Hi, There is IMHO a wrong calculation of R316 (4.7k) and R317 (1k) from the over-voltage protection for the EFUSE (IC26). According to the reference manual manual of the Zybo-Z7, the maximal input voltage should be 5.7V. But that's not correct. The maximal input voltage is between 5.244V and 5.643V before the EFUSE cuts of the supply from the board. Please take a look in the datasheet from the EFUSE. The negative input from the internal comparator could be between 0.92V and 0.99V. With these two values and the current values of R316 and R317 (withou
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
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.
