Hi Dave,
I appreciate your response. Now the fault led has switched off. But I
couldn't see anything on the terminal using serial connection. I am getting
balckscree with a cursor only. I showed some documentations about
debricking the board. Even though, I couldn't get some of the scripts in
Maybe somebody has a clearer recollection than I do, but I think the “fault”
LED on ROACH2 boards was a bit unreliable/meaningless as an indicator of an
actual fault.
HTH,
Dave

Dear Caspers,
I am a research student at FIU. Currently working with Roach2
boards. I have a problem with roach2 board. when I connect it, the fault
LED is also switching on. I have connected the board with an ethernet also.
But it is not communicating since the RX/TX led is not blinking.
Hi all -
all these sensors can have their fault outputs masked in software; either
using linux drivers or in uboot. The faults also go away when you read the
sensor values (if I remember correctly); uboot has a sensor command which
should do this. Either have a look at the uboot code or lmsensors f
Hi Rich
Indeed that is interesting. Could you try adjusting the log-level to error or
trace in tcpborphserver with ?log-level error or ?log-level trace and see if
any additional messages are outputted when the sensors are queried?

Hi Rich. I'm pretty sure your powe
Hi Adam,
With respect to the LED, I found that the alarm was caused by the
external fans being disconnected. I was able to probe R74 through R77
to narrow it down to fans. I am operating with the board externally
cooled, not in a chassis, so the chassis fans are not connected.
Interestingl
you could try ?sensor-list from the tcpborphserver3 interface then
?sensor-value for each of the available sensors.
From USB you'd have to minicom in then look in /sys/bus/i2c/devices for board
specific sensors.
Gateware could also trigger the fault led however that would depend of what you

Perhaps that power cable has become loose ?

Hi All,
Fault LED DS27 sometimes comes on on my ROACH2. Is there a way to query
for the source of the problem, from both the USB port and ethernet
connection?
Also, my power switch sometimes does not work? Is anyone having this
sort of problem?
Thanks,
Rich
Thanks Alec!

Hi Nimish. We have fixed the fault led behavior on rev2. You will have to
update the u-boot on your board. I am working on a few other issues and
will issue instructions to do this in the next few days. But for now you
can ignore the fault led as it's reporting spurious fan errors.

Hi all:
We have Roach2 Rev2 boards and experienced similar behavior with the Fault
light. We have not used the FPGA at all yet, so cannot report on how it
affects programming the FPGA.
We are seeing Fault LED (Red) ON sometimes, and merely cycling power using
the "Power" switch on the board does
Hello all,
We are having problems with our Roach 2 and don't want to update the
Borph/uboot yet. Occasionally we get a fault light and our fpga will not
run until we power down (by pulling the plug) and then up. If we cycle
power with the power button the fault light remains, even after loading
