  1. Hello, I'm currently trying to generate a customized bootloader for my Zybo-Z7-20 project, which is based on the reVISION platform. From what I have understood from the Xilinx manuals, to generate a custom bootloader I need to open my project in Vivado, however I cannot select the option "Xilinx --> Vivado Integration --> Open Vivado Project" in my SDx Application (the option is greyed out). Am I missing some crucial steps? Any help would be appreciated.
  2. Thanks a lot, @JColvin the schematic helped me and I have tried to get BBRAM to work with battery attached now as described by the other poster. Unfortunately it did not work for me. Do you have any models of Zybo Z7 for which the secure boot function is supported? I am using the embedded vision bundle, and I already have an implementation I want to use for it, so I think it would be hard to switch to another board.
  3. Hello, someone else here already found out that secure boot doesn't work with zybo z7-20 since it's production silicon: The other poster got it to work by soldering a battery to the J15 port. I'd like to do that too but I'm a bit unsure how to go about it. In the manual for Zybo Z7 it says that the pins should only receive 3.3Vm but is it the same for the ports? And is there anything else specific I should take note about when selecting a battery? Does digilent produce special batteries for this kind of occasion? I'm also not sure which of the two entrances is the positive and which
  4. Thanks a lot! In that case, my device is also production silicon. @_engineermay I ask what kind of battery did you use?
  5. Hello! I'm also trying to secure boot my Zybo Z7-20 and I think I have the same problem. Is there any way I can test/confirm this without directly having to solder?
  6. Hello! Sadly I'm stuck again on something. Short pre-explanation: I have a Zybo Z7-20 Zynq-7000 with embedded vision bundle, for which I have gotten a SDx project from a predecessor which I am going to continue. I installed the project using the demo project "filter 2d live demo" from the digilent revision bundle (version 2017-4.2), and then replaced the src folder by my predecessor with that of the demo project, according to his instructions. There was no error with compiling and I flashed it onto an SD card as instructed in the revision bundle readme's. When I press the PS-SRST button a
  7. Allright, I could get back with the previous student and the issue was solved! Thank you!
  8. Hello, I have been trying to look into this more and get back in contact with my predecessor. Unfortunately I have not been able to reach him so far. I have checked the compiler in the SDx build settings, according to this it is the arm linux gnueabi gcc compiler, and the version of it (I was mistaken before) is 6.2.1, as used in the demo project the project of my predecessor is based on. I'm not really sure if I am looking in the right place, though. Thanks already for the answers so far!
  9. Hello, pardon me if this is a stupid question, I'm a student going to work on my master project/thesis with a Zybo Z7-20 Zynq-7000 ARM/FPGA SoC and only slowly learning the ropes of this. A previous student already wrote a lot of code for this and I'm trying to get the dependencies right so I can get it to run on my board, however, I am having problems with the C++ version. The program is based on the reVISION-Zybo-Z7-20 v2017.4-3 sample project, Live Video Demo for Pcam. My predecessor recommended me to use this project as a basis for the project he made and then copy/replace the source folde
