Using RMII with MityDSPL138 and L138F.
Added by Michele Canepa over 12 years ago
Hello Sirs,
I'm evaluating the possibility to use the RMII interface instead of MII in order to interface the MityDSP Card with a RMII compatible ethernet PHY, on a custom motherboard.
This option is useful for me because of pin mux issues.
My questions are:
Can I use RMII with the linux kernel?
Are there any issues?
I must configure something on the linux kernel to use RMII instead of MII for ethernet?
(so, for example, connecting the card with your predefined kernel on the new board with RMII permits me to go on the network without issues or not.)
Thank you in advance for your great help!
Best Regards,

Michele,
We have used the RMII configuration on a job. I do not recall any issues (our "experts" on this subject are currently on vac). There is a wiki page ( http://support.criticallink.com/redmine/projects/arm9-platforms/wiki/Network_configuration ) describing the use of the RMII interface on the L138/1808 based platforms.
cheers

Hi Tim,
thanks for the link.
I will try that way.
Thank you very much.

Hi Michele,
I've worked on a project using the RMII before, and as far as I remember we needed to select the correct interface as described in the link Tim provided, and we also needed an FPGA build to route some of the RMII signals. Other than that everything worked fine I'm pretty sure.
