Compiling the firmware

Setup development environment

  1. Download and install SIMPLELINK-LOWPOWER-F2-SDK 7.41.00.17
  2. Download and install Code Composer Studio 12.6.0

Compiling

  1. Create a folder called workspace in the folder where the SDK is installed. In the SDK installation folder you should see files like Makefile and license_simplelink_cc13xx_cc26xx_sdk_7_41_00_17.txt.
  2. Start Code Composer Studio, it will ask you to select a workspace folder, select the workspace folder you created in the previous step.
  3. Go to File -> Import -> Code Composer Studio -> CCS Projects -> Select search-directory: simplelink_cc13xx_cc26xx_sdk_7_41_00_17/examples/rtos.
  4. Select:
    • znp_CC1352P_2_LAUNCHXL_tirtos7_ticlang
    • znp_CC26X2R1_LAUNCHXL_tirtos7_ticlang
    • znp_LP_CC1352P7_4_tirtos7_ticlang
    • znp_LP_CC2652R7_tirtos7_ticlang
    • znp_LP_CC2652RB_tirtos7_ticlang
  5. Press Finish.
  6. In Code Composer Studio, expand the 5 projects and for each open znp.syscfg, expand Power Management and change Minimal Poll Period (ms) to 1000, change it back to 100 immediately and save the file.
  7. Copy *.patch to the SDK installation folder, open a Git Bash in this folder and apply the patch using git apply *.patch --ignore-space-change.
  8. Build the 5 projects; right click -> Build project.
    • Important: by default the launchpad variant of the CC1352P2_CC2652P (= znp_CC1352P_2_LAUNCHXL_tirtos7_ticlang) is build. To build the other variant comment #define LAUNCHPAD_CONFIG 1 in preinclude.h (located under Stack/Config/), don't forget to save.
  9. Once finished, the firmware can be found under znp_*_tirtos7_ticlang/default/znp_*_tirtos7_ticlang.hex
    • znp_CC1352P_2_LAUNCHXL_tirtos7_ticlang.hex -> CC1352P-2 and CC2652P based boards
    • znp_CC26X2R1_LAUNCHXL_tirtos7_ticlang.hex -> CC2652R based boards
    • znp_LP_CC1352P7_4_tirtos7_ticlang.hex -> CC1352P7 based boards
    • znp_LP_CC2652R7_tirtos7_ticlang.hex -> CC2652R7 based boards
    • znp_LP_CC2652RB_tirtos7_ticlang.hex -> CC2652RB based boards

Binary maclib_*.a changes in firmware.patch

Note that the firmware.patch patches the binary maclib_*.a files. These changes are required to fix the coordinator crashing when the TX power is set to 5+. In SDK 7.10.02.23 TI made changes to macSetTxPowerVal which introduced this issue. The patch reverts these changes. The patched maclib_*.a files were provided by a TI employee and will only work for the 7.41.00.17 SDK.
