Hello, Thanks for your quick response! Actually, I have GNU radio flow graph as per my application which runs through UHD USRP sink and UHD USRP source to USRP B200 mini hardware, right. But now as you said we can use USB to serial converter for transmitting data from outside source. but for that, I need to dump the GNU radio flow graph into FPGA right?(that means I have to run GNU radio application on board itself without the use of host computer) So, Can you please guide me on the following (1) How can I run GNU radio flow graph on USRP B200 mini itself(without the use of host computer) or I have to dump the python code that GNU radio generates?
thanks for your support in advance.

You could expose the "user regs" to read/write to a serial peripheral which you would have to add to the FPGA. This feature (the user i/o regs) is only present in the newest version of UHD (3.14), so you will have to build UHD from the master branch as well as rebuild the FPGA. https://files.ettus.com/manual/md_usrp3_build_instructions.html https://files.ettus.com/manual/page_usrp_b200.html#b200_customfpga However, if you merely need serial i/o, a much easier solution is to use a USB to serial converter. You should think about ways to make this work before modifying the FPGA. -- Martin K.
