[U-Boot] TI's OMAPL138 and KSZ8876 switch on u-boot
Hello
I am trying to get a u-boot going on OMAPL138 with three port switch KSZ8873FL, that has one MII port attached to the OMAP and two 10/100BASE-FX transceivers. Up to now, the ARP packets are going out and received by the host when doing a tftp download, but the return packets from the host don't get to the EMAC MII port. Do I need to perform any configuration on KSZ8873 over I2C or MII in order to get it going? The u-boot has support for KSZ8873 but it is hard to find which board has make use of it.
Any ideas how to make the KSZ8873FL going with the u-boot?
Kind regards, Andreas

Apparently there is very little code referring to this switch, and none that configures it. Your question would be best answered with the KSZ8873FL datasheet, to see how this switch is configured by default.
Also, you should compare your hardware's eth and switch configuration to that of U-boot-supported davinci boards known to use the KSZ8873.

Amicalement,
Thank you for your reply. The switch KSZ8873MLL is detectable at the boot process and the EMAC is getting the ID value from the phy, as well as the number of the available phys on the switch. Therefore it is a bit hard to figure out which board is using it in order to use it as an example. Does anyone have use KSZ8873MLL in the u-boot? Any assistance will be very much appreciated.
Best regards, A
