Hi,
does the zynq device on the ZynqBerry support bitstream decryption.
In Vivado 2018.1 there is no option to encrypt the bitstream!
Best regards
Hi,
i never tried out, but normally it should be possible:

- https://www.xilinx.com/support/documentation/application_notes/xapp1239-fpga-bitstream-encryption.pdf (https://www.xilinx.com/support/documentation/application_notes/xapp1239-fpga-bitstream-encryption.pdf)
for Vivado 2018.1 see:
- https://www.xilinx.com/support/documentation/sw_manuals/xilinx2018_1/ug908-vivado-programming-debugging.pdf (https://www.xilinx.com/support/documentation/sw_manuals/xilinx2018_1/ug908-vivado-programming-debugging.pdf)
for Vivado 2018.2 see:
- https://www.xilinx.com/support/documentation/sw_manuals/xilinx2018_2/ug908-vivado-programming-debugging.pdf
on both see chapter:
- Chapter 7 Advanced Programming Features
- Appendix A: Device Configuration Bitstream Settings
or what did you mean with option is not available?

Hi John,
I have already read those guides but in Vivado when opening an implemented design and changing bitstream settings the encryption option is not listed!
When I do it via constraints file I get critical warnings.
I tried the steps above with another device and I see the encryption option in the bitstream settings!
So maybe the zynq device on the zynqberry does not support it?
Best regards
Hi,
can you send me the critical warnings or the log file.

Hi,
i think this is the same problem as yours:
