Embedded module en tqma57xx TQMa57xx arm linux yocto YOCTO Linux \\ ===== Starterkit Interfaces and Functions ===== CAN is typically not enabled in the current BSP. To enable the CAN interfaces use the following commands: ip link set can0 up type can bitrate 500000 ip link set can1 up type can bitrate 500000 DIP switches SW3 and SW4 are used to configure the CAN interfaces CAN0 and CAN1. SWx-1 SWx-2 {{ :en:arm:tqma57xx:linux:yocto:tqma57xx_can_loopback.png?nolink&400 |}} The STKa57Xx Starterkit provides two Gigabit and two 10/100 Mbit 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. All Ethernet interface are activated and configured by systemd-network. The configuration files for the eth0 interface is located in /lib/systemd/network/ these configuration file can be altered to customize the default interface configuration. | eth0 | 10-eth0.network | tqma57xx arm 0 0 MBa57xx one | SPI1| /dev/spidev1.0 | * SPI1: bridge between X56_43 (SPI1_D1) and X56_44 (SPI1_D0) The STKa57xx has one temperature sensor, located on the TQMa75xx SOM. ^ Device ^ I²C Address ^ | TQMa57xx | 0x1F | **Read TQMa Temperature Sensor** cat /sys/devices/platform/44000000.ocp/48000000.interconnect/48000000.interconnect:segment@0/48070000.target-module/48070000.i2c/i2c-0/0-001f/hwmon/hwmon0/temp1_input **Read CPU internal Temperature Sensor**\\\ The AM57xx CPU has an internal TMU that supports five thermal zones, all can be read by the commands below: **Thermal zone0** cat /sys/devices/virtual/thermal/thermal_zone0/temp **Thermal zone1** cat /sys/devices/virtual/thermal/thermal_zone1/temp **Thermal zone2** cat /sys/devices/virtual/thermal/thermal_zone2/temp **Thermal zone3** cat /sys/devices/virtual/thermal/thermal_zone3/temp **Thermal zone4** cat /sys/devices/virtual/thermal/thermal_zone4/temp The MBa57xx has two user controllable LEDs, the behavior of these LEDs can be selected by several triggers. | V70 | out0 | green | /sys/class/leds/out0 | | V69 | out1 | green | /sys/class/leds/out1 | {{ :en:arm:tqma57xx:linux:yocto:mba57xx_user_led.png?nolink&400 |}} /sys/devices/platform/leds/leds/ out0 /sys/class/leds/out0/trigger
