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 ~~~~~~~~~~~~~~ xku@sdr_nuc:~/workarea-uhd/uhd/host/examples/gpio/build$ uhd_usrp_probe [INFO] [UHD] linux; GNU C++ version 7.4.0; Boost_106501; UHD_3.14.0.HEAD-0-g6875d061 [INFO] [MPMD] Initializing 1 device(s) in parallel with args: mgmt_addr=192.168.20.2,type=n3xx,product=n320,serial=31A5C5A,claimed=False,addr=192.168.20.2 [INFO] [MPM.PeriphManager] init() called with device args `mgmt_addr=192.168.20.2,clock_source=internal,time_source=internal,product=n320'.
