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！
已经收到了您的案例，调查需要些时间，感谢您的耐心等待。
请说明您使用的是哪个版本的MCU+SDK。
请分享完整的错误日志，找出问题的根本原因。
MCU+SDK是10_00_00_20
syscfg是1.20.0
编译器是TI Clang v3.2.2.LTS
感谢您提供上述详细信息。 此外，请发送构建过程中出现的完整错误日志。
完整错误日志如下：

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。
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？
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？
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？
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。
