Hello Champs,
HW: smart car driving system with tda4
SW: SDK7.3.0.
After enabling ENABLE_ETHFW, it will affect the sending of MCAN, causing the MCAN of the MAIN domain to fail to send messages. When ENABLE_ETHFW is not enabled, the MCAN transmission of the MAIN domain is normal, and the display effect is as shown below. 
this is the new one ,but I disable ENABLE_ETHFW,the CAN can send messge!
Thanks.
