    JTAG-SMT2-NC

    Hi @JColvin We still can`t find out the reason, we used Nexys 4 DDR to download the bitfile, Vivado could find SMT2-NC, it couldn`t find Artix-7, but the Adept still could find Artix-7 100T. Hope yours suggestion.

    JTAG-SMT2-NC

    Hi JColvin, This board is a custom board, and we turned off Adept when using Xilinx tools. We have re-installed the Digilent cable drivers for several times with several versions, but it still happened. PS: When we used the Digilent Board after re-installed, it worked good on Vivado and Adept.

    JTAG-SMT2-NC

    Hi Digilent, I used DIGILENT JTAG-SMT2-NC on my board , Now I have a strange problem!!! When I use “Digilent Adept”, I can use this module to program , As you can see, everything is right! !But! When I use VIVADO2018.3 , there are problems as shown in the figure below,The jtagsmt2 shown in the picture is because the firmware was flashed with DigilentFTDIConfig, but the situation of not flashing and flashing the firmware is the same Has anyone ever had a similar problem? Please help. Thank you!

  5. Hi digilent, My jtag smt2 is damaged, I want to know the model of this resistor so I can repair it myself.I can't find Its resistance and model in the schematic,could you help me? Thanks
  6. Thank you for taking the time to reply!This really helped me a lot.
  7. Hi Digilent, My Nexys 4 DDR couldn't be powered on and I found that the IC20 on board was disappered. However, I can't find this chip in the schematic. Could you let me know this IC's type and I will buy it to repair board myself. Thanks
  8. Thanks for this circuit. I measure every pin of the IC10, there is no output for the USR_VCC12V0 and I find that the EN pin is 1.5V, which should be 5V. This pin should be the energize for IC10 to work. However, I don't know where is the PGVCC 5V comes from.
  9. Hi, My Analog Discovery studio has -12V, 3.3V, 5V output. But no +12V ouput. I unpacked the ADS cover to find the +12V without schematic because I can't find the schematic on the official website. I want to find the power tree circuit. So I can figure out which ic gives the +12V output from the 15V input. Is it possible to let me know the part power tree circuit of +12V or let me know how to repair it?
  10. I did Debugging Connections between Olimex ARM-USB-TINY-H and Arty Board’s PMOD header to program an application on Sifive Risc-V core. Unfortunately, I failed to execute the normal program on Vivado. I think I have erased EEPROM attached to the FT2232 device on the Arty. Is there any way to get my board back to its factory Settings have make it programmable? I did it on two boards, they have the same problem. Arty-A7 100t Nexys A7 100t
