Hello everyone When I use the serial port to send and receive data on imx6d and imx7d, an overrun error occurs when the serial port is sent. The

Is there a known issue with an iMX6 boot process hanging due to the UART? I have an intermittent problem on some boards where they only boot part-way until a UART cable is physically plugged in. They will spit out some Rx FIFO overrun errors for a while and then hang, e...

当我们刚上电复位Rx MailBox时,此时状态为inactive,然后激活MB,但激活后如果该MB没有收到数据,则为empty状态,此时如果收到了数据,则为full状态。在full状态,如果mcu未及时读取数据并手动将状态变回empty,然后又收到了数据,则会变成overrun状态。overrun状态时,需要不断读取MB中的数据,使得其变为full,然后empty。
