Part Number: TM4C129DNCZAD
Other Parts Discussed in Thread: DP83TD510E
Tool/software:
Hi experts,
I would like to use the external RMII to attach an SPE Phy ( DP83TD510E) on our recent design with TM4C129.
To communicate with with an FPGA I am using EPI to interface with an FPGA.
I cannot find the RMII pins in the pin-table.
Can you help with checking if both can be used in parallel ?
Is there a miss from my side to find a way to see the MII signals in the pintable ?
Regards,
Alex
Hi Alex,
You can use the TI PinMux Tool to check for conflicts. I can see 5 conflicts between MII/RMII and EPI pins. For example, EPI0S8 for EPI is mapped to pin V5. However, EN0RXCK for Ethernet module is also mapped to V5.
Hi Alex,
The conflicted signals on the EPI are S8, S31, S32, S25 and S24. Refer to the datasheet for these signals for GP mode. As you can see S8 is used for D8. Will you need D8 on your FPGA. Look at S31 is for Clock. Will you need clock for your FPGA? If you don't needs these signals then it may work.
