Hello Peter,
this is not what I expected. I did the same as you again to be sure I was not missing something. but I get the same bad result (see below)
Are you using qemu-arm as static bin or qemu-arm as dynamic bin?
I also tested it on an another machine with another Kernel version, same result.
So, what is the difference between your environment and mine?
I send you my binary, so that you can test it directly on your machine. If it works, the issue comes within the compile phase.
Thank you for your support, again.
Best regards
Jon
