Hi all,
I'm facing several problems when trying to use my DreamSourceLab DSLogic basic
with
PulseView, i.e.:
- sometimes it does not trigger on the signal
- sometimes it triggers and captures the buffer, but the buffer is all '1'
- only some combinations of sample rate and buffer size seem to work, e.g.
20MHz and 10Msps seems to work and giving a correct capture, other settings
do not trigger and/or gives back an all '1' buffer
- sometimes it goes nuts and the capture does not stop and the buffer starts
to fill with the same repeated data infinitely and I need to unlplug and
replug to have ti working again. (I remember reading of a problem like that
on the list but I can't find it now)
I'm using latest PulseView appimage (0.5.0-git-9b8b734, libsigrok
0.6.0-git/4:0:0 (rt: 0.6.0-git-b503d24/4:0:0))
I've downloaded and installed the vendor suggested firmware following this
script:
http://sigrok.org/gitweb/?p=sigrok-util.git;a=blob;f=firmware/dreamsourcelab-dslogic/sigrok-fwextract-dreamsourcelab-dslogic
Has anyone encountered similar problems ? Can anyone suggest some solution ?
Thanks in advance for any help :-)
