Glad to hear you figured it out. > Then it switches to black screen That should mean that the graphic-card is not set up properly.=20 But additionally U-Boot, GRUB or the kernel could be hanging. :-/=20 > I'm testing this on Raspberry Pi 4. I prepared everything for a 3b monthes ago. Potentially this does not match t= he current firmware or kernel anymore or does not fit the 4. Take a look at grub-efi-bootloader-chain-raspi-64 in gnu/packages/raspberry-= pi.scm. Read the notes there. Take a look at raspi-custom-txt and the others there as well. You probably h= ave to use it to set some parameters. I use these with an older kernel: dtoverlay=3Ddisable-wifi dtoverlay=3Dvc4-fkms-v3d,cma-64 enable_uart=3D1=20 My best guess is a missing dtoverlay=3Dvc4-fkms-v3d. I just noticed that the= re is meanwhile a vc4-fkms-v3d-pi4. Try that first. There are also flavours w= ithout the f(ake). Attention with enable_uart, it is set in %raspi-u-boot-bootloader-txt to 1 a= lready. There was once a U-Boot version working without enable_uart, but the= recent one seems to require it again. If this does not help, then maybe the kernel needs to be customized. I never= heard of somone else running the linux-libre kernel on a Raspberry Pi. :-) The kernel configuration in gnu/system/examples/raspberry-pi-64.tmpl has som= e comments regarding possible customizations.
