Hello,
connecting an ethernet switch or PHY to PicoCore MX8MM over RGMII poseses some questions. I assume that connection will be equal like documented in PicoCore MX8MN hardware documentation. I guess that connection has to be 1:1 meaning TX and RX lines are not crossed. I guess too that ETH_SW_RST will be an output to reset the ethernet switch and ETH_SW_INTn will be an input to receive interrupt requests from the ethernet switch. Below my understanding of the RGMII interface of MX8MM.
Thank you for reply.
Best regards,
Daniel
