Steps for incremental update and debug

The following steps are to be done, when you want to incrementally update the code and run the updated binaries.

Step 1 : Change Code

  • Edit/Update the code as needed.

Step 2 : Recompile & Build the code

  • Recompile and build the code after making the changes
    cd ${PSDKR_PATH}/sdk_builder
    ./make_sdk.sh
    Note
    This builds the SDK in release mode.
    OR
    cd ${PSDKR_PATH}/sdk_builder
    PROFILE=debug ./make_sdk.sh
    Note
    This builds the SDK in debug mode, in case you want to use gdb (linux) or CCS to debug the programs.
    "make_sdk.sh" rebuilds not just the linux/QNX programs but also the remote cores. So if code is changed on those remote cores, make_sdk.sh is needed to rebuild it.
    Warning
    Make sure that there are no compiler/linker issues, after doing this step.
    Note
    To run in PC Emulation mode, now you can follow the steps mentioned in Running the vision apps demos in PC emulation mode
    To run on EVM, you can follow the steps given below.

Step 3a : Copy executable files to SD card (Linux+RTOS mode)

Note
make sure you have already prepared the sd card and copied the test data as mentioned in Run vision apps on EVM in Linux+RTOS mode (via SD card boot)
  • Insert the SD card onto your host PC SD card slot, (if not already inserted).
  • Do below to copy vision apps binaries to SD card
    cd ${PSDKR_PATH}/sdk_builder
    make linux_fs_install_sd
    Note
    This loads the release versions of all the files
    OR
    cd ${PSDKR_PATH}/sdk_builder
    make linux_fs_install_sd PROFILE=debug
    Note
    This loads the debug versions of all the files in case you want to use gdb (linux) or CCS to debug the programs
    OR
    cd ${PSDKR_PATH}/sdk_builder
    make linux_fs_install_sd HS=1
    Note
    This loads the release versions of all the files, and installs the signed firmware binaries as required for an HS platorm
  • Eject and remove SD card from PC and insert in EVM

Step 3b : Copy executable files to SD card (QNX+RTOS mode)

Note
make sure you have already prepared the sd card and copied the test data as mentioned in Run vision apps on EVM in QNX+RTOS mode (via SD card boot)
  • Insert the SD card onto your host PC SD card slot, (if not already inserted).
  • Do below to copy vision apps binaries to SD card
    cd ${PSDKR_PATH}/sdk_builder
    make qnx_fs_install_sd
    Note
    This loads the release versions of all the files
    OR
    cd ${PSDKR_PATH}/sdk_builder
    make qnx_fs_install_sd PROFILE=debug
    Note
    This loads the debug versions of all the files in case you want to use CCS to debug the programs
  • Eject and remove SD card from PC and insert in EVM

Step 4a: Run on EVM (Linux+RTOS mode)

  • To run the updated binaries on EVM , you can follow the steps mentioned in Step 4: Run on EVM

Step 4b: Run on EVM (QNX+RTOS mode)

  • To run the updated binaries on EVM , you can follow the steps mentioned in Step 4: Run on EVM
