SOMEIP and its Service Discovery

SOMEIP/SD and SOMEIPXF dedicated examples:

But before trying the above examples, try the following example and following the step below to get environment ready.

An example to play with:

  • NetApp: An app with SOMEIP/SD, DoIP and CAN stack together
  • NetAppT: An anti-test purpose app with SOMEIP/SD only, this is used to test SOMEIP/SD
  • CanSimulator: An app used to simulate CAN bus
# The NetApp is built with FreeRTOS+LWIP sockets
# the index of the Virtual Box Network Adaptor "Oracle"
# on my PC, it's zero, but on your PC, it's maybe not
# and please staticly configured its ipv4 address to 172.18.0.1
set PACKET_LIB_ADAPTER_NR=0
# enable PCAP dump for wireshak
set USE_PCAP=YES
scons --app=NetApp --net=LWIP --os=FreeRTOS

# The NetAppT is built with host windows sockets
scons --app=NetAppT --os=OSAL

# in 2 different pannel, launch below commands to start the apps
build\nt\GCC\NetApp\NetApp.exe
build\nt\GCC\NetAppT\NetAppT.exe

When you launch the NetApp, generally you will see below messages, please note that for the NetApp + FreeRTOS + LWIP, it's using the windows PCAP to simulate a virtual network adapter for the easy study/development process. And I find that the VirtualBox network adapter is the most stable one that works perfect. So you need to install the VirtualBox and then manually configure its ipv4 address to "172.18.0.1", as below picture shows:

vbox-ip-config

After all the applications launched, press key "s" to put SOMEIP related server/client/event group online, running for several seconds, press key "s" again to put them offline, you can see logs as below:

someip net log

And under the root directory of ssas-public, you could see net.log and wireshark.pcap.

  • net.log: A text file with logs about SOMEIP/SD
  • wireshark.pcap: a network pcap file has all the ethernet packets received or transmitted by lwip
