Other Parts Discussed in Thread: TMS320F28027, LAUNCHXL-F28027F
主题中讨论的其他器件:TMS320F28027、 LAUNCHXL-F28027F
我无法使用 XDS 110调试探针将代码"刷写"到 PCB 上的微控制器(TMS320F28027)。 PCB 上的微控制器已成功编程为 RAM 配置。 我已进行了必要的更改(更改.cmd 文件)。
在使用 XDS 100V2调试探针的 Launchpad (Launchxl-f28027F)上使用时、相同的代码在"闪存"模式下工作。
我已包含必要的.cmd 文件。

我包括以下行:
memcpy (&RamfuncsRunStart、&RamfuncsLoadStart、(size_t)&RamfuncsLoadSize);
InitFlash();
编译设置设置设置为:

以下是 PCB 上电路板的调试连接原理图:

代码是 对'Example_2802xEPwmDeadBand'的简单修改。
