Greetings all, I am trying to update some legacy (gnuradio 3.2 with libusrp) python code to run on the latest git release (master, Mon Sep 10 08:42:14 2012 -0700). I am using a custom FPGA image for the USRP1. The FPGA image implements additional functionality that is controlled via the FPGA user registers, such as usrp.FR_USER_0. Previously, I could access these registers in Python with the
u._write_fpga_reg(address, value) function, where u is an instantiated libusrp sink, but I can't find an equivalent function for USRP-UHD. The closest I can find is usrp.set_user_register(address, value), but this generates an exception: RuntimeError: LookupError: Path not found in tree: /mboards/0/user/regs Is there a new Python function for writing to FPGA registers? I've seen references to peek32 and poke32, but I haven't found if/where they are exposed in Python. Do I need to do something to make USRP-UHD aware of my custom registers? Does the FPGA image itself need to be changed for UHD compatibility? Thanks, Colin Stagner Missouri S&T
