Tutorial - Using the USB Logic Analyzer with sigrok PulseView
about a year ago
If you are using an Linux distro and are unable to connect to the Logic Analyzer you probably don't have the firmware (fx2lafw-saleae-logic.fw)
When attempting to select the LA pulseview will autodetect the device properly through the menus, but after clicking OK it will revert to "No device" without any useful GUI notification. If you run pulseview from CLI you can see the following output:
sr: resource: Failed to open resource 'fx2lafw-saleae-logic.fw' (use loglevel 5/spew for details).
sr: fx2lafw: Firmware upload failed for device 2.4 (logical).
sr: fx2lafw: Unable to get version info: LIBUSB_ERROR_TIMEOUT.
sr: fx2lafw: Failed to get firmware version.
sr: fx2lafw: Unable to open device.
From here you have two options. Install the firmware from source (or prebuilt tarball). Or Install the missing package from your OS repos.
Source can be found here:
For Fedora the package:
sudo dnf install sigrok-firmware-fx2lafw
No public wish lists :(
