Communication Ethernet + CAN

Buo_Nto — Tue, 27 Sep 2022 17:54:21 GMT

Good evening everyone.

I am using an MPC5748G Devkit board; my project foresees an incoming Ethernet communication with TCP protocol and a CAN outgoing communication with a control unit. I tried to merge the two example projects LWIP and CAN but I have an error, how can I proceed? Is there a guide I can follow?

Thanks a lot in advance

Hi Antonio,

no, there's no guide for such particular case. We provide only set of SDK examples and user manual:

c:\NXP\S32DS_Power_v2.1\S32DS\software\S32_SDK_S32PA_RTM_3.0.3\doc\S32SDK_MPC5748G_UserManual.pdf

Also notice that we provide only very limited support for lwip because it is open source. We can provide the support only if it is related to integration to SDK.

Regards,

Lukas

Thank you so much lukas, for your answer, my plans have changed and at the moment the idea is to have a communication between the mpc5748G and another board. Can you confirm that for the TPC / IP protocol I have to start from the LWIP example project of s32 and create my sockets through the netconn api?

Thanks in advance.

Hi,

there's a nice presentation and examples for S32K148:

I will send you the examples separately.
