程序正常跑起来的，没有进入DefaultISR了，串口是有发送数据的，用逻辑分析仪是能看到的，但是就是接收不到，麻烦帮我看看我的YCT和代码，哪个地方配置错了，谢谢Linflexd_Uart_Interrupt_Demo.yct

时钟配置补充

Diga

NULL 是空指针，不会进这里的。
是进的 HardFault？Hardfault 状态是什么

Follow

Diga 在 YTM32B1MD1 Uart中断接收DEMO修改的程序会进入DefaultISR ，用官方DEMO配置也是一样的中说：

HardFault

是进入了DefaultISR，麻烦你帮我看看我的串口的驱动配置哪里有问题，谢谢

run

在LINFlexD_UART_DRV_InstallRxCallback前，需要确保 LINFlexD_UART0 已经Init了。
如果进入HardFault，其行为默认也是DefaultISR。
