Ethernet on Zephyr UOS

[marjano89]

Hi, I am struggling with setting up network on Zephyr UOS under ACRN. I am building simple MQTT client app which shall subscribe to broker which is installed in my LAN.

First problem was that there was not net interface:

[00:00:00.000,000] <err> net_if: There is no network interface to work with! [00:00:00.090,000] <inf> net_config: Initializing network [00:00:00.090,000] <err> net_config: No network interfaces [00:00:00.090,000] <err> net_config: Network initialization failed (-19) [00:00:00.110,000] <err> mqtt_client: Failed to subscribe to test item

I edited simple config to support ETH_E1000 which leads to compilation errors.

My config looks like this

CONFIG_NETWORKING=y
CONFIG_NET_SOCKETS=y
CONFIG_NET_TCP=y
CONFIG_NET_LOG=y

CONFIG_PRINTK=y
CONFIG_STDOUT_CONSOLE=y

CONFIG_ENTROPY_GENERATOR=y
CONFIG_TEST_RANDOM_GENERATOR=y

# Enable IPv6 support
CONFIG_NET_IPV6=n
# Enable IPv4 support
CONFIG_NET_IPV4=y

# Enable the MQTT Lib
CONFIG_MQTT_LIB=y

CONFIG_NET_CONFIG_SETTINGS=y

CONFIG_NET_CONFIG_MY_IPV4_ADDR="192.168.2.13"
CONFIG_NET_CONFIG_PEER_IPV4_ADDR="192.168.2.10"

CONFIG_MAIN_STACK_SIZE=2048

# For IPv6
CONFIG_NET_BUF_DATA_SIZE=256

CONFIG_NET_L2_ETHERNET=y
#CONFIG_NET_QEMU_ETHERNET=y

CONFIG_ETH_E1000=y

CONFIG_PCIE=y

build errors:

Does it means there is no network driver for ACRN or my config is broken?

When I build for qemu_x86, it builds without error but when I run app on ACRN, I have following output:

[00:00:00.000,000] <err> net_if: Iface 0x0012b220 driver API init NULL
[00:00:00.000,000] <inf> net_config: Initializing network
[00:00:00.000,000] <inf> net_config: IPv4 address: 192.168.2.13

Please help me solve the issue. Any kind of example Zephyr app using LAN would be useful.

@marjano89 We haven't enable Ethernet for pre-launched Zephyr UOS.

Hi @fuzhongl , is it a simple case of modifying the ACRN configuration to assign the Ethernet device to the Zephyr User VM, or is there more needed there?

I also suppose that the Zephyr Ethernet needs to support the Ethernet controller on the board, and I don't know if that's the case.

[marjano89]

Is there any possibility to add this support? I am working under SDC2 project with Zephyr as an application part which shall be a data provider for AGL UOS (Instrument Cluster ) and Celadon (IVI) and Zephyr is a key part.

I will also give a warm welcome for Ethernet support. Can you enable it? I'm preparing a demo for CES 2020 https://www.ces.tech/
