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.

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 CC2340R5 project into Code Composer Studio (CCS)

  2. Open SysConfig and click on the Show board view in the upper right

3. Click on Switch and then select the CC2340R53 Development Platform as the new value

  1. Click Confirm and Save.

5. After migration to CC2340R53 the .cmd file is updated; for BLE projects extra steps are required, please reference the BLE migration guide for detailed steps on the migration process.

6. Rebuild and run your project, in memory allocation view we should see that the SRAM is now re-sized to 64 kB.
