Errors during a DPU software installation on PYNQ

Hi!

I have some problems in the installation of DPU-PYNQ and pynq-dpu.
When I run sudo make from DPU-PYNQ/scripts then I get:

xilinx@pynq:~/jupyter_notebooks/DPU-PYNQ/upgrade$ sudo make
bash ./check_env.sh
upgrading xrt …
++ pwd

    tar: Child returned status 2

How should I get a kernel.tgz file?

When I skipped the step and I have tried to install pynq-dpu I have got another error:

xilinx@pynq:~/jupyter_notebooks/DPU-PYNQ/upgrade$ pip3 install pynq-dpu

----------------------------------------

Command “python setup.py egg_info” failed with error code 1 in /tmp/pip-build-yk_xwyqq/pynq-dpu/

I installed build_py package, but it did not solve the problem. How should I fill all requirements?
I have a custom board based on ZynqMP and generic PYNQ v2.5 image for aarch64 architecture.

Thanks for any reply

If it is image v2.5, you should have that file in your rootfs. However, that file is not necessary since it is tarring a symbolic link. Check if you have the path /usr/src/kernel on your rootfs; if so, you are good to remove:

https://github.com/Xilinx/DPU-PYNQ/blob/master/upgrade/xrt/install.sh#L16

And proceed with the upgrade process.

Hi @rock!
I have the generic image bionic.aarch64.2.5.img. It does not contain any kernel.tgz file. The /user/src/kernel is also not available in the image. This is the reason why the script fails.

I checked a pre-built image for ZCU104 and there the files are present. With the filesystem the script works correctly.
