Hi,
there are several ways to get all 16 channels of a Hantek 6022bl working.
Methode one:
– copy fx2lafw-sigrok-fx2-16ch.fw to fx2lafw-saleae-logic.fw. But for me this is NOT RELIABLE:
This must be done each time you connect the Hantek to the PC!
Backup firmware
1 | cp /usr/share/sigrok-firmware/fx2lafw-saleae-logic.fw /usr/share/sigrok-firmware/fx2lafw-saleae-logic.fw.bak |
Copy 16 Channel firmware over fx2lafw-saleae-logic.fw
1 | cp /usr/share/sigrok-firmware/fx2lafw-sigrok-fx2-16ch.fw /usr/share/sigrok-firmware/fx2lafw-saleae-logic.fw |
Load firmware to the device
1 2 3 | sigrok-cli --scan ..... fx2lafw:conn=1.15 - Saleae Logic [S/N: Saleae Logic] with 16 channels: D0 D1 D2 D3 D4 D5 D6 D7 D8 D9 D10 D11 D12 D13 D14 D15 |
Then ( I ) have to copy the old firmware back
1 | cp /usr/share/sigrok-firmware/fx2lafw-saleae-logic.fw.bak /usr/share/sigrok-firmware/fx2lafw-saleae-logic.fw |
And pulsview can be started. As I said really applicable.
Methode two:
– Changing the eeprom Hantek 6022bl => To difficult, see this link
In my opinion the best way is to build an own package. But be aware that the full speed of 24Mhz is not reachable with 16 channels.
1 | michael@debdev ~ # mkdir fx2lafw-build |
Add Source repository to
1 | deb-src http://archive.ubuntu.com/ubuntu noble main restricted universe multiverse |
to
1 | /etc/apt/sources.list.d/official-package-repositories.list |
Update repository
1 2 | michael@debdev ~ # sudo apt updatemichael@debdev ~ # sudo apt install build-essential fakeroot sigrok-cli sigrok-firmware-fx2lafw pulseview |
1 2 | michael@debdev ~ # cd fx2lafw-buildmichael@debdev ~/fx2lafw-build # apt-get source libsigrok |
Install build depedencies
1 2 | michael@debdev ~/fx2lafw-build # cd libsigrok-0.5.2michael@debdev ~/fx2lafw-build/libsigrok-0.5.2 # sudo apt-get build-dep libsigrok |
Apply the patch to src/hardware/fx2lafw/api.c
1 | michael@debdev ~/fx2lafw-build/libsigrok-0.5.2 # cp src/hardware/fx2lafw/api.c src/hardware/fx2lafw/api.c.org |
Modifing src/hardware/fx2lafw/api.c. Open for edit, go to line 74 and replace
1 | 0, NULL, NULL}, |
with
1 | DEV_CAPS_16BIT, NULL, NULL}, |
To create a patch for further usage use:
1 | michael@debdev ~/fx2lafw-build/libsigrok-0.5.2 # diff -Nuar ~/software/fx2lafw-build-org/libsigrok-0.5.2/src/hardware/fx2lafw/api.c src/hardware/fx2lafw/api.c > ~/fx2lafw.patch > ~/hantek-6022bl-16ch.patch |
This creates a file like this

then update the change log

Remove sigrok and pulseview

Install libsigrok4 and libsigrokcxx4, may be you must adjust the version
1 2 3 | michael@debdev ~/fx2lafw-build # ls -l *.debmichael@debdev ~/fx2lafw-build # sudo dpkg -i libsigrok4t64_0.5.2-5.1ubuntu1_amd64.deb michael@debdev ~/fx2lafw-build # sudo dpkg -i libsigrokcxx4t64_0.5.2-5.1ubuntu1_amd64.de |
And install sigrok again
1 | michael@debdev ~/fx2lafw-build # sudo apt install sigrok-cli sigrok-firmware-fx2lafw pulseview |
Be aware that the manual installation of deb package could break some update dependencies. If happens: simply remove libsigrok4, update your system and rebuild and install a new libsigrok4.
