        如果可以，说明就是PLECS与匹配的调试器的驱动问题。
