How to run RISC-V test applications using qemu?

[Jan.Sommer at dlr.de]

Hello,

I tried to experiment a bit with the riscv BSPs.
I could run them using the SIS simulator, but failed with qemu.
Regarding qemu I found this ticket:
https://devel.rtems.org/ticket/3608

In one mailinglist thread (from 2018) someone said it worked with a current master version of qemu.
I have compiled qemu-5.1 and qemu-5.2-rc2. Does anyone know if those version have the necessary patches included?

Then another source of error could be the command line parameters I used:
qemu-system-riscv32 -nographic -machine virt -m 2G -bios none -nographic -net none -serial stdio -monitor none -kernel ticker.exe

Does someone have an example for a working set of command line options?

Best regards,

    Jan
