我执行 SDL 示例里面的 examples\ethernet\gigabit\DP83867IR_10_100_1000_MII_GMII_RGMII_Sample发现如果网络线没有接上,会卡在 while (true != Check_DP83867IR_LinkStatus()); 直到网络线接上,这样表示一开始就得把网络线接上,否则程序无法往后走,但是 tviibh8m\src\example...
Ethernet Link Status pistons7 Level 4 2 May 2023 The "low_level_init" function is called when lwip is initialized, and it is determined whether LNKSTS of "GETH_MAC_PHYIF_CONTROL_STATUS" is 1. But this "GETH_MAC_PHYIF_CONTROL_STATUS" in the user documentationIt says "This ...
However, ETHTOOL Reports the link status as yes always regardless if an ethernet cable is plugged in or not. - Boot Up - Run `ethtool eth0`, link detected reports yes with no ethernet port plugged in. Settings for eth0: Supported ports: [ ] Supported link modes: Not reported...
A control circuit is coupled to the Ethernet driver and adapted to generate the control information in response to a signal from the terminal of the driver module to which the Ethernet link status indicator is connected.doi:US20060262802Greg A. Martin...
I'm debugging an Ethernet link that fails after several hours of temperature testing. We're using the TSE core in an Arria 10, configured in the 10/100/1000Mb Ethernet MAC with 1000BASE-X/SGMII PCS configuration, with LVDS I/O. When the unit is in the failed state...

The Physical Status of a Member Interface Is Up But the Link Protocol Status Is Down Because Link Aggregation Is Not Configured on the Peer EndFault Symptom In the following figure, an Eth-Trunk interface is ...
如图所示,在非故障状态下会阻塞RPL owner端口和RPL neighbour端口以防止形成环路,同时RPL owner节点会向其所在ERPS环的其他节点周期发送NRRB R-APS报文(即Request/State取值为0000,同时Status字段的RB位取值为1,表示RPL链路处于阻塞状态),表明当前ERPS环中无故障。

This video shows how to use the Linux ethtool and U-Boot MII utilities to examine Ethernet link status on Sitara AM-class devices (AM3x, AM43x, and AM57x). This is the first debug step when you have determined that there is no network activity on an Ethernet link. This training is...
