From: Anne Macedo Date: Tue, 11 Jul 2023 00:39:58 +0000 Subject: [PATCH] sunxi: H6: Enable Ethernet on Orange Pi One Plus Enable Ethernet on Orange Pi One Plus by using the correct phy for Realtek RTL8211E instead of the Generic One. Also use CONFIG_MACPWR to turn on ethernet on startup. After this patch is applied, a few issues can be seen: - there's still a PHY reset timed out error that doesn't seem to cause any impacts to the overall connection - sometimes the emac driver times out after reset (yellow LED turns on and never blinks) For future patches: for now, CONFIG_MACPWR is the only way to enable Ethernet on boot. There's already code on the dts for using the 3v3-gmac regulator. However, it is not probed on boot, so it only starts after a "regulator status" command is issued. More details about the troubleshooting on [1].
