For setting it up I used the current iso debian-10.0.0-sparc64-NETINST-1.iso with standard parameters in qemu -nographic mode. I had two problems: - System was not booting beyond grub - Qemu crashed at bochs_drm The iso seems to use kernel 5.6.0-2 During installation the kernel gets updated to 5.7.0-1 Debian 5.7.6-1 (2020-06-24) Regards, Connor
