In the EVK , the ETH0 is able to ping camera and ETH1 is able to ping laptop . But However, when I attempt to ping an external IP address (e.g., 8.8.8.8) from the NXP i.MX MPlus Board, the request times out. This occurs despite the laptop being connected to the internet via Wi-Fi.

I think its based on routing preference
when the route eth0 is initially up then this issue is present .
Could you check , from my understanding i think this is due to routing (not sure) , please correct me if im wrong

HI @Kiruthik-15

I have not do any change on my site, just use the default BSP code.

Because you sail "This occurs despite the laptop being connected to the internet via Wi-Fi" you should check your vpn.
