(or otherwise set). On the other hand, our current in-tree driver force enables TX/RX flow control by default, thus possibly leading to TX timeouts if the other end sends pause frames (which are not properly handled?): WARNING: CPU: 3 PID: 0 at net/sched/sch_generic.c:320 dev_...
To take evkbimxrt1050_freertos_lpuart for example, the flow control is disable by default. Using MAX485 for RS-485 circuit design, it need to enable the hardware flow control for transfer direction (TX, RX). Can you show me how to enable hardware flow control for RS-485 usage in ...

最后,由于我使用的是DB9串口,因此,我们可以再看看其引脚定义,对以上概念也会更加清晰。 由上图,我们可以知道,如果串口只接了RX、TX两个信号,那么要流控的话只能使用软流控;如果接了RX,TX,CTS ,RTS四个信号,那么可以使用硬流控或者软件流控。
This problem appeared, perhaps coincidentally as soon as I tried an OpenWRT firmware that forcibly disabled Flow Control (because of the tests related to the mediatek switch crash... but that's another story 😂) Clearly after ascertaining the inuity of a firmware without Flow Control (since ...

If you have flow control send disabled on the switch, it will not matter if you have the FAS controller set to full or send only since it will never receive a pause frame from the switch. So, either setting (full or send on) will work fine in your environment. 0 Reply chriskranz...
