6i25 bitfile

Greetings,

I have a 6i25. The manual for the 6i25 states "These is a small speed advantage and some additional 6I25 features available if the card is runs as a native 6I25. To do this, a 6I25 bitfile must be loaded in the 6I25's EEPROM, and the local PCI clock set to 66MHz."

I have toggled the jumpers to set the PCI clock to 66MHz as per the manual. I cannot find the 6i25 bitfiles in the  www.mesanet.com/software/parallel/5i25.zip archive.

I have reached out to mesa requesting support, but they have not replied as of now.

Has anyone successfully loaded a 6i25 bitfile into the 6i25's EEPROM? If so, where did you get the 6i25 bit file?

Regards,

John 

Moved to "driver boards".

There is no actual advantage to using a 6I25 configuration for LinuxCNC so they have been dropped
The VHDL Source is available if you want to compile something for a non-LinuxCNC application.

Hi Peter,

Thank you for this information. Forgive me, I'm new. Are you associated with Mesa Electronics?

Yes.

Right now, the 6i25 manual states "These is a small speed advantage and some additional 6I25 features available if the card is runs as a native 6I25. To do this, a 6I25 bitfile must be loaded in the 6I25's EEPROM, and the local PCI clock set to 66MHz." The manual does not say that the 6i25 bitfile is not available, and in fact implies the opposite.

What do you think of the idea of relaying to whomever writes the documentation at Mesa Electronics a suggestion to update the documentation for the 6i25 to make this it clear that there is no 6i25 bitfile available and that someone should always use the 5i25 bit files for the 6i25?

PCW is from Mesa, most if not all the vhd code bears his name.

The thing is is not just Linuxcnc that his products are used for.

I see. Thanks for clarifying why the manual states that there are advantages to using a bitfile that is not distributed compiled in the archive of supported software that is linked to next to it on this page: store.mesanet.com/index.php?route=produc...ct_id=58&search=6i25
