Hi,

Sorry for bothering you guys. I encountered some very weird thing about my N210 board.

When the board is powered up, it seems very thing works well. Actually, I can even ping this board. However, if I run any applications in the applications´╝î
such as uhd_fft´╝î uhd/siggen  in the /usr/local/bin folder, the terminal shows there are many errors as following After that, this board reset again and again for several minutes. It is very weird! Is there anyone can tell me what happened with my N210 board. Any suggestion or hint will be very appreciated. Thank you so much.

Best,

Pan
