    Cmod A7 HW Target Shutdown

    Hi Jon, yesterday I tested again. I found another cable. Number 9 and it worked. It never disconnects with this cable. So I will take this now. I never had this kind of problems with USB cables. Maybe there is something wrong with my board. But as long as it works in this combination all is OK for me. Thanks for your help. Regards, Michael

    Cmod A7 HW Target Shutdown

    Hi Jon, I tried the Adept SW. It found and programmed the Cmod A7 ONE time ... I'm using several USB Ports. Internal and external. I also updated the FTDI Driver to Version from September last year. ... yes ONE time it started. Another time I got a blue screen. The message was driver related (IRQL_LEVEL:...) this can happen during sudden disconnects on USB. I'll try later today again. But now it is short before 3 AM in Germany Thanks for your help so far. regards, lawi

Yes, the device seems to disconnect with the dingle ling sound when connected via Vivado. If connected without acces by vivado it stays connected. I haven't tried the microblaze tutorial yet. I tried this one: Programming Guide Can the board be bricked? regards, lawi
  4. I have bought a Cmod A7 Board, which looked nice for me. One week ago I started to learn VHDL again using Vivado 2016.4. It worked nice. I used the CmodA/_Master.xdc for the constraints and the board file provided by Digilent. I made some blink led vhdl code and loaded it up directly to the FPGA. Today I wanted to continue but it seems to be very hard to program the board again. The board is recognized and sometimes I'm able to load up the bit file but the board disconnects in under 10 seconds so it is hard to select the file in this short time. I've Vivado 2016.4 on two d
