5A-75E v8.0? #73

Open DoctorMikeReddy opened 3 years ago

DoctorMikeReddy commented 3 years ago

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. D0E28083-73AB-48A9-BC3B-EC23FECBA7E0 B2834D93-EC29-4ECC-9E15-4F2C765B549D

Well, I’m not imagining it… https://www.lednets.com/upload/Support/5A-75E-Specification%C2%A0V8.0091586.pdf 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.

DoctorMikeReddy commented 3 years ago

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.

kargeor commented 3 years ago

I got it to work. Thanks.

DoctorMikeReddy commented 3 years ago

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

kargeor commented 3 years ago

https://github.com/trabucayre/openFPGALoader/issues/88 I needed to add a resistor to TDO.

WhichWayWazzit commented 2 years ago

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: https://forum.linuxcnc.org/27-driver-boards/47028-my-notes-flashing-litex-cnc-on-a-colorlight-5a-75e-solved?start=10 [root@cedric cedric]# pacman -S openfpgaloader [cedric@cedric ~]$ openFPGALoader -c usb-blaster -m LiteX-CNC/5a-75e/gateware/colorlight_5a_75e.bit write to ram Open file: DONE Parse file: DONE Enable configuration: DONE SRAM erase: DONE Loading: 100.00% Done Disable configuration: DONE [cedric@cedric ~]$

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
