Hello, I am using an X310 and I need to monitor a signal out of GPIO from my custom block. Going through the archives I prefer the option to disconnect the fp_gpio lines from the radio core to my custom block. So I snapped the fp_gpio lines going in gpio_attr to a custom module in db_control to observe the signal. The image compiled fine. But when I probe the device, I get the following error
[INFO] [UHD] linux; GNU C++ version 5.4.0 20160609; Boost_105800; UHD_3.14.0.HEAD-110-g6af6ac32 [INFO] [X300] X300 initialization sequence... [INFO] [X300] Maximum frame size: 8000 bytes.

Any help will be appreciated. Thank you, Pratik
