CC2340R2: Firmware size for CC2340R2 is not coming under 256KB after porting a project from CC2340R5 to CC2340R2

Hi lvan,

Thanks for the quick response.

I have used that Porting and Migration Guide, and followed every steps mention there.

Firmware is working fine as per my features, But still hex file after build is 512KB.

Please help me with this. Why is this generating 512kb of firmware after porting from CC2340R5 to CC2340R2?  How can I get the actual size of firmware?

Hi Aman, 

Please follow the following guide on checking the system flash and RAM usage with the Map file.

H Ivan,

I'm able to see the actual firmware size by the Map file.

Please help me with, How can I get the actual hex size generated after build. Is there any section I need to remove or modification on the alignment.

Please specify what steps I need to take to get the actual hex size after build.

Here I'm adding the screenshots of my .Map file, hex file generated after build, and post build steps being taken to generate hex.

Thank you.

Hi Aman,

Thanks for the screenshot. 

So you need to also update the update the .cmd file linked file in the project on CCS. You need to update the following: 

• Flash size
• Ram size
• FREERTOS
• Heapsize
• Application size
