bitbake errors pulled my hair out as well. Took me several days to get a imx-image-core build through. Finally ended up with a VM and Ubuntu 20.04, 16GB memory and 4 CPU, no changed to local.conf. and 300GB disk and about 30 all hard to understand errors that ALL were no errors by just retrying.. (another MPU64 bit vendor only took 32GB or so not sure why IMX is so big) . Attempting "full" probably goes over 300G. Just keep retrying the build !
