I'm trying to debug small mips code snippets in IDA with QEMU as debugger, but only NOP instructions show when I start the process

Question

I followed the tutorial IDA Help: Debugging code snippets with QEMU.

It always worked with ARM code, but now I have to reverse some MIPS and only nops are displayed like this:

Should I adjust something on the memory map? As you can see, the code is rebased in the range of 0x8f0000000. Or is it something with the generated intermediate ELF file?

I am using the Mipsel_Malta config, cmd line is

"D:\attila\qemu\bin\qemu-system-mipsel" -S -gdb tcp::%p,ipv4 -cpu 4Km -kernel "%e".
