Other Parts Discussed in Thread: SYSBIOS
Hi all,
I have configued the TI ndk stack to get the udp packets from ecu that is running tda2px.
The ecu is sending the data through ethernet that i can verify by seeing the logs on teraterm
I am not seeing the UDP packets in wireshark on linux pc that is connected to the ecu using ethernet cable.
Both in NDK and linux machine i am configuring static ip.Please see the packets i am seeing in wireshark.
Please find the NDK configuration below and also the wiresahrk image attached.
My doubts are:
a) If we have to do some configuration on the NDK side to get UDP packets.
b) If i am seeing MDNS packets instead of UDP packets what does that verify ,does it
indicate that ecu is sending data to pc.
Regards
Mayank
