Seeking a person to program a Lattice MachXO2 CPLD
« on: April 25, 2026, 03:32:25 pm »
Since leaving my last employer I don't have the hardware to program a Lattice MachXO2 CPLD.  I have two different sources for the same CPLD. I would need two, maybe three copies of each CPLD.  I do have the .v and .ldf files, so its just a matter of loading it and running the programmer.  Anyone out there willing to lend a had and program these?

You need to have at least *.lpf file, since it defines mapping of the pins and other settings that affect final result a lot.

I'm not aware of any standard programmers that would support them out of the board. You need to at least specify the package type of the devices you have.

And on the board they can be programmed using a lot of adapters from FTDI dongles to Pi Pico with appropriate firmware.

I once built an altera byte blaster. Back then it was a TTL buffer on an LPT port. That was quite a while ago. Having a look at a development kit these days, it looks like not much hardware is needed for programming a MachXO2 device.
