默认情况下，J7 SOC 的 MCU 和 DSP 内核不会为串行端口输出设置单独的 UART。对于 TDA4X，默认情况下，除 A72 内核之外的每个内核的日志都将写入一个共享存储器，然后 A72 应用程序会读取这些日志并将其打印到 MAIN_UARTX 串行端口。但是，为了方便调试，通常有必要同时打印多个内核的日志，或者在内核 A 不能正常工作时继续打印日志。在这种情况下，需要为 MCU/DSP 内核配置一个单独的串行端口。下面以 TDA4VM 为例为 C7 设置单独的串行端口。

上面介绍了 SDK 级别的所有更改。只需要执行下一步操作即可重新编译 C7 固件并将其刷写到 SD 卡或 EMMC 中。
