I would like to use the full amount of RAM on the Pico-iMX6UL kit (512 MB). The Hobbitboard Arch image uses 256 MB. What is the best way of using all the RAM?
I changed the dts file to double the RAM, compiled the dts, loaded the dtb into /boot/dtbs and reboot, but that did not work, I still get only 256 MB. I read somewhere that Arch's u-boot was patched to read the dtbs in /boot/dtbs. Is that old news?
