Sorry for the super-late answer, can you provide me more context on this? Have you started the program under a gdbserver before running your script? :)

I had the same problem. I wanted to reimplement the basic example on qemu_uboot using my own kernel and a qemu raw image containing the system files of a firmware. You can see my error below :
