The microphone input is not supported in the current BSP version. X19 X20 X21 {{ :en:arm:tqma7x:linux:yocto:how_to:mba7x_audio.png?nolink&400 |}} MBa7x

DIP switch S5 is used to configure the CAN interfaces CAN0 and CAN1. S5-1 S5-2 {{ :en:arm:tqma7x:linux:yocto:tqma7x_can_loopback.png?nolink&400 |}}

The STKa7x 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 |
