TDA4VM: PROCESSOR-SDK-QNX-J721E/BSP: Screen board support package compatibility

Part Number: TDA4VM

Hello,

We are working with PSDK-RTOS-J721E 07.01.00.11 and PSDK-QNX-J721E 07.01.01.00, and our QNX SDP version is 7.1. Due to the requirements of our project, we are constrained to these versions.

We are following the TI recommendation in E2E post at https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1011331/tda4vm-the-latest-version-of-qnx-bsp, which says that "...use that QNX BSP that is listed in the SDK release notes. If an earlier, or more recent QNX BSP is required, it may function as-is or may require minor modifications to get all the ... features functional".

The release notes for our version of PSDK-QNX at https://software-dl.ti.com/jacinto7/esd/processor-sdk-qnx-jacinto7/07_01_01_00/exports/docs/release_notes_07_01_01.html#qnx-dependency specify the following buildIDs of QNX packages.

When we attempted to install these packages from the QNX Software Center, the following versions were shown to us:

com.qnx.qnx710.bsp.ti_j721e_am752x_evm   - BuildID 57
com.qnx.qnx710.target.screen.board.jacinto7 - BuildID 325

We were able to install and then downgrade the first component from buildID 57 to buildID 10.

But we are not able to locate/install the Screen board component with buildID 256. The QNX Software Center only allows the installation of Screen board component with buildID 325. We checked with our QNX support contact, and they confirmed that the Screen board component with buildID 256 is not available on their server.

How should we proceed further? Please advise.

Thanks and regards.

    Hi,

    The TI Processor SDK QNX 7.1 was verified with the QNX BSP and Screen deliverables, that are specified in the PSDK QNX 7.1 Release Notes, as have been shown above.  If more recent QNX BSP and QNX Screen deliverables are introduced, the TI S/W base will not have been verified. 

    Options are as below:

    1. Request access to the specific BSP / Screen package versions specified in the TI SDK  Release Notes from QNX.
    2. Use the newer versions of the QNX release, which will likely require minor updates to the TI SDK to function. 
    3. Upgrade to a more recent version of the TI SDK QNX, which has been verified against the updated BSP and Screen deliverables.

    Regarding option (2), in general, using the update BSP / Screen package should be fine, however integration/verification of these newer versions would need to be done.   

    Regards,

    Hello,

    We are amenable to using option (2).

    What updates are required and how to apply them?

    What is the procedure for the integration/verification of newer versions?

    Thanks and regards.

    Hi,

    If you are going to pursue option (2), it will need to be driven from your end. 

    Have you tried downloading and installing the updated revisions, what errors were seen?
