Hello,
We are developing a hardware system based on i.mx8m nano. I have a question on the RGMII/RMII interface. According to "i.MX 8M Nano Applications Processor Datasheet for Industrial Products":
On page 42:
"For RMII—ENET_TD2 functions as RMII REF_CLK when configured in the ALT1 mode."
On page 43:
"For RMII—SD1_RESET_B functions as RMII REF_CLK when configured in the ALT1 mode."
I wonder in the ALT0 mode which is the REF_CLK signal? Or is there something wrong with this datasheet?
Thanks!
Solved! Go to Solution.
Hello,
There is nothing wrong with the datasheet. It is just that for getting the REF_CLK through either pad you mentioned, it is required to use the ALT1; for ALT0 this would not be possible.
Hope it helps!
