PYNQ V2.7 SD image build fail for board PYNQ-Z2

[Willy]

I suffer some permission related issues. So I unisntall Vitis & Vivado again, and install them without using root permission and put their location at ~/Xilinx just like your suggestion.

1. cd ~/PYNQ/sdbuild
2. make PREBUILT=focal.aarch64.2.7.0_2021_11_17.tar.gz BOARDS=Pynq-Z2
3. Build a lot of time, it will fail at board ZCU104
   makefile:16: recipe for target ‘bitstream’ failed
   ====================================================
   make[1]: *** [bitstream] Error 137

  =================================================

4. Remove lines in build/PYNQ/build.sh, and execute make again:
   make PREBUILT=focal.aarch64.2.7.0_2021_11_17.tar.gz BOARDS=Pynq-Z2
   Finally, I got the success result:
   

One more thanks again, briansune.
Another question, how can we compress them into the SD card image just like the below link?

BTW, in your post:

Stuck at extract yocoto

Unless people having hard time on setting up the environment: Vagrant is not a good method to setup the SD build environment. I have not investigate to the bottom but what previous engineer shows there might Virtual R/W issue during such setup. STEPS: I will suggest download 18.04.06 LTS Ubuntu from official website Create a virtual disk size about 200GB or more, set the CPU >#4, RAM >#8192 Update Ubuntu packages before setting up the PYNQ 3b) Git clone the PYNQ to /home//PYNQ 3c) sudo ch…

==================================

Step 10 update a bit:
apt-get install tftpd tftp openbsd-inetd
gedit /etc/inetd.conf
(add this) tftp dgram udp wait nobody /usr/sbin/tcpd /usr/sbin/in.tftpd /tftproot
mkdir /tftproot
chmod 777 /tftproot
/etc/init.d/openbsd-inetd restart
netstat -an | more | grep udp

===========================
The “tftproot” should be corrected to “tftpboot”, because the make script use “tftpboot” not “tftproot”.
