I tried this, and everything builds OK in Vitis HLS and Vivado, both 2020.2, Pynq 2.6

The accelerated function doesn't return though. It hangs on execution:

It works if I download and use the .bit file refered to in https://github.com/Xilinx/PYNQ-HelloWorld/blob/master/pynq_helloworld/notebooks/edge/resizer.bit.link for the Z2 (https://www.xilinx.com/bin/public/openDownload?filename=pynqhelloworld.resizer.pynqz2.bit).
Not with the bit file generated by the Vitis HLS and Vivado (both 2020.2) scripts.

I will try again as soon as I have a 2.7 SD made.

Are you using Pynq-Z2?

[jancumps]

Are you using Pynq-Z2?

Yes. I am using a Zynq-Z2 with Pynq2.6. I used the Zynq-Z2 folder to make the Vivado project.
I used your repository/branch for this pull request: mariodruiz:image_v2.7_2020.2

[mariodruiz]

Did you use Vivado/Vitis HLS 2020.2?

[jancumps]

Did you use Vivado/Vitis HLS 2020.2?

Correct. I used version 2020.2 for both tools. And both Vitis HLS and Vivado gave a successful build.

edit: I used this command to get the source + vitis_lib dependecies:
git clone -b image_v2.7_2020.2 https://github.com/mariodruiz/PYNQ-HelloWorld.git --recursive

PYNQ SD 2.7 has just been released. Can you please burn an SD card with the new version and try again?

[jancumps]

I will test and report back.

[mariodruiz]

Apologies, I had forgotten to push the latest changes. Please try with commit 02da054, it should work with PYNQ 2.6 and 2.7

[jancumps]

Testing ...

[jancumps]

Success !

Vitis HLS 2020.2
Vivado 2020.2
Pynq 2.6 (I will test with 2.7 later, need to get a new SD card)

[mariodruiz]

Just tested on 2.7. But, if you can double check it would be great!

Checked. It works with 2.7 too. Thank you.
