I'll have to check that out.

Edit: This will take some thought to have the spinbox updated from the hal pin and the hal pin updated from the spinbox without a fight as to who is in control of the value.

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.

loadrt cia402pv names=cia402pv.Spindle

Doesn't appear to be commented out in the Hal file ?

Hmm, did you by any chance comment out the loadrt cia402pv line?

Oh, you're right, I always assumed they were MII chips, like on all other FPGA boards.

Hmmm, that could make things a lot easier, since the difficult part is already in the chip.

Thank you very much!!!

Hi Hakan
Thanks for the help I have configured to the directory now, but have a new error message ?

The Ethernet chips on the mesa cards use a 16 bit bus, thought I'd mention this as you mentioned MII. From what I understand MII is supposed to be a more or less generic communication interface.

But I can get confused with these things .

Sad to say but the Aussie Gumbernment, being advised by an unelected eKaren who's main job was the keep the kids safe from rock spiders, is also responsible for this mess.
Honestly since the only reason I watch Foxtel, cable tv to our north American cousins, is to watch the MotoGP, WSBK and other bike racing, I had a YouTube Premium subscription for a few years now, maybe pre coof years. So I don't have an issue with signing in.
I think I may have seen some free to air tv a year or so ago, I lost 3/4 of my IQ felt the urge to be some crocs and a Ford Ranger and listen to Triple M on the radio...luckily I can neither afford a Ford Ranger nor a pair of crocs.

RIO now actually consists of two projects:

1. Configuration front end with HAL/INI generator

2. FPGA gateware generator


In Rio, there are now two ways to use a Mesa cards:

1. with RIO firmware/gateware (FPGA gateware generator)

Unfortunately, only those with an SPI interface. I will try again to build something that works with the MII chips when I get the chance, but it may take a while.

2. Original hm2 firmware (HAL/INI generator)
Still being tested. At the moment, only the 7c81 is supported, as I have this at home. Next will
be the 7i92.
This should actually support all cards, but in order to configure them correctly in the flow tool, you have to enter all pin positions into a file, which is simple but time-consuming.


I have already ordered a 7i92 clone from China.

If people wish to swallow the continued escalation of data mining of the populus and participating
in police states. that is for them to decide.

  But to put it simply rodw you don't have to log into forums to READ the information. At least not yet.
I wont be surprised if that changes soon as well. You know for the kids. Wont somebody please think
of the Children. So why Should I have to log in to VIEW a video, that's my point.
I am tired of the increasing collection of data on everyone not just me.
I may not be able to stop the big machine, But I don't have to help it along either.

Be in the directory were you have downloaded cia402pv.comp
and there do "sudo halcompile --install cia402pv.comp"

Easy to spot with the error messages, that helps a lot.

The post I put earlier was from trying to install the package manually, by
Trying to install from the Linuxcnc repos would break the build. And to be honest I think the Release may only reference the doc files. I'd have to check my notes for sure on that one. I may be wrong but I remember having a look through it.

The biggest issue would be a driver for the ethernet chip.
The mesa firmware uses a softcore (think very basic CPU) and that runs assembly language program to do all the hard lifting.
Ollie's original aim was to not have a softcore so there was virtually no jitter. I pretty sure I have this right.
To get this done I really think Ollie would need a 7i92 to do this.
The 7c81 was a simple task as it already had SPI, the 7i90 would be easy as well.
The thing with the Spartan 6 it's picky regarding which pin is the system clock and which is the SPI clock. I had trouble with the 7c81 clone I was working as the pin used for the system clock was different on the dev board I was using to the original mesa one.

Now that is not to say Ollie could not do it. If he could that would be pretty awesome as I have a couple of the Ethernet chips the 7i92 uses. Microchip offers free samples of their products.
