S32K3x4 EVAB -T172 Rev B TJA1103A PHY

[Prasanna1]

Hello,

I am working on S32K3x4EVB-T172 Rev B board with PHY TJA1103A, I am trying to configure the TJA1103A to MII mode via PIN Strapping, the information provided in schematic, user manual and PCB Layout is confusing, please see the screenshot below.

in schematic its mentioned that to configure to MII mode the register R2188 and R2190 should be populated, if i populated both then both pin will be pull down, that means it is in JTAG mode.

and also its mentioned that by default of CONFIG3 line is pull down but the Register R2190 is not mounted on the board.

I want to know which default mode is TJA1103A as per the evaluation schematics and also is it possible to configure the TJA1103A to MII mode via commands ??

Please clarify.

Thank you.

Hi,

As for the specified information, the tables should be the ones to be followed, given that the notes could have been mixed up on the production (this also refers to the default state of the CONFIGx pins). Still, we will provide this information to the respective team for them to either create a new note or publish the correct configuration and assumptions. We do apologize for this inconvenience.

As for the information you are requesting, we are seeing that TJA1103A information is under secure files, for which a secure channel is required. Please, help us either opening a ticket on NXP online services or contacting your local NXP representative/FAE for them to channel this specific inquiry to the correct medium.

Please, let us know.
