WebIt's correct that phy-mode does not affect fixed-link. With GEM, there is no TX/RX skew from the MAC side, so users must add the delay in PHY. In the normal case (with a PHY but not a fixed-link situation), the users meed to put phy-mode = rgmii-id in the DTS node so TX/RX delay is added by the PHY. Hope this makes senese. WebNov 1, 2024 · [ 18.353779] net eth0: phy “4a101000.mdio:04” not found on slave 0, err -19. So something, somewhere, is hard-coding this address and it was just coincidence that I chose adr=4 for my second phy. 2. changing my hardware 1st PHY address to 4 (leaving 2nd phy at 0) results in the ethernet port now working (regardless of device tree setting). razr maxx hd waterproof case

WebJan 20, 2024 · Running cmd.exe : arp -a -v lists all IP addresses on the C class subnet on one of my Win 10 Pro machines (another one is fine). These are listed on my Ethernet interface on that subnet and also for an interface: 0.0.0.0 --- 0xffffffff. Disabling the Ethernet adapter and re enabling it corrects the problem for a short period, but it always ... WebTo me it looks like the enumeration of the emmc caused your SD card's block device to change. See, the emmc is coming up as mmcblk0, but your sd card is coming up as mmcblk1. You should set your root cmdline argument to mmcblk1p. chopwood (Customer) WebFeb 20, 2024 · Yes, forcing this signal to 1 indicates signal presence from the optical PHY (you can force it via this register or route the signal_detect signal from the PL). 15) How was the SGMII interface validated?
