AM6421: SysCfg使用问题

您好，

我是用SysCfg配置两个UART的时候，如下图所示：

当两个UART都配置成HLD的时候编译没问题，但两个UART都配置成LLD的时候，编译出错，请问是什么问题？

谢谢！

?? ?：

MCU+SDK是10_00_00_20

syscfg是1.20.0

编译器是TI Clang v3.2.2.LTS

Lydia：

您好，

我可以看到您正在尝试在UART_Write调用期间使用gUartHandle变量，但此变量未定义。

请尝试使用gUartHandleLld一次。

,

您好，

按照您的建议使用gUartHandleLld之后，又报出新的故障，如下图所以：

相应的console显示如下：

ti_drivers_open_close.c中相应的程序如下：

请问是什么原因？

,

Lydia：

您好，

我可以看到上面的错误是因为gUartDmaChCfg变量的重新定义而出现的。 您能否确保在应用程序代码中不再重新定义相同的符号？

,

?? ?：

您好，

如最后一张图所示，是syscfg自动生成的文件里重复定义了gUartDmaChCfg，请问是SDK的问题吗？

,

Lydia：

您好，

我已经在最后尝试构建示例、我能够毫无错误地构建它。

我使用 AM64x MCU_SDK v10.01和 SysConfig v1.21.2、CCS v12.8.1。

如果问题仍然存在、请尝试重新导入工程一次。
