Hi, I'm having a little trouble reading the readback registers that are on the USRP. I know that most registers are write only with their contents mirrored on the computer. The reason I want read those registers back is because of a custom unit I am testing. I currently load a custom implementation on the USRP that consists of 1 TX chain and 2 custom units, one of which feeds back information into the unused readback ports (rssi0 to rssi3). I'm able to read from the capabilities register using '_read_fpga_register(FR_RB_CAPS)' and it returns a value that makes sense. When I try reading from any other register, the value returned is consistently '0'. I'm reading the registers in a loop in case the value changes after a given amount of time. I'm not sure what to try next, can someone give me a new direction?
