lauhub Posted January 23, 2017 Posted January 23, 2017 Hello, I received a few weeks ago some new Lime2 boards. Using compiled Armbian kernel leads to a network problem: no IP is set and network does not work I have messages when connecting Ethernet cable: sun7i-dwmac 1c50000.ethernet eth0: Link is Up - 100Mbps/Full - flow control rx/tx Link is Up - 100/Full The ip a command gives: 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000 link/ether 02:02:02:cc:cc:cc brd ff:ff:ff:ff:ff:ff inet6 fefe::fe:xxx:xxx:9307/64 scope link valid_lft forever preferred_lft forever I think the problem is related to the new revision of the board as described here : Ethernet PHY is changed to RTL8211E replacing the obsolete RTL8211CL no need for kernel patches But searching through the kernel options did not give me any clue, and nothing works. What is to be done to make network up again ? Is there something to reconfigure on an existing armbian installation ? Are there some files to modify ?
lauhub Posted January 23, 2017 Author Posted January 23, 2017 Hi again, I think I have found what is not working, but I do not manage to achieve it : I need to re-compile u-boot According to this message I need to disable CONFIG_RTL8211X_PHY_FORCE_MASTER which is enabled in current u-boot configuration for A20 Lime2 eMMC This gives me the following patch: diff --git a/configs/A20-OLinuXino-Lime2_defconfig b/configs/A20-OLinuXino-Lime2_defconfig index 8fd7c64..96d9d0e 100644 --- a/configs/A20-OLinuXino-Lime2_defconfig +++ b/configs/A20-OLinuXino-Lime2_defconfig @@ -17,7 +17,7 @@ CONFIG_CMD_DFU=y CONFIG_CMD_USB_MASS_STORAGE=y # CONFIG_CMD_FPGA is not set CONFIG_DFU_RAM=y -CONFIG_RTL8211X_PHY_FORCE_MASTER=y +CONFIG_RTL8211X_PHY_FORCE_MASTER=n CONFIG_ETH_DESIGNWARE=y CONFIG_AXP_ALDO3_VOLT=2800 CONFIG_AXP_ALDO4_VOLT=2800 My problem is that it does not seem to be taken into account by u-boot compilation process So the network does not work after boot sector update with freshly compiled u-boot. After compilation I should get a file in /usr/lib/u-boot/A20-OLinuXino-Lime2-eMMC_defconfig that contains the following line: CONFIG_RTL8211X_PHY_FORCE_MASTER=n But all I get is : CONFIG_RTL8211X_PHY_FORCE_MASTER=y I noticed that a file configs/A20-OLinuXino-Lime2-eMMC_defconfig was created besides A20-OLinuXino-Lime2_defconfig I created a second patch for this file, without success. So what is the process to make modification (or patch) for this specific file which seems to be created during compilation process ?
lauhub Posted January 23, 2017 Author Posted January 23, 2017 I managed to compile without RTL8211X_PHY_FORCE_MASTER enabled by: removing the add-lime2-emmc.patch sudo mv lib/patch/u-boot/u-boot-sunxi/add-lime2-emmc.patch lib/patch/u-boot/u-boot-sunxi/add-lime2-emmc.patch.disabled editing the existing (or creating) configs/A20-OLinuXino-Lime2-eMMC_defconfig file and setting CONFIG_RTL8211X_PHY_FORCE_MASTER=n running compile.sh with FORCE_CHECKOUT=no But, I still do not have network. So now I wonder where to search
lauhub Posted January 25, 2017 Author Posted January 25, 2017 SOLVED The problem did not come from software nor installation: it is a hardware related problem I tested on another board of the same revision: everything works, network, IP, etc I made my tests with several Armbian builds on different SD/eMMC Sorry for the inconvenience
tkaiser Posted January 25, 2017 Posted January 25, 2017 The problem did not come from software nor installation: it is a hardware related problem Oh no, not RTL8211E PHY problems again. Did you had a look into this https://github.com/longsleep/linux-pine64/commit/ffe3ca5be7682bbeb0fdadede29acd4a3c888015('fixing' RTL8211E issues on Pine64+ -- would also be interesting if Ethernet works on this board if you force it into Fast Ethernet mode using ethtool)
lauhub Posted January 31, 2017 Author Posted January 31, 2017 Hi, Thanks for this answer. Do I need to apply the patch before trying ethtool ? And what are the parameters for "Fast" ethernet mode ?
