0x03000030 points to ephy register which H6 specification does not mention. Refer to kernel/drivers/net/phy/sunxi-ephy.c kernel/drivers/mfd/acx00-core.c and kernel/arch/arm64/boot/dts/sun50iw6p1.dtsi, if you can find linux 3.10.65 from allwinner. Ethernet don't work with linux 4.19 because of missing phy driver. My boss make me to give it up, cause wasting a lot of time. So, I have no time to transplant phy driver to linux 4.19. You can refer to H6 spercs 3.20 ATE(audio codec, tve, ephy) controller、8.8 emac and 8.13 ephy setions from Allwinner_H6 V200_User_Manual_V1.1.pdf Looking forward to you work Allwinner_H6 V200_User_Manual_V1.1.pdf @martinayotte

I met a problem that kernel showed allwiner H6 ethernet internal error. link: It is hard to loacate what makes that error occur, I wish that kernel can show my log added to drivers/net/ethernet/stmicro/stmmac/dwmac-sun8i.c. my work below: 1 Added printk to drivers/net/ethernet/stmicro/stmmac/dwmac-sun8i.c, and made patch with git format-patch, move patch to userpatchs/kernel/sunxi-next. 2 run ./compile.sh to compile armbian, I am sure that patch work, have checked drivers/net/ethernet/stmicro/stmmac/dwmac-sun8i.c after compile.sh completion 3 burn Armbian_5.71_Orangepioneplus_Ubuntu_bionic_next_4.19.13_desktop.img to sdcard, inserted sdcard in H6 board and boot The ethernet internal error log showed but the rest part not How to enable kernel show booting log? Any answer would be appriciated. Thanks a lot.

Thanks, good to know how to disable ethernet, but have to use ethernet on board. So have to find a way to fixed this bug

modified config-default.conf, changed master to sunxi-4.18 #LIB_TAG="master" # change to "branchname" to use any branch currently available. LIB_TAG="sunxi-4.18" # change to "branchname" to use any branch currently available. and compiled, found out that cache/sources/linux-mainline/orange-pi-4.19/ still being used to compiled. Does it mean kernel version is 4.19 ?

The only way I know is to modify patch which makes debug process complicated and inconvinent. Furthermore, every time I running compiles.sh, it seems that most part of source code are downloaded from scratch. That waste a lot of time. So, I wander if there is a way just to modify source code and compile. With banning patch cover and redownload source code Or, is another way to fixed this error. A guy met this error，link:https://forum.armbian.com/topic/9131-h6-after-apt-upgrade/. I can not find a way to switch kernel version to 4.18.0-rc7
