Can't specify -memmap file #270

Hello. Thank you for both of your projects. While using PCILeech, i was able to specify -memmap mmap.txt and it read it.

While trying to do same in Python, permanently getting errors:

    vmm = memprocfs.Vmm(["-device", "fpga", "-memmap", "C:/Upload/mmap.txt"])
          ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
TypeError: Vmm.init(): Initialization of vmm failed.

    vmm = memprocfs.Vmm(["-device", "fpga", "-memmap", "C:\\Upload\\mmap.txt"])
          ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
TypeError: Vmm.init(): Initialization of vmm failed.

    vmm = memprocfs.Vmm(["-device", "fpga", "-memmap", "mmap.txt"])
          ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
TypeError: Vmm.init(): Initialization of vmm failed.

Maybe there is some different way of loading this map?

And yes, if i remove memmap option, everything works good.

Can you try:

vmm = memprocfs.Vmm(["-device", "fpga", "-memmap", "C:\\Upload\\mmap.txt", "-v", "-vv", "-printf"])

and see if you get additional debug output. I find this really curious and I should look into it, but having some debut output would be good to rule out some of the more easier to find culprits first.

Thank yo uvery much, this one worked, and pointed me to possible error. I've regenerated mmap.txt and it works, so error was in not "fully exported mmap.txt"
