  • Hi,

    You can apply the below patch on the top of SDK 8.1. 

    Please follow the procedure below to apply the patch:

    • Initialize a git repo at <pdkInstallPath>\packages\ti and do the initial commit
      1. cd <pdkInstallPath>\packages\ti\
      2. git init
      3. git add .
      4. git commit -m “Initial Commit”
    • Apply the patch
      1. git am 0001-C-Demo.patch

    Patch contains makerules changes to incorporate C++ build and a demo application in form of a diagnostic example.

    The patch has been validated on j721e SDK 8.1. The demo application can be built for MCU and MPU core with the following command in <pdkInstallPath>\packages\ti\build

    gmake BOARD=j721e_evm CORE=mcu1_0 CPLUSPLUS_BUILD=yes board_diag_cppTest

    gmake BOARD=j721e_evm CORE=mpu1_0 CPLUSPLUS_BUILD=yes board_diag_cppTest
