CC1350 Launchpad
project 0

Congratulations on choosing the CC1350 Wireless MCU and LaunchPad ecosystem! This example will show you how to build/compile your own images for use with the BLE OAD service using Code Composer Studio.

Before starting on this tutorial you need to download and install Code Composer Studio 6.1.3 or later.
We will use the rfWsnDmNode example in CCS as a basis for this tutorial. Basically any of the examples in the TI-RTOS CC13xx/CC26xx SDK can be used to build a OAD capable image, but since the rfWsnNode and Concentrator examples already contain code for getting back to BLE stack mode (i.e. double button press for 10s) we will for the sake of simplicity use this as a starting point.
To get started follow these steps:
1
Import rfWsnDmNode from the Resource Explorer in Code Composer Studio.
2
In project option -> ARM Compiler -> Advanced Options -> predefined symbols add 'USE_BIM' define
3
In project option -> ARM Hex Utility -> check Enable ARM Hex Utility
4
In CC1350_LAUNCHXL.cmd move the application start address to page 2 + 10B BIM header:

5
Open rfDmExamples.cfg, click the ‘cfg script’tabe to edit the file directly and not use the GUI editor.
a. Comment out the ROM config at line 367 so that TIRTOS is not in ROM. This is because the ROM’ed TIRTOS assumes TIRTOS const data is in the same location as the BIM header.


b. Move the reset vector at line 202 to be above page 0 and the BIM header:

6
Build the project to generate the intel hex file
7
Convert the .hex to the format required by the iOS OAD app

a. Clone or copy the OAD conversion script at ti-simplelink Github

b. install python

c. install crcmod:

  • Download from python.org
  • Extract the files
  • Cd into the dir and run 'python setup-py install'

d. install intelhex:

  • Download from python.org
  • Extract the files
  • Cd into the dir and run 'python setup-py install'
8
Run the script to convert the file
python ~/[path_to_script]]/oad_image_tool.py rfWsnDmConcentrator_CC1350_LAUNCHXL_TI_CC1350F128.hex -ob rfWsnDmConcentrator_CC1350_LAUNCHXL_TI_CC1350F128_oad.bin -m 0x1000 -r :0xE000
9
Send the resulting _oad.bin file to an email account that you can access from you iOS device.
10
Open the SensorTag app on the iOS device, if the CC1350LP is running the BLE FW give it a reset and you should see it in the list of devices, click on the CC135LP and open the sensor view.
11
Open the e-mail on the iOS device, _oad.bin click the attachment and open with the SensorTag App
12
When it switches back to the SensorTag App select FW Download then select the file that was in the e-mail which should now be in the list of available firmwares.
13
The App built at the start should be downloaded to the LP, once downloaded the CC1350LP will reset and run your app! If the App does not start you may need to reset the device manually by pressing the reset button.
14
To get back to the BLE stack/app mode press and hold BTN-1 and BTN-2 for >5s until the green led blinks rapidly (note this requires the button logic from the one of the fWsnDm examples). If the BLE FW does not start you may need to reset the device manually.
