Hi there,
I'm working on the ROACH II and came across a problem with the snapshot
block. I put the snapshots to capture the signal from the ADC (adc5g) usign
the following configuration:
-number of samples: 2^16
-Data width: 64
- check Start delay support and Use DsP48s to implement counters.
The din comes from a bus of length 64, this are all the samples of one of
the channels of the ADC appended.
we and trig ports with a constant set to one.
This configuration has work but recent it started to througth the following
error:
Traceback (most recent call last): File "snap_shot_plot.py", line 254, in

captured."%(wait_period,bram_size)) RuntimeError: A snap block logic error
occurred or it didn't finish capturing in the allotted 2.00 seconds.
Reported 0 bytes captured.
I tried to seek the error out, but the only thing that i came across is
that the status register in the snapshot block has value 0.
Could someone give me some advice on this matter?
Greatings,
