Hi Leo, Thanks for the help! I did take a peek at the source but did not find that it helped me understand or fix the error. If I interpret the source correctly, "firmware" is being provided to the package as a native input. When I attempt the build without cross compiling then it does succeed... `guix build -e "(@ (gnu packages bootloaders) u-boot-pinebook-pro-rk3399)"`
However that does defeat the purpose. Why would the "firmware" native input not be available when targeting aarch64-linux-gnu? Or perhaps that is not the correct question to ask...
