HAT/Cape Board DT Support


Have you implemented any mechanism to support device tree overlays for stackable capes on VIM (using ID information stored in 1-wire or I²C E²PROMs)?

This is already implemented in mainline U-Boot and Linux, but the current VIM_Nougat_V170901 release is still stuck with custom versions of U-Boot 2015.01 and Linux 3.14.29, neither of which support the standard DT overlay mechanisms. Will there be an update anytime soon? Linux 3.14 is not a maintained longterm release, so this is also bad for security reasons.

Hi BenTh.WS,

Thank you for your suggestion. DT overlay hasn’t been supported now, but we will try to support it in the future.
