imx6q enet boot speed

[[email protected]]

any ideas on how to get the imx6rex to boot (3.17 kernel) into 10/100 and not 1Gb ethernet. I have a 4 wire rj45 that it has to work on.

should have added that I added ethtool commands in rc2.d/S99 scripts and also
pre-up ethtool -s eth0 speed 100 duplex full autoneg off in the /etc/networks file The later does seem to put it into the slower speed but then the kernel never starts dhcp request.

When we needed to force the PHY to work on a specific speed, we use a tool to read / write PHY mdio registers. Try this: http://www.imx6rex.com/open-rex/soft...rals/#phy_mdio

Then just follow the PHY documentation. If you need to make it default / permanent, you can add the support into your kernel device tree.
