ebti07 Posted July 5, 2021 Share Posted July 5, 2021 Hello all, I am using JTAG-HS3 with TopJTAG probe software. The software has native support for the Digilent USB-JTAG but not the USB JTAG HS3. Having said that, it supports "custom" JTAG probes based on the FTDI chipset and recognises the HS3 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 HS3. 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 HS3? Similar problem has been asked before in link with HS2: The solution has been emailed and is not available in forum. Can someone help me out here.
