Hi All, When running the sandbox tests, I want to know how to enable eth1 in order to be able to test network features. The following command is used to run sandbox tests. ./test/py/test.py -k testname.py I am specifically interested in running the network tests. ./test/py/test.py -k test_net.py These Python tests use test.dts device tree which does not have eth1 in it. I can replace the test.dts file with sandbox.dts to enable eth1 and run the network tests; however, I think there should be a better way to do it. Can anyone help me with this issue? When running U-Boot, the -T option could be used to tell it to use the test.dts or -D to use sandbox.dts; however, there is no such option when running test.py. Eth1 is needed in order to enable the network. Enabling the sandbox network is explained after line 250 in doc/arch/sandbox.rst. For more information, the following is the list of network interfaces when each device tree is used.

arch/sandbox/dts/sandbox.dts Net: eth0: host_lo, eth1: host_eth0, eth2: host_br1, eth3: eth@10002000

arch/sandbox/dts/test.dts Net: eth0: eth@10002000, eth5: eth@10003000, eth3: sbe5, eth6: eth@10004000, eth4: dsa-test-eth, eth2: lan0, eth7: lan1
