Known issues

• Open Source compliance information is currently missing for this release of the M3-W graphics drivers. (Ref# J2717698)

  • target/qnx7/armle-v7/usr/bin/font-freetype
  • target/qnx7/x86/usr/bin/font-freetype

• On the R-CAR M3-W, a race-condition exists that may cause Screen to crash when Screen applications terminate. (Ref# J2521636)

Verification issues

These are the known verification issues that you may encounter when verifying your installation with this update:

• Some files in the following packages may be incompatible with this update because of a packaging error: (Ref# J2335344)

  • QNX SDP 7.0 Screen Board Support – R-Car H3 (7.0.0.SGA201702151847)
  • QNX SDP 7.0 Screen Board Support – R-car series, 3rd generation, common files (7.0 BuildID 6272)
  • QNX SDP 7.0 Screen Board Support – R-car series, 3rd generation, common files (7.0 BuildID 6442)
  The version of each of the following files:
  • screen-roguetq.so
  • screen-roguetq.so.sym
  will result in verification issues if you have one or more of the packages listed above already in your installation. You must ensure that the version of each of these files are from this QNX SDP 7.0 Screen Board Support RGX (7.0 BuildID 6529) update.

  We recommend that you do the following:

  1. Identify the version of screen-roguetq.so that you have installed on your development host (it's not necessary to identify versioning on file variants with debug symbols):

     1. Execute the use command with the -i option from your development host for the $QNX_TARGET/aarch64le/lib/dll/screen-roguetq.so file. For example:

        # use -i $QNX_TARGET/aarch64le/lib/dll/screen-roguetq.so
        							

     2. From the output of the use command, identify the version of the file in your installation. For example:

        QNX_BUILDID=(GNU)d515561258aa692cfad43755cf5fc77c
        NAME=screen-roguetq.so
        DESCRIPTION=Composition Manager Roguetq module
        DATE=2019/02/07-15:48:38-EST
        STATE=stable
        HOST=graphics-node-1
        USER=builder
        VERSION=graphics_release2.1x_be700
        TAGID=Graphics_br-21x_be-700-529
        PACKAGE=com.qnx.sdp.target.screen.board.rgx/7.0.6529.S201902071641
        							

  2. Check that the version of screen-roguetq.so you have installed is compatible with the this QNX SDP 7.0 Screen Board Support RGX (7.0 BuildID 6529) update.

     If the version of the file is com.qnx.sdp.target.screen.board.rgx/7.0.6529.S201902071641, then you may disregard any errors that QNX Software Center still reports on the QNX SDP 7.0 Screen Board Support – R-Car H3 or QNX SDP 7.0 Screen Board Support – R-car series, 3rd generation, common files packages that are related to the following files:

     • screen-roguetq.so
     • screen-roguetq.so.sym

     You may proceed to build your target images on your development host; there's no need for you to continue with any further steps to verify your installation regarding this issue.

     ---

     For any other verification issues that QNX Software Center reports, you need to investigate. If you don't have version com.qnx.sdp.target.screen.board.rgx/7.0.6529.S201902071641 of screen-roguetq.so installed, then you must proceed to the next steps to verify and repair your installation.

     ---

  3. Perform a Verify Installation on your installation.

     See the myQNX License Manager and QNX Software Center User's Guide for more information on how to verify your installation.

  4. Do not select any of the available repair actions on your Installation problems window; simply close this window by selecting Cancel.
  5. Select your Installed tab.
  6. Navigate to the QNX SDP 7.0 Screen Board Support RGX (BuildID 7.0.6529) package (e.g., by typing "rgx" in the Search field).

     If you're unable to locate QNX SDP 7.0 Screen Board Support RGX from your Installed tab, select the All tab and look for the package under the Installed: category.

  7. Right-click and select Repair on the QNX SDP 7.0 Screen Board Support RGX package.

     If you perform subsequent Verify Installation actions on your installation, you will still see verification issues. However, since you've performed the repair action, you may disregard any errors QNX Software Center still reports on the QNX SDP 7.0 Screen Board Support – R-Car H3 or QNX SDP 7.0 Screen Board Support – R-car series, 3rd generation, common files packages that are related to the following files:

     • screen-roguetq.so
     • screen-roguetq.so.sym

     ---

     For any other verification issues that QNX Software Center reports, you need to investigate.

     ---

  8. Confirm that you now have version com.qnx.sdp.target.screen.board.rgx/7.0.6529.S201902071641 of screen-roguetq.so installed on your development host.

     Do so by executing the use command with the -i option as described eariler in these procedures.

     Once you've established that you have the compatible version of screen-roguetq.so on your development host, you may proceed to build your target images.
