调试板为 rv-debugger-plus，目标机器是sipeed nano，编译出来发现jtag能用，但是uart无通信。起初怀疑硬件的问题，但对比烧录sdk example下的usb2uart用例，uart通信正常，所以认定是固件bug，请排查一下。

把这一行注释掉，重新编译然后烧固件就行了，但是我还没测试jtag好不好使

RV-Debugger-BL702/firmware/app/usb2uartjtag/uart_interface.c

Line 74 in cdc36a4

device_control(uart1, DEVICE_CTRL_SUSPEND, NULL);

这一行在 usb2dualuart下面是被注释掉了的

RV-Debugger-BL702/firmware/app/usb2dualuart/uart_interface.c

Line 56 in cdc36a4

// device_control(uart[index], DEVICE_CTRL_SUSPEND, NULL);

小编也很好奇为什么
