Hello Heiko, I'm playing with px30_mini_evb_v11_20190507 board on linux 6.0.0-rc6. We have some problems on "rockchip,px30-usb2phy" driver in particular in u2phy_otg: otg-port node (px30-evb.dts). Disabling this I'm able to boot the board: &u2phy { status = "okay"; u2phy_host: host-port { status = "okay"; }; u2phy_otg: otg-port { status = "disabled"; }; }; In particular we have some problems
