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 firmware.patch to the SDK installation folder, open a Git Bash in this folder and apply the patch using git apply firmware.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.
