TopJTAG: USB JTAG HS2 GPIO Configuration

[AndyK]

Hello

I have a Digilent USBJTAG HS2 and I'd really like to use it with TopJTAG's Probe software.

The software has native support for the Digilent USB-JTAG but not the USB JTAG HS2.

Having said that, it supports "custom" JTAG probes based on the FTDI chipset and recognises the HS2 as such. This is encouraging. 

When I select the Custom FTDI option it asks me to tell it what to do with the FTDI GPIOs and advises that different probed need their GPIOs setting up differently - often to enable buffers, drive tRST, and stuff like that. Sounds fair enough to me.

The problem is that I cannot find documentation on how the GPIOs are used/configured on the HS2. The schematic would help, but the link to the schematic on the digilent website is dead.

Can anyone help with the GPIO config or a schematic of the HS2?

Many thanks.

Hi Andrew,

Unfortunately Digilent does not release the schematics for the JTAG HS2. All the information that we have available for it is on it's resource center here.

I'm sorry I could not be of more help.

Thanks,
JColvin

TBH that's not helpful at all and I expected better.

Can you at least reveal what I need to do to the GPIOs to enabled the buffers/reset/etc.?

Andy,

I emailed you some information that should help with the set up of your software.

thank you,

Hi John,

I know I am replying to an old post, but could you also share the pin configuration with me? I am having the same problem of using HS2 with TopJTAG.

Thank you!

Hi Jon,

we have the same problem of using JTAG-HS3/HS2 with TopJTAG. Can you please provide pin configuration for both HS3 and HS2?

Hi Dinko,

FYI - We didn't have luck with HS2 thus ended up using USB-JTAG from Digilent to work with TopJtag. It was just easy. Hope it helps.

Hi @dzerjav,

I PM'd you the same information I sent @8LW4.

Hi @jpeyron,

I am having the same challenge with JTAG-HS3. Could you please share pin configuration of jtag-hs3 with me.

Hello,

I also need the JTAG-HS3 pin configuration info for use with TopJTAG.

Thanks,

Hi, Thanks for everyone on the thread for bringing the topic there. Now topjtag email id are not working now(Its a Ukraine based firm), but wanted to try topjtag trial and purchase quickly as I am in a serious debug. Please share the pin configuration to me. I also need the JTAG-HS3 pin configuration info for use with TopJTAG.

Hi @john2022,

I have sent you a PM.
