OMAPL138B-EP: RMII Ethernet Example Code / Library

Bret Stewart

Part Number: OMAPL138B-EP
Other Parts Discussed in Thread: OMAPL138, OMAP-L138

Looking around TI's resources I am able to find several code examples / libraries for using the MII ethernet interface on the OMAPL138. While the hardware datasheet indicates this device supports RMII interface too I am unable to locate any code examples. I need to use both SPI buses so RMII is my only choice - can someone please point me to RMII resources for this chip? Or are they so similar from a firmware standpoint this is redundant?

Hello Bret,

What operating system do you want to run on the OMAP-L138?

Regards,

Nick

Bare metal, should have mentioned that previously.

Hello Bret,

Please keep in mind that we can no longer provide design support for OMAP-L138 RTOS and bare metal code. I am sending your thread to another team member to point you to the existing RTOS / bare metal resources.

Regards,

Nick

I don't see anything specifically about the RMII interface here...signal to noise. Can you please be more specific in suggesting a resource for this particular issue?

Hello Bret,

Please check the PDK examples from that page:

Where are the PDK example projects?

Once you have the example projects, please check the following ones which may have example code of using the RMII:

EMAC_lcdkOMAPL138_xxx
NIMU_emacExample_xxx

Regards,

Jianzhong

P.S. please note that TI has stopped supporting PDK based bare-metal SW development as announced here. We won't be able to provide further help.
