Pynq2.7 - bootimage apparently made, no image files, proceeded to make other boards

Hello

I have been trying to build a pynq 2.7 image for Arty Z7-10 boards for days now.
I created a Vivado project, placed the board hardware, i exported hardware and bitstream files in the correct folder, and build runs successfully.

Here is my configuration file:

ARCH_ArtyZ7 := arm
BSP_ArtyZ7 := 
BITSTREAM_ArtyZ7 := base/base.bit
STAGE4_PACKAGES_ArtyZ7 := pynq ethernet xrt 
FPGA_MANAGER_ArtyZ7 := 1

I included bitstream in .XSA file but i also placed it in base folder. Neither worked.
I source the correct dependencies as shown in the guides on the website, and afterwards i run the build.

/git/PYNQ/sdbuild$ make BOARDS=ArtyZ7 2>&1 | tee arty_build.log

The build looks like it finishes successfully at first.

After this point strange things happen.
The first time i ran this, the whole PYNQ github repository was cloned once again into folder:
/home/haris/git/PYNQ/sdbuild/build/
and afterwards it continue to make either ZCU104 board or Pynq-Z2

I cleaned up the build, removed other board definitions (pynq z1, z2 and ZCU104), left only arty, IP and sw_repo folders and tried again. The same thing happens.

I have attached the build log file.
Does anyone have any idea why this would happen?

I also do not see any image files in build folder.

Hello I would like to reply to my own message once again since i solved this issue over the weekend.
Basically it turns out that pynq build process always loads the github repo and tries to build other boards.
The way around this is to download prebuild tarballs and provide the path to the make function.

make BOARDS=ArtyZ7 PYNQ_SDIST=/home/haris/src/pynq-2.7.0.tar.gz 2>&1 | tee ArtyZ7_build.log

This saves a lot of time and potential build errors.
Now the kicker is that only Pynq versions 2.5 and 2.6 have tar.gz files on github with the official release but for version 2.7 these files are not provided to us.
I used 2.6 tar.gz files and it worked. Build was completed and also 2.7v files are then also made in output folder. You can copy them with the img file for future builds before you do “make clean”. Since this process will take about 50GB or so.

Resulting image is about 7.5GB and if someone is interested I could upload it somewhere.

Heyo,
I’d be really thankful if you could upload your image somewhere for me to use?
Thanks!

Hi, do you still need this image?
Some websites allow to upload up to 10GB image and send it via email, they keep the file for few days only.
I have not found a good hosting for files in 7-8GB range…

Send me your email in private messages, and I will upload this image.

Hi thanks for getting back to me! Yeah I still need it, I’d appreciate if you could send it on. I’ve sent you a PM with my email there.
Cheers!

Actually I just realised that you might not be able to PM via this forum. Would you be comfortable sharing the link directly through this thread if it’s time limited, or uploading to the forum or GitHub?

Hi! Which Petalinux version did you use? I tried to build this image in the past but seems that my Petalinux version was not supported to build PYNQ
