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)
