Suvhm Posted June 7, 2020 Share Posted June 7, 2020 Hello Team, I am worked on Olimex Lime2 rev.G2 board but now olimex start delivering Rev.K board. I used the same Armbian Rev 5.35 image which is having kernel version (4.13.16-sunxi) & u-boot version v2017.09. On Rev.G2 Ethernet speed was as expected but in rev.K it is not working. By default board booted and comes with ethernet speed 100Mbps, but in this case Ethernet is not working (DHCP server unable to assign ipv4 address to eth0). Later i reduce the eth0 speed to 10Mbps it start working as expected but spped is 10Mbps Some more info about the ethernet issue which will help to understand the issue more clearly - Quote Ethernet controller Id : KSZ9031 Kernel Revision : 4.13.16-sunxi U-boot Revision : v2017.09 Dmesg log : [ 513.274671] Micrel KSZ9031 Gigabit PHY stmmac-0:01: attached PHY driver [Micrel KSZ9031 Gigabit PHY] (mii_bus:phy_addr=stmmac-0:01, irq=-1) [ 513.276751] sun7i-dwmac 1c50000.ethernet eth0: RX IPC Checksum Offload disabled [ 513.276767] sun7i-dwmac 1c50000.ethernet eth0: No MAC Management Counters available [ 513.276777] sun7i-dwmac 1c50000.ethernet eth0: PTP not supported by HW [ 513.277069] IPv6: ADDRCONF(NETDEV_UP): eth0: link is not ready [ 515.363349] sun7i-dwmac 1c50000.ethernet eth0: Link is Up - 100Mbps/Full - flow control rx/tx [ 515.363397] IPv6: ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready Command to reduce the speed : "ethtool --change eth0 speed 10 duplex full autoneg on" eth0 info : Settings for eth0: Supported ports: [ TP MII ] Supported link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Half 1000baseT/Full Supported pause frame use: Symmetric Receive-only Supports auto-negotiation: Yes Advertised link modes: 10baseT/Full Advertised pause frame use: No Advertised auto-negotiation: Yes Link partner advertised link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full Link partner advertised pause frame use: Symmetric Receive-only Link partner advertised auto-negotiation: Yes Speed: 10Mb/s Duplex: Full Port: MII PHYAD: 1 Transceiver: internal Auto-negotiation: on Supports Wake-on: d Wake-on: d Current message level: 0x0000003f (63) drv probe link timer ifdown ifup Link detected: yes iperf3 log : Connecting to host 10.42.0.1, port 5201 [ 4] local 10.42.0.89 port 54528 connected to 10.42.0.1 port 5201 [ ID] Interval Transfer Bandwidth Retr Cwnd [ 4] 0.00-1.00 sec 1.18 MBytes 9.89 Mbits/sec 0 29.7 KBytes [ 4] 1.00-2.00 sec 1.06 MBytes 8.92 Mbits/sec 0 29.7 KBytes [ 4] 2.00-3.00 sec 1.03 MBytes 8.66 Mbits/sec 0 29.7 KBytes [ 4] 3.00-4.00 sec 1.12 MBytes 9.43 Mbits/sec 0 29.7 KBytes [ 4] 4.00-5.00 sec 1.09 MBytes 9.18 Mbits/sec 0 29.7 KBytes [ 4] 5.00-6.00 sec 1.09 MBytes 9.17 Mbits/sec 0 29.7 KBytes [ 4] 6.00-7.00 sec 1.15 MBytes 9.68 Mbits/sec 0 29.7 KBytes [ 4] 7.00-8.00 sec 1.09 MBytes 9.17 Mbits/sec 0 29.7 KBytes [ 4] 8.00-9.00 sec 1.09 MBytes 9.17 Mbits/sec 0 29.7 KBytes [ 4] 9.00-10.00 sec 1.09 MBytes 9.17 Mbits/sec 0 29.7 KBytes - - - - - - - - - - - - - - - - - - - - - - - - - [ ID] Interval Transfer Bandwidth Retr [ 4] 0.00-10.00 sec 11.0 MBytes 9.25 Mbits/sec 0 sender [ 4] 0.00-10.00 sec 11.0 MBytes 9.20 Mbits/sec receiver iperf Done.

Suvhm Posted June 18, 2020 Author Share Posted June 18, 2020 Thanks Igro for your prompt respond and sorry for delay in my side. Actually i have decided to change the base code and update the ubuntu version from xenial to bionic, similarly for kernel and uboot version . Now i had pulled the latest armbian SD-card image that works for me, but when i tried to port my application i found GPIO 67 is showing that device is already busy. I had used GPIO 67 in my application for rev.G board it was working fine, but when i try to port the same application on latest revision of board(rev.L) it through an error that device is busy.Steps : Tried to expose the control of gpio 67 from kernel to user space (echo 67 > /sys/class/gpio/export) Trying to set the direction, but unfortunately in the above step it shows device is busy Quote root@suvhm:~# cat /sys/kernel/debug/gpio gpiochip0: GPIOs 0-287, parent: platform/1c20800.pinctrl, 1c20800.pinctrl: gpio-67 ( |ahci-5v ) out hi gpio-80 ( |reset ) out hi ACTIVE LOW gpio-81 ( |usb0-vbus ) out lo gpio-192 ( |sysfs ) out lo gpio-193 ( |sysfs ) out lo gpio-225 ( |cd ) in lo IRQ ACTIVE LOW gpio-226 ( |a20-olinuxino-lime2:) out hi gpio-227 ( |usb2-vbus ) out hi gpio-228 ( |usb0_id_det ) in hi IRQ gpio-229 ( |usb0_vbus_det ) in lo IRQ gpio-230 ( |usb1-vbus ) out hi It seems GPIO 67 is already taken by some module/driver. here we can check some "ahci-5v" is taken the 67 no GPIO. Any help to understand what all changes had been done in latest rev.l board in GPIO perspective.
