Accessing code on a Max10 FPGA

The library and common tcl files I've been given to work with use the master_write_32, master_read_32 functions pretty extensively. The arguments are "service-path", "address", and "values". The service paths were being populated by the "get_service_paths master" command so at least according to the way the existing code architecture is written it seems pretty important.

Our goal isn't to reprogram or blank the device, but to communicate with it once it has already been programmed using read and write functions. All of our existing code revolves around communicating with the fpga using these master write and read functions. I was trying to not throw the figurative baby out with the bath water because I've been having issues getting their code to work, but if there are other read/write methods I'm not considering that don't rely on the master service path then I'm all ears.
