IV. Select Project→Options→Linker→Checksum to configure a CRC16 calculation over the
application image. Make sure that the start address does not include the CRC and CRC Shadow
locations and that the checksum ends at the last address of the specified image region of the
OAD Target. By default, then, the CRC covers the range 0x9004 through 0x12FFF. Make sure
that the Algorithm uses CRC16 with 0x1021. If this value is set to any other value than 0x1021, it
can be modified by setting the algorithm first to CRC polynomial, and then setting the Algorithm
back to CRC16.
V. Under Tools, include cc26xx_app_oad.icf and exclude cc26xx_app.icf. Also exclude
ccfg_app_ble.c. Add the OAD profile modules to the PROFILES folder of the workspace. These
files are located here: $BLE_INSTALL$/src/profiles/oad/cc26xx .
