I am trying to build a yocto image for the PicoCore iMX8MN (nano version, not mini) with the provided yocto sources from the download section but I am getting the following error:
ERROR: imx-boot-1.0-r0 do_compile: Execution of '/fsimx8mx-nano-Y2020.11-pre/sources/yocto-fus/build/tmp/work/fsimx8mn-poky-linux/imx-boot/1.0-r0/temp/run.do_compile.8019' failed with exit code 2:

It seems that the dtb_check.sh is looking for the compiled device tree but cannot find the file. Is there something that needs to be done before trying to build an image with yocto to have the compiled device tree and if so, how exactly is this done? If not, is this a known problem and is there a solution for this?
