HS3 programming adaptor for Numato Mimas 2

[danmcb]

Hi - I just received my HS3 adaptor, am learning FPGA on a Numato Mimas dev board. But the Mimas has a 14 pin connector on 0.1" pitch (looks like a standard ribbon connector).

Checking the schematic against the HS3 docs, the pinout is the same.

is an adapter available? or can you give the connector type for the HS3 so I can make one?

 

thanks

Hi @danmcb,

Could you attach a link to the board you are trying to connect the JTAG-HS3 to.

thank you,

Jon

hi John - this is it :

shot of the JTAG connector from the schema also attached. For now I ordered some 14 pin connectors of each type and will make up  a lead, but obviously a  purpose-made cable would be a bit more robust.

regards

Hi @danmcb,

Here is a forum thread the deals will a similar issue with the pitch being 2.54 mm and trying to use the JTAG-HS3 which has a 2.00 mm pitch.

thank you,

Jon.

not a problem. I can make an adaptor. GND,  the 4 signal lines, and Vcc,  right?

OK, I made up  a cable, and Adept now sees the HS3 and also the FPGA - it recognises the chip as XC6SLX? - for some reason it doesn't seem to get the chip variant, so there are warnings when I select a .bit file. Bit it programs fast and without error.

 

Thanks!
