<label can_description>The MBa8Xx provides the CAN interfaces CAN0 and CAN1.</label>

<label can_limitation><callout type="info" icon="true">
CAN FD can not be automatically configured by systemd machine units due to a limitation in the systemd version in Yocto Zeus.

CAN FD can be enabled by the following commands in the shell:

<code>
ip link set can0 down
ip link set can0 up type can bitrate 500000 sample-point 0.75 dbitrate 4000000 dsample-point 0.8 fd on
ip link set can1 down
ip link set can1 up type can bitrate 500000 sample-point 0.75 dbitrate 4000000 dsample-point 0.8 fd on
</code>

<label ethernet_description>The STKa8Xx4 Starterkit provides two Gigabit Ethernet interfaces.</label>
<label ubootdescription>In U-Boot eth0 is configured as default interface. The IP configuration can be done statically or by a DHCP server in the network.</label>
<label linuxdescription>Both Ethernet interfaces are activated and configured by systemd-network. The configuration files for the interfaces are located in /lib/systemd/network/ these configuration files can be altered to customize the default interface configuration. </label>

**Read CPU internal Temperature Sensor**\\\
The i.MX8Xx CPU has an internal TMU that supports two thermal zones, both can be read by the commands below:  

**Thermal zone0**
<code>
cat /sys/devices/virtual/thermal/thermal_zone0/temp
</code>

**Thermal zone1**
<code>
cat /sys/devices/virtual/thermal/thermal_zone1/temp
