S32G can not send broadcast and can not recvice broadcast

S32G can not send broadcast and can not recvice broadcast，please help to check network  configure，

Hello, @liubin123

Thanks for the reply.

Since I cannot reproduce your issue from local S32GRDB2 with default images of BSP34.2, and it was mentioned previously that the RDB is used from your side, May I know have you ever tested the default pre-built images on your RDB?(you may directly download it from the www.NXP.com under your account)  Are there any issues found either?

From my opinion, this apple to apple comparison could help us to narrow the scope of root cause.

Hello, @liubin123 

I noticed that this is the similar case to the following link:

https://community.nxp.com/t5/S32G/S32G274-PFE1-cannot-send-and-receive-udp-broadcast-messages/td-p/1...

Then I may update the status in that link, which could be also for your reference.

Sorry for any inconvinience.

Best Regards

Hello, @liubin123

Thank you for the reply

1. I tested the broadcast feature with default SDK settings(pfe0 enabled, while pfe1 disabled), directly connected the pfe0 to the network interface on another machine, with the python code from user, the test is running without issues. (The PFE0 could send and receive broadcast packets correctly).

2. I will continue test with the PFE1 by modifying the configurations of the BSP default value, in order to match your testing setup, could you kindly please help to clarify the ethernet settings? It is better to have the uboot env log attached, thanks.

Best Regards

Hello, @liubin123

Thanks for the question.

May I know if you are using a RDB board or custom board? and which version BSP used when met the issue? Have you done any modifications from the software view?

Best Regards
