  1. Hello, I'm working on the zybo z7-20 board and followed the Zybo Z7-20 Petalinux BSP Project guide on github to run linux on the zybo. All seems well however I had some apps that I needed to add to the rootfs to run. I am working with a touch screen and the two apps I used for that were evtest and tslib. after adding evtest to the rootfs it executes just fine but the tslib binary files will not and the output for them is: "sh: usr/bin/ts_test: No such file or directory". I recently did the same thing on the zynq zc702 board from xilinx and it all worked fine. i'm using the same binary files that were cross compiled for the zc702 board since its the same chip on the zc702 and the zybo. Im also working with QT to develop a UI and when i upload the qt binary to run on the zybo I get the same error that says "no such file or directory" when the file is actually there. when i run the ldd command on the files I am trying to execute it gives me "not a dynamic executable" message. I am not sure what is going on and why the binary files wont execute and is giving me the error messages. thanks for your time
  2. Thanks again @Ionel, That solved it. I was now able to build the petalinux project.
  3. thanks for the info @Ionel that again was what I needed to do. I also made sure to use the correct link for the repository. I went ahead and did the same thing for all of the digilent apps that had recipes to grab from github. I unfortunately have yet another build error ERROR: libuio-1.0-r0 do_install: oe_libinstall: unable to locate shared library ERROR: libuio-1.0-r0 do_install: Function failed: do_install I've been trying to figure this out but haven't had much success yet.
  4. thank you for your response and that did solve the problem. However, now there is another fetch being made to github.com/mitchellorsucci/libuio.git that is trying to use libuio-1.0. I have already set up the sstate-cache thats available from Xilinx for offiline builds so this seems to be something specific towards the zybo Z7-20? I noticed that the Petalinux BSP project features list has "HDMI input via UIO drivers" and the libuio library is used for interfacing for UIO devices so it seems that is what it is used for? Anyway would you have a build solution for this? I have already downloaded the library from github but am not sure what to do with it from there. thanks for your time.
  5. Hello, I'm working on setting up a Petalinux project for the zybo z7-20 on an offline computer. So far I followed the Zybo Z7-20 Petalinux BSP Project readme to set up the project however I cannot build the project due to it being configured to download two sources from github. One is downloading u-boot from git://github.com/digilent/u-boot-digilent.git and another is downloading the linux kernel from git://github.com/digilent/linux-digilent.git and since I am on an offline computer it cannot download these. Is there an option for petalinux to pull these locally and/or can I download them and place them in the petalinux project so its already there and doesnt need to be downloaded. any help with this would be appreciated, elliottal
