[sigrok-devel] Issue with Trigger Function in sigrok-cli Using Kingst LA5016 Logic Analyzer

Hi sigrok Development Team, I am writing to report an issue I encountered while using the sigrok command-line tool with my Kingst LA5016 logic analyzer. When using PulseView (GUI), the trigger function works correctly. However, when I attempt to configure triggering via the command-line tool (sigrok-cli), the sampling starts immediately even without a trigger signal, rendering the trigger function ineffective. Both PulseView and sigrok-cli are installed from the nightly builds, and I have ensured that the logic analyzer’s firmware and bitfile are identical for both tools. Below is the log output from the command-line execution for your reference: text d:\Program Files\sigrok\sigrok-cli>sigrok-cli.exe -d kingst-la2016:conn=3.4 --config samplerate=1MHz:voltage_threshold=2.5-2.5 --channels CH0,CH1,CH2,CH3 --time 1000 --output-file D:\testwave1.sr -w -t CH0=f -l 5 sr: [00:00.000000] log: libsigrok loglevel set to 5. sr: [00:00.001000] backend: libsigrok 0.6.0-git-883c2ac/4:0:0. sr: [00:00.002000] backend: Libs: glib 2.44.1 (rt: 2.44.1/4401:1), zlib 1.2.11, libzip 1.5.2, minilzo 2.10, libserialport 0.1.1/1:0:1 (rt: 0.1.1/1:0:1), libusb-1.0 1.0.20.11003-rc3 API 0x01000104, hidapi 0.11.0-dev, libftdi 1.4. sr: [00:00.002000] backend: Host: x86_64-w64-mingw32.static.posix, little-endian. sr: [00:00.003000] backend: SCPI backends: TCP, serial, USBTMC. sr: [00:00.004000] backend: Firmware search paths: sr: [00:00.037000] backend: - C:\Users\chipon\AppData\Local\sigrok-firmware sr: [00:00.039000] backend: - C:\ProgramData\sigrok-firmware sr: [00:00.041000] backend: - C:\Users\Public\Documents\sigrok-firmware sr: [00:00.042000] backend: - d:\Program Files\sigrok\sigrok-cli\share\sigrok-firmware sr: [00:00.043000] backend: - d:\Program Files\sigrok\sigrok-cli\share\sigrok-firmware sr: [00:00.043000] backend: Sanity-checking all drivers. sr: [00:00.044000] backend: Sanity-checking all input modules. sr: [00:00.045000] backend: Sanity-checking all output modules. sr: [00:00.045000] backend: Sanity-checking all transform modules. srd: libsigrokdecode loglevel set to 5. sr: [00:00.052000] hwdriver: sr_config_list(): key 2147418112 (NULL) sdi 0000000000000000 cg NULL -> [uint32 20000, 20004] sr: [00:00.058000] usb: Found USB device (VID:PID = 77a1:01a2, bus.address = 3.4). sr: [00:00.059000] usb: Found USB device (VID:PID = 8087:0029, bus.address = 3.4). sr: [00:00.066000] kingst-la2016: Bus 3, addr 3 do not match specified filter. sr: [00:00.067000] kingst-la2016: Bus 1, addr 1 do not match specified filter. sr: [00:00.067000] kingst-la2016: Bus 4, addr 2 do not match specified filter. sr: [00:00.069000] kingst-la2016: Bus 2, addr 2 do not match specified filter. sr: [00:00.071000] kingst-la2016: Bus 3, addr 1 do not match specified filter. sr: [00:00.072000] kingst-la2016: Bus 4, addr 1 do not match specified filter. sr: [00:00.073000] kingst-la2016: Bus 2, addr 2 do not match specified filter. sr: [00:00.074000] kingst-la2016: Bus 4, addr 2 do not match specified filter. sr: [00:00.075000] kingst-la2016: Bus 2, addr 1 do not match specified filter. sr: [00:00.075000] kingst-la2016: USB enum found 77a1:01a2 at path usb/3-2, 3.4. sr: [00:00.076000] kingst-la2016: USB PID 01a2, MCU firmware 'kingst-la-01a2.fw'. sr: [00:00.078000] kingst-la2016: Manufacture date bytes 22 10 dd ef. sr: [00:00.078000] kingst-la2016: Manufacture date: 2022-10. sr: [00:00.081000] kingst-la2016: EEPROM magic bytes 0c f3 00 00 0c f3 10 ef. sr: [00:00.082000] kingst-la2016: Using secondary magic 0xc (0x10). sr: [00:00.082000] kingst-la2016: Model 'LA5016', 16 channels, max 500MHz. sr: [00:00.083000] kingst-la2016: FPGA bitstream file 'kingst-la5016a2-fpga.bitstream'. sr: [00:00.084000] kingst-la2016: Checking operation of the FPGA bitstream. sr: [00:00.087000] kingst-la2016: FPGA registers dump: bitstream check sr: [00:00.088000] kingst-la2016: 0000 ed 85 00 00 00 00 00 00 00 00 00 00 00 00 00 00 sr: [00:00.090000] kingst-la2016: 0010 aa 0f 00 00 00 00 00 00 20 32 00 00 00 00 00 00 sr: [00:00.090000] kingst-la2016: 0020 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 sr: [00:00.091000] kingst-la2016: 0030 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 sr: [00:00.092000] kingst-la2016: 0040 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 sr: [00:00.093000] kingst-la2016: 0050 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 sr: [00:00.094000] kingst-la2016: 0060 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 sr: [00:00.094000] kingst-la2016: 0070 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 sr: [00:00.095000] kingst-la2016: FPGA register: run state 0x85ed. sr: [00:00.096000] kingst-la2016: FPGA register: PWM enable 0x00. sr: [00:00.097000] kingst-la2016: Could re-use current FPGA bitstream.
