[Openbts-discuss] "assuming TRX is dead"

[Jie M <jie...@gm...>]

Hi all,

Just wondering if anyone can shed a bit of light on this issue I'm having.
Here's a dump from the console:

Aborted
------------------------------------------
The failures I'm interested in are RXTUNE, POWERON, SETPOWER and the TRX
clock interface time out.

My USRP 1 has two RFX900 daughterboards fitted and no external clock. When
these boards are swapped, the issue above does not occur. Originally both
boards were functioning correctly, I'm just wondering exactly what has
failed. I don't want to break both the RFX900s!

Regards,

Jie
