[Discuss-gnuradio] usrp_n200_r3_fpga.bin build error

[Rahman, Muhammad Mahboob Ur]

All,

I am trying to modify the USRP N200 FPGA so as to mute the ADC when TX section is enabled inside my flow graph. However, when I try to build the usrp_n200_r3_fpga.bin file, I get below error message which I don't understand:

Any ideas on how to fix this?

Thanks in anticipation,
