MSP432E401Y: TI Pinmux Tool : Can't assign Ethernet pins with pinmux tool

Hi Sai,

it seems like Ethernet pins are not dedicated pins.

here is the pinmux tool result when I assigned 1 CAN and 1 EPI.

and then I followed datasheet to assign Ethernet pins.

As you can see, some pins are GPIOs(53,54,56,57,59,116,43,46). and I have a conflict on pin 59.

I think PinMux tool should handle these Ethernet pins.

Ted

Hello Ted ,

In the table that you have shown, "Pin Type" represents the direction of data flow (that is input, output or input/output). It does not represent if a signal is GPIO or not.

From the table you have shown, the signals EN0LED0, EN0LED1, EN0LED2 and EN0PPS are muxed. The other signals, EN0RXIN, EN0RXIP, EN0TXON, EN0TXOP and RBIAS are dedicated Ethernet Pins.

The pin 59 should be a dedicated Ethernet pin. Can you explain how you determined that there is a conflict with that pin?

A better place to look for Pin multiplexing is "GPIO Pin Multiplexing" section of the datasheet. Here, the dedicated Ethernet Pins should not be listed as they are not GPIOs.

Thanks,
Sai

Hi Sai,

I tried to use CAN+EPI+Ethernet with 128pin device.

the pin 59 can be also EPI0S24 when I using pinmux.

However, As I confirmed datasheet, it's dedicated ethernet pin.

pin 60 should be an EPI0S24 but something is wrong with pinmux..

I should tell the customer not to use pinmux and use datasheet to assign a pin.

Hi.

Sorry to intrude on this issue, but I have just faced exactly the same one with our design here.

The Web based and Download based PINMUX tools behave differently! The downloaded Version: 4.0.1512 (under Linux) allows you to add the Ethernet module, and then allows you to select which pins are used for the LEDs and PPS. The Web based one does not.

Hi Sai,

Customer can assign GPIOs on Ethernet dedicated pins too. please check it.
Thank you for your support.
