Firmware
Firmware available on Google Drive hosted by Jeremy.
You can make sure that the firmware compatible with the HGCROC is active by looking in /opt/ldmx-firmware/.
For example
[eichl008@umn-zcu102-ldmx ~]$ ls -l /opt/ldmx-firmware/
total 8
lrwxrwxrwx 1 root root 30 May 29 17:01 active -> /opt/ldmx-firmware/hcal-zcu102
drwxr-xr-x 3 root root 4096 May 29 17:01 hcal-zcu102
drwxr-xr-x 3 root root 4096 Apr 11 16:37 lpgbt-zcu102You can check the version of this firmware by inspecting the name of the installed RPM.
[eichl008@umn-zcu102-ldmx ~]$ rpm -qa '*hcal-zcu102*'
ldmxfw-hcal-zcu102-20250529_120007-10dbd92.noarch

For the Bittware card with focus on HcalBackplane or Ecal Single Module Motherboard (SMM).
Functional Fast Control and DAQ for single-link
Update for EcalSMM and prep for Fast Control and DAQ
Original, able to do basic Slow Control motions with an HcalBackplane
This firmware is for the ZCU102 optically connected to an HcalBackplane or Ecal Single Module Motherboard (SMM).
Another update to fix shifting the readout pointer now that the ECOND and HGCROC are aligned, we could observe non-empty data packets.
Update to the dual target firmware to read empty data packets from the mounted ECOND.
Original "dual target" firmware supporting access to the HGCROC via the Hcal backplane board and its lpGBTs.
For the ZCU and focused on fiberless connections where the HGCROC Board is connected directly to the ZCU.
Patched an issue with the data alignment causing nibbles of data to be shuffled within a word.
You can actually observe the bug on prior versions of the firmware. After aligning the elinks, change the idle frame and then observe the elinks.

This last command would return 0xa5274163 instead of the expected 0xa1234567.
Patched an issue where the readout pointer was not always being advanced.
