    Steps to run VHWA test applications:

    cd pdk/packages/ti/drv/vhwa/

    make help

    VHWA example build

    make vhwa_msc_baremetal_testapp BOARD=j721s2_evm SOC=j721s2 CORE=mcu2_0 BUILD_PROFILE=debug

    Please note: AM62A and J722S does not support VHWA standalone test applications.

    Package Versioning

    Each package version is composed of 4 period-delimited numbers - represented here by the letters M, m, p and b [M.m.p.b]. The table below provides a descriptive reference regarding package version numbering.

    Digit Meaning Description
    1 (M=Major) Major revision Incremented when the new version is substantially different from the previous For example, a new module added or an existing module's algorithm significantly altered.
    2 (m=minor) Minor revision Incremented when the new version has changed but not in a major way. For example, some minor changes in the API or feature set.
    3 (p=patch) Patch number Incremented for all other source code changes. This include any packaging support code.
    4 (b=build) Build number Incremented for each release delivery to CM. Reset for any change to M, m or p
