Hi everyone,The download link for the 7i89 firmware/support package on the Mesa website appears to be broken, and I couldn’t find any information about a firmware variant that includes pktuart, and I couldn't find one in the 7i96s package. Would it be possible to make a firmware for 7i96S with 7i89 connected on P1, pktuart enabled (for VFD/Modbus use) on the 7i96s ?  Thanks a lot,
tar

There is no software support package for the 7I89,as it is a passive daughtercard.

Here is firmware for a 7I96S with a 7I89 on  P1:

Hi !
I tested today the new firmware and I have error at loading. Debug file information:Note: Using POSIX realtimehm2/hm2_7i96s.0: Unsupported or inconsistent PktUART TX module (version 3)not loading driver hm2/hm2_7i96s.0: failed to parse Module Descriptor 7hm2_eth: rtapi_app_main: Invalid argument (-22)./The(Mac)Mill(er).hal:9: waitpid failed /usr/bin/rtapi_app hm2_eth./The(Mac)Mill(er).hal:9: /usr/bin/rtapi_app exited without becoming ready./The(Mac)Mill(er).hal:9: insmod for hm2_eth failed, returned -12659Stopping realtime threadsUnloading hal componentsNote: Using POSIX realtime/////////////////////////////////////I noticed that the other 7i96S firmwares use PktUART2. I tried modifying the vhd with the Efinix tools, but it seems I would need the full project sources to properly change the PktUART version and rebuild the firmware. Would it be possible to provide a version of this firmware compiled with PktUART2? It would help a lot.Thanks in advance!

Its possible but a little awkward do make new firmware with older PKTUART versions
because you need to copy files around to do it.

Can you update to current LinuxCNC  (2.9.8)

If not I can look into automating the PKTUART versioning as is done for most
modules but that is a fair amount of work.

Note that the full source is available in the 7I96S.zip file
