Error at exporting Minized BSP 2020.2 hardware xpr

Sungwoo

When exporting 2020.2 xpr at Vivado, following error comes up.

ERROR: [Common 17-53] User Exception: Specified ip cache dir /home/training/Projects/bsp_build_tests/test_tag/minized_sbc_base/hdl/projects/minized_sbc_base_2020_2/minized_sbc_base.cache/ip does not exist. Unable to copy into Shell.

To replicate, here is steps based on Ubuntu 20.04

~/Downloads$ tar -xf minized_sbc_base_2020_2.tar.gz

$ source ~/petalinux/settings.sh
$ petalinux-create -t project -s ~/Downloads/minized_sbc_base_2020_2.bsp

At Vivado 2020.2, open project at /hardware/minized_sbc_base_2020_2/minized_sbc_base.xpr

Then File/Export/Export Platform, select Next, select Hardware, select include bitstream, select Next, Next, Finish. 
Then above error pops up.



I want to modify the design and export to xsa but the error is blocking. Any advice ?

    This bogus IP cache path is unfortunately hard-coded in the minized_sbc_base.xpr Vivado project file and is an artifact of when the Vivado project was first created in the /home/training/Projects/bsp_build_tests/test_tag/minized_sbc_base/hdl/projects/minized_sbc_base_2020_2 folder.  The only way I know to fix this is to edit the  minized_sbc_base.xpr Vivado project file and change the bogus path to be relative to where the project currently is.  Here are the steps for this:

    1. Close the project in Vivado
    2. Open the xpr file in your favorite text editor and look for the "DSAIpCacheDir" setting
    3. Change it to a relative path:
      <Option Name="DSAIpCacheDir" Val="./minized_sbc_base.cache/ip"/>
      NOTE: Be careful and don't make any other edits!
    4. Save and close the xpr file
    5. Open the project in Vivado
    6. Export the new xsa file

    BTW, Xilinx UG896 says changing this path is not possible (Ch. 2, pg. 14 "the caching directory is local to the project (project_name.ip_cache)and the location cannot be changed"), but manually changing it in the xpr file seemed to work for me.  I don't know if it may cause other problems.  Hopefully not!  Let us know if this works for you!

    Hi Tom,

    Thanks for the solution and it works !.  I put absolute path on the DSAlpCacheDir and it successfully exported xsa and futher down, 'petalinux-config --get-hw-dewscription' works also fine.  I still see issue on relative path though...
