Hi Heiko,

Thanks very much for the link. I got it, went to the branch, applied my patches from main denx u-boot and got it to work!

The only odd thing is, I have to do this:

regulator dev vcc_lan regulator enable

Or else I can't use the networking.

When I boot up I see:

=> regulator status Name Enabled uV mA Mode ... vcc_lan disabled - - -

I've studied all of the various rk3288*.dts* examples but have no idea why the vcc_lan does not start up upon boot. My dtsi file is below. Thanks for any help.

Cheers,

Rick
