CC2340R5 to CC2340R53 Porting Guide

This section will describe, in general terms, how to migrate a project developed for the CC2340R5 device to a CC2340R53 device running the SimpleLink Low Power F3 SDK. However, it is important to first assess the differences between both devices to make sure that the project migration is possible .. TODO

The primary difference between CC2340R5 and CC2340R53 is the SRAM size, as specified in their respective datasheets. CC2340R5 has 36 kB SRAM, and CC2340R53 has 64 kB SRAM.

Migration Guide

The recommended migration path is to start with a CC2340R5 based example project from the SimpleLink Low Power F3 SDK and follow the next steps:

  1. Import the project into Code Composer Studio or you IDE of preference.

  2. Open SysConfig, go to Device View and click on SWITCH.

  1. Once the Switch Board or Device window is opened, select the CC2340R53 board, or 64 kB device and click on CONFIRM. Make sure to save the project changes so that the migration takes place.

Warning

If a new linker command file is generated after migration (named cc23x0r53.cmd in the project files) please make sure to exclude it from build (or eliminated it from the project files) so that the original lpf3_app_freertos.cmd file is used during build time.

  1. Build and flash the project.
