But it must be something with uboot related since it's not the kernel printing the error message. It's likely just an infrastructure problem on my side. Properly related to the kernel size: -rw-r--r-- 1 wagi users 31910400 Aug 26 12:54 rpi3-image-ll-v5.9-rc2-rt1-rebase-1-gdf6b97f22351 -rw-r--r-- 1 wagi users 31910400 Aug 26 12:49 rpi3-image-nohz-v5.9-rc2-rt1-rebase-1-gdf6b97f22351 -rw-r--r-- 1 wagi users 32891392 Aug 26 12:47 rpi3-image-none-v5.9-rc2-rt1-rebase-1-gdf6b97f22351 -rw-r--r-- 1 wagi users 38224384 Aug 26 12:45 rpi3-image-rt-v5.9-rc2-rt1-rebase-1-gdf6b97f22351 -rw-r--r-- 1 wagi users 31910400 Aug 26 12:54 rpi3-image-up-v5.9-rc2-rt1-rebase-1-gdf6b97f22351 -rw-r--r-- 1 wagi users 32891392 Aug 26 12:52 rpi3-image-vp-v5.9-rc2-rt1-rebase-1-gdf6b97f22351 The -rt kernel is roughly 6MB larger. Just need to check the memory ranges u-boot is using.
