[USRP-users] -- GPIO on N320 --

Hi,

I’m having a problem using the front panel GPIO on an N320.  I reverted back to a standard “HG” FPGA build and compiled the GPIO example program (UHD 3.14.0).   However, when I run the example program I get the following:

Error: RuntimeError: The hardware has no gpio bank `FP0'

Is the front panel GPIO bank on the N320 called “FP0” or something else?  I did not see a reference to this in the .dts.

See below for a “uhd_uspr_probe”, “uhd_config_info” dump, and the terminal output after running ./gpio.

Thanks for any help.

Regards,
Ed Nowicki
