Ethernet (board: S32K3X4EVB-T172) _transceiver TJA1103

[imlaam]

Dear Expert,

We bought S32K3X4EVB-T172 Evaluation Board for development. (S32K3X4EVB-T172 Evaluation Board for Automotive General Purpose | NXP Semiconductors)

We are currently having problems initializing the TJA1103 transceiver. We have downloaded and installed the TCPIP stack (refer: https://www.nxp.com/webapp/swlicensing/sso/downloadSoftware.sp?catid=SW32K3-REFSW-D ) and the source code includes the Init for the TJA1103 transceiver.
But when we tried it, the code didn't work. And here is the image for the core when we debug.

Could you please help us to feedback about these cases?

Thanks,
Lam Phan

Hi,

which kind of tcpip version do you use? A tcpip stack 1.0.3 supports T172 board as per its release note

Hi,

I have addition question: Can we use MII interface for board S32K3X4EVB-T172 REV B

If yes, please tell me the method to configure a board to MII mode.

BR,

Hi,

S32K3X4EVB-T172 Hardware User Manual discussed configuration of enet interface (MII vs RMII) between board revisions in chapter 11.
Attached is short guide for LWIP example porting.

Hope it helps.
