i’ve been trying lots of things to get the mainline kernel to boot on the cm3 io.
No matter what i do it always seems to hang the device right after it did “Starting kernel…” - no keyboard leds, no hdmi, no serial out
This seems to be clearly related to the kernel image itself, as i was using a known good sd card with u-boot and dtbs from the rockchip-bsp.
What are the official instructions on how to build and boot an arm64 mainline kernel? Which config is recommended?
