We are developing a custom board based on the Beaglebone Black with one major difference; it is intended to only use WiFi, not the on-board ethernet. Is there a way to compile the Debian kernel without using the PHY?
I attempted to use Iain Hunter's base kernel for this board but cannot get around the check when the kernel boots for the davinci_mdio initialization (see attached boot log)
