[Pkg-electronics-devel] Bug#1036103: sigrok: Fails to work with AZDelivery Logic Analyzer, firmware fails to load.

Mon May 15 14:57:52 BST 2023

Source: sigrok
Version: 0.3
Severity: normal
X-Debbugs-Cc: lisandro at debian.org

Hi!

sigrok-cli and pulseview fail to capture any data using the AZDelivery
Logic analyzer. I have tried the device with some proprietary software
and works (yes, I have cleaned up the udev rules after that).

Here is some output from sigrok-cli.

$ sudo sigrok-cli --driver fx2lafw --time 3s --output-format bits --channels D2 --triggers D2=r -l  5

Failed to open device.

So the firmware seems to be failing to load.

A second run will produce:

But this might just be an artifact of the first fail.
