One other thing to note is the camera related IP blocks are really only supported with Rockchip's own layer with its old forks of the kernel, U-boot, etc. Based on this presentation on Rockchip camera support at OSS EU: https://elinux.org/images/2/20/Osseu25-mriesch-rk35-camera.pdf mainline support is probably a long ways off, sadly. With respect to specific boards, we have folks using the FriendlyElec NanoPC-T6 for AGL demos, and it's seemed reasonable. Scott
