S3-1 S3-2 {{ :en:arm:tqma6ulx:linux:yocto:tqma6ulx_can_loopback.png?nolink&400 |}} The STKa6ulxL Starterkit provides two Gigabit Ethernet interfaces. In U-Boot eth0 is configured as default interface. The IP configuration can be done statically or by a DHCP server in the network. Both Ethernet interfaces are activated and configured by systemd-network. The configuration files for interfaces are located in /lib/systemd/network/ these configuration files can be altered to customize the default interface configuration. | eth0 | 10-eth0.network | | eth1 | 10-eth1.network | tqma6ulxl arm 3 3 STKa6ulxL ^ Interface ^ Device tree ^ | LVDS0 | imx6ul-mba6ulx-lga-lvds.dtb | '' (e.g. ''setenv fdt_file imx6ul-mba6ulx-lga-lvds.dtb'') MBa6ulx one | SPI2 | /dev/spidev1.0 | * SPI2: bridge between X5_35 (SPI2_MOSI) and X5_36 (SPI2_MISO) The STKa6ULxL has two temperature sensors, one is located on the TQMa6ULxL SOM and the other is locates on the MBa6ULx baseboard. ^ Device ^ I²C Address ^ | TQMa6ULxL | 0x1A | | MBa6ULx | 0x19 | **Read TQMa6ULxL Temperature Sensor** cat /sys/devices/soc0/soc/2100000.aips-bus/21f8000.i2c/i2c-3/3-001a/hwmon/hwmon0/temp1_input **Read MBa6ULx Temperature Sensor** cat /sys/devices/soc0/soc/2100000.aips-bus/21f8000.i2c/i2c-3/3-0019/hwmon/hwmon1/temp1_input **Read CPU internal Temperature Sensor**\\\ The i.MX6UL CPU has an internal TMU that supports one thermal zones, it can be read by the commands below: **Thermal zone0** cat /sys/devices/virtual/thermal/thermal_zone0/hwmon2/temp1_input The MBa6ulx has two user controllable LEDs, the behavior of these LEDs can be selected by several triggers. | V900 | led1 | green | /sys/class/leds/led1 | | V901 | led2 | green | /sys/class/leds/led2 | {{ :en:arm:tqma6ulx:linux:yocto:mba6ulx_user_led.png?nolink&400 |}} /sys/devices/soc0/gpio-leds/leds led1 /sys/class/leds/led1/trigger
