5A-75E v8.0?

[DoctorMikeReddy]

I’ve just acquired a v8.0 5A-75E board. It’s not mentioned here, and the JTAG (?) connectors are a square now, not a row. Will try to analyse over the next few days.

[DoctorMikeReddy]

Well, I’m not imagining it…

The one shown is v8.0 but with the v6 version of the JTAG connection.

Did you get it to work? I got the same one and I cannot get the JTAG to work.

Mine has been sitting in storage for months :-( as I had to move house a couple of times; divorce sucks. I’m planning to return to this over the Summer

@kargeor check the JTAG pinout for 5A-75E V6.0, it should be the same.

I got it to work. Thanks.

[DoctorMikeReddy]

Oh, what did you have to do to get it working? Anything special?

I needed to add a resistor to TDO.

anyone manage to get the full pin mapping of the 5A-75E v8.0 Board? It seems similar/overlaps to the V6 variant in the JTAG placement and other components, eg the RTL8211FD PHY and other but wanted to confirm

I also got it to work. Refer to the last message on this forum:

Here are the connections I use between the Altera USB blaster and the Colorlight 75E V8.0. I have not added any pull-up or pull down resistors.
COLORLIGHT 75E - signal - USB Blaster
J30 - TDO - 3
J32 - TDI - 9
J31 - TMS - 5
J27 - TCK - 1
J33 - 3v3 - 7
J34 - GND - 2,10

Hi, I just bought this board and I don't know much about how to configure the ini and hal files
Can you send me your configuration files?
Thanks
