Dear all, I am having difficulties with my Kingst LA 5016 logic analyzer with sigrok- cli, as it will not acquire requested number of samples.
As a consequence (at least I believe it is a consequence of unexpectedly short data), I may get bunch of other errors during saving such data into files (both CSV and binary), ranging from empty files up to SIGSEGV/SIGABRT. There can also be "FRAME-BEGIN\n", "FRAME-END\n" in both CSV and binary files. Sometimes both, sometimes only one, sometimes none. There can be situations when the acquisition does not start at all, or when the acquisition ends, however the device (judging based on its LED) seams to keep acquiring. The single acquisitions (the ones long enough to be noticeable) take significantly more time with respect to official SW (not real issue, just an observation). The triggering looks also bit off, as the data clearly start away from requested triggers. Without triggering, the behavior is the same (again here, no real issue, I can live without the triggering). I use the nightly build, and the acquisition is initiated like this: sigrok-cli-NIGHTLY-x86_64-debug.AppImage --driver kingst-la2016 --channels CH0,CH1,CH2 --config samplerate=500m --samples 100m --triggers CH0=r,CH1=0,CH2=0 --wait-trigger --output-format binary --output-file [email protected] with (typical) following output: Device only sent 50001534 samples. In this particular case, the final file contains neither requested 1M nor announced 50001534 but 100001591 samples. With CSV format, the errors may look something like this: sr: output/csv: Expecting 4194304 samples, got 877880 sr: output/csv: Expecting 4194304 samples, got 879391 Device only sent 500001567 samples. or: sr: output/csv: Expecting 500058 samples, got 501513 Device only sent 501513 samples. Here is complete output from the sigrok-cli with loglevel 5: sigrok-cli-NIGHTLY-x86_64-debug.AppImage --driver kingst-la2016 --channels CH0,CH1,CH2 --config samplerate=500m --samples 10m --triggers CH0=r,CH1=0,CH2=0 --wait-trigger --output-format binary --output-file [email protected] --loglevel 5 sr: [00:00.000757] log: libsigrok loglevel set to 5. sr: [00:00.000833] backend: libsigrok 0.6.0-git-f06f788/4:0:0. sr: [00:00.001455] backend: Libs: glib 2.64.6 (rt: 2.64.6/6406:6), zlib 1.2.11, libzip 1.5.1, minilzo 2.10, libserialport 0.1.1/1:0:1 (rt: 0.1.1/1:0:1), libusb-1.0 1.0.29.11953 API 0x01000107, hidapi 0.9.0, bluez 5.53, libftdi 1.4, librevisa 0.0.20130812. sr: [00:00.001479] backend: Host: x86_64-pc-linux-gnu, little-endian. sr: [00:00.001488] backend: SCPI backends: TCP, RPC, serial, VISA, USBTMC. sr: [00:00.001495] backend: Firmware search paths: sr: [00:00.001521] backend: - /tmp/.mount_sigrokaBeLBF/usr/share/sigrok- firmware sr: [00:00.001534] backend: - /home/rad/.local/share/sigrok-firmware sr: [00:00.001549] backend: - /__w/sigrok-build/sigrok-build/sr/share/sigrok- firmware sr: [00:00.001558] backend: - /home/rad/.local/share/flatpak/exports/share/ sigrok-firmware sr: [00:00.001566] backend: - /var/lib/flatpak/exports/share/sigrok-firmware sr: [00:00.001579] backend: - /usr/local/share/sigrok-firmware sr: [00:00.001589] backend: - /usr/share/sigrok-firmware sr: [00:00.002111] backend: Sanity-checking all drivers. sr: [00:00.002136] backend: Sanity-checking all input modules. sr: [00:00.002141] backend: Sanity-checking all output modules. sr: [00:00.002155] backend: Sanity-checking all transform modules. srd: libsigrokdecode loglevel set to 5. sr: [00:00.006477] kingst-la2016: USB enum found 77a1:01a2 at path usb/1-2, 1.24. sr: [00:00.006984] kingst-la2016: USB PID 01a2, MCU firmware 'kingst- la-01a2.fw'. sr: [00:00.008011] kingst-la2016: Manufacture date bytes 24 08 db f7. sr: [00:00.008028] kingst-la2016: Manufacture date: 2024-08. sr: [00:00.009537] kingst-la2016: EEPROM magic bytes 0c f3 00 00 0c f3 10 ef. sr: [00:00.009554] kingst-la2016: Using secondary magic 0xc (0x10). sr: [00:00.009574] kingst-la2016: Model 'LA5016', 16 channels, max 500MHz. sr: [00:00.009593] kingst-la2016: FPGA bitstream file 'kingst-la5016a2- fpga.bitstream'. sr: [00:00.009603] kingst-la2016: Checking operation of the FPGA bitstream. sr: [00:00.011098] kingst-la2016: FPGA registers dump: bitstream check sr: [00:00.011114] kingst-la2016: 0000 ed 85 00 00 00 00 07 00 00 00 00 00 00 00 00 00 sr: [00:00.011127] kingst-la2016: 0010 e9 8d 5b 00 c7 c6 2d 00 50 f9 24 01 00 00 00 00 sr: [00:00.011146] kingst-la2016: 0020 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 sr: [00:00.011168] kingst-la2016: 0030 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 sr: [00:00.011189] kingst-la2016: 0040 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 sr: [00:00.011213] kingst-la2016: 0050 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 sr: [00:00.011239] kingst-la2016: 0060 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 sr: [00:00.011264] kingst-la2016: 0070 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 sr: [00:00.011458] kingst-la2016: FPGA register: run state 0x85ed. sr: [00:00.011564] kingst-la2016: FPGA register: PWM enable 0x00. sr: [00:00.011576] kingst-la2016: Could re-use current FPGA bitstream.
