Hello. I am a beginner in FPGA. Also I am poor in English. Sorry. I am developing with Nexys Video. Although the design is complete, I am suffering from using QSPI Config and e-FUSE security together. I tried QSPI Config first. This worked well. Next I tried e-FUSE security. I wrote the security key and finished setting the FUSE register, After that, I could not program the QSPI. When executing the program, the following error will be displayed and will be aborted. -------------------------------------------------------------------- [Labtools 27-3165] End of startup status: LOW -------------------------------------------------------------------- You can not configure from QSPI, but you can configure an encrypted bit / bin file using JTAG. I replaced the USB cable with reference to the past forum, but there was no effect .... What does this error mean? Is there a solution for using QSPI Config and e-FUSE security together? Please tell me if you need information to solve the problem. Thank you koseki.

Hi I'm tring to program my cmod a7 35T Digilent board with an encrypted bitstream. I read that to do this i need to program the eFuse register with a key.nky file, but when i try to do this i found a problem. This board don't have a jtag connector but it can be programmed via usb. When i try to program efuse a found a problem "cannot program efuse register with this cable". Anyone can tell me if there is another way to program efuse or if this board can't support encryption bitstream? regards Stefano

Hi, I'm using Digilent's XUP USB-JTAG Programming Cable to program 'Z-turn board' which uses Xilinx Zynq-7000(http://www.myirtech.com/list.asp?id=502). There was no problem when I programed Bitstream or BBRAM through JTAG, but when I tried to program eFUSE Xilinx Vivado threw an error - ERROR: [Labtools 27-3277] jsn-DLC9LP-00000000000000 cable is not supported for EFUSE programming. Please use a Xilinx PCUSB2 DLC10 or approved Digilent cable I think my cable is approved one. Does anyone have any solution for this? Thank you in advance.
