I am trying to build a pynq v3.0.1 image. All software version are correct. When i make my own board, an error happened:
+ sudo mount -o bind /proc /home/xkl/Desktop/PYNQ/sdbuild/build/jammy.ALNX7020/proc
mount: /home/xkl/Desktop/PYNQ/sdbuild/build/jammy.ALNX7020/proc: mount point does not exist.
make: *** [Makefile:374: /home/xkl/Desktop/PYNQ/sdbuild/build/ALNX7020.tar.gz] Error 32
I have no idea for the error. I used to make a pynq v2.4 image successfully, but never meet this problem at that time.
