S32K148EVB+TJA1101 usage issues

[Chris_Tigger]

I have the S32K148EVB and the TJA1101 Adapter Card，prepare to learn Ethernet communication. The MCU on S32k148EVB is S32K148UA，I read the datasheet，The S32K148UJ or S32K148HJ is the products supported by Ethernet，but the kit I bought is from the official website. Could I learn Ethernet with my kit at this time?

Hello @Chris_Tigger ,

yes, you can. I can't see any roadblock with your embodiment. You may start with lwip_s32k148 example.

There is also S32K148UA 176pin if Ethernet and SAI can be used at the same time.

Best Regards!

Hello @Chris_Tigger ,

Yes, I think so. You can check that very easily in file S32K148_IO_Signal_Description_Input_Multiplexing.xlsx , which is an attachment of S32K1-RM.pdf.

Best regards,

Thanks for your help,

As shown in the picture above.

I still have a question, the datasheet mentions that the S32K148UA series does not have Ethernet support, can I think that as long as it is S32K148 176pin, I can use Ethernet? The rules for the name of the product are not very well understood.

Best Regards!

Hello @Chris_Tigger ,

I thought that all S32K148 supports ENET. But the device marking shall match as well. So, your question is absolutely correct.

My S32K148EVB-Q176 board uses UJ version.

Could you share with me the whole part number?

Could you read register SDID by a debugger and share the value? 

Best regards,

The part number is FS32K148UAVLU QN20V QAC1720J,I bought it from an agent, because I was afraid that I would not be able to return it, so I didn't seal it, I could only see the part number.I hope to get an answer from you, so that I can use it with peace of mind.

Best Regards!

Hello @Chris_Tigger ,

I believe that it is OK since schematic shows UA version as well. Anyway, I'm double checking this with apps. I'll be back to you once I get a response.

I test the board in debug mode, The values of the register group can be seen in the IDE's window.Does that mean I can use the ethernet module normally?

Best Regards!

[Chris_Tigger]

Thanks very much,I pray that you can also help me test the UA version, I'm waiting for your reply online. I'm very anxious!

Thank you.

I am considering purchasing a version of the S32K148UJ. The board has been returned to the agent and is currently unavailable fot testing. but I am in mainland of China, it is most convenient to buy through an agent. Look at many,basically are S32K148UA or S32K148HA,it would be best if I could get an accurate answer here.

Hello @Chris_Tigger ,

I apologize. I escalated your query, but I didn't get reply yet.

Best regards,

Many thanks, I will buy the kit again until Ican ensure the S32K148UA or S32K148HA has the Eth support, I am sorry for that.
