USRPB210运⾏gnuradio时FPGA固件版本冲突错误解决⽅法

事情起源于昨天拿到USRP后开始调试，结果整了⼀个下午都没解决这个问题。

昨天晚上⾃⼰思考了⼀下，觉得还是版本问题。

⾸先，uhd_find_devices和uhd_usrp_probe均可以正常运⾏，没有报错，固件正常加载，序列号也可看到。

teray@teray-X550JK:~$ uhd_find_devices

[INFO] [UHD] linux; GNU C++ version 7.5.0; Boost_106501; UHD_-0-g4e06022c

--------------------------------------------------

-- UHD Device 0

--------------------------------------------------

Device Address:

serial: 86680AA

name: Zhixun-wireless_B210

product: B210

type: b200

teray@teray-X550JK:~$ uhd_usrp_probe

[INFO] [UHD] linux; GNU C++ version 7.5.0; Boost_106501; UHD_-0-g4e06022c

[INFO] [B200] Detected Device: B210

[INFO] [B200] Loading FPGA image: /usr/local/share/uhd/images/usrp_b210_...

可以看到固件加载完全正常，但是当我们使⽤apt安装的gnuradio-companion

出现报错如下：

RuntimeError: RuntimeError: Expected FPGA compatibility number 14, but got 16:

The FPGA build is not compatible with the host code build.

Please run:

"/usr/lib/x86_64-linux-gnu/uhd/utils/uhd_images_"

⾸先遇到这个不能慌张，不要按照上⾯所提⽰的运⾏固件下载器更新固件，因为那些下载的是最新版本的固件，对解决问题没有帮助。

到官⽅git上找⼀个⽐较古⽼的版本，⽐如on 17 May 2018发布的v3.11.1.0

成功。

以上。
