USRP Warning&Error

Thread priority scheduling

When UHD software spawns a new thread, it may try to boost the thread's scheduling priority. If setting the new priority fails, the UHD software prints a warning to the console, as shown below. This warning is harmless; it simply means that the thread will retain a normal or default scheduling priority.

UHD Warning:
    Unable to set the thread priority. Performance may be negatively affected.
    Please see the general application notes in the manual for instructions.
    EnvironmentError: OSError: error in pthread_setschedparam

Overrun

什么是 USRP2 （Overrun）太慢的信息？               

当前，太慢一般是表现 UART 端口而不是主机。它被表示为“O”。 现实是你将永远无法看到这些。如果计算机太慢，你将会看到“S"信息显示在主机的终端上。它表示序列编号错误。

UnderRun

什么是 USRP2 （underrun）太快信息？                     

太快 （Under Run) 是表现在 UART 端口，被表示为“U"。
