3 years ago We had fix the register reserves problem, and here still exist qemu problem cause execution result errors. I commulated with the qemu team to fix them, maybe it will fix within Sep I guess, and I will keep catch this.

2 years ago @bluewww We had fix all known bugs in qemu and you can check it with the qemu support in— https://github.com/plctlab/plct-qemu/commits/plct-zfinx-dev, here is a shell for test zdinx on rv32:
