我正在尝试将过时的SDR USRP1与子板RFX2400结合使用。但是它没有提供任何物品。
所以，我跑了uhd_usrp_probe：
$ uhd_usrp_probe
[INFO] [UHD] linux; GNU C++ version 5.4.0 20160609; Boost_105800; UHD_3.11.0.git-94-g5964adcd
[INFO] [USRP1] Opening a USRP1 device...

[ERROR] [DBMGR] The daughterboard manager encountered a recoverable error in init.
Loading the "unknown" daughterboard implementations to continue.
The daughterboard cannot operate until this error is resolved.
LookupError: KeyError: key "0" not found in dict(i, N14adf4360_regs_t17prescaler_value_tE)
我应该如何解决该错误？
