CC2640R2F: RAM/Flash not enough for BLE 5 features in CC2640R2F?

Choongbeom You

Part Number: CC2640R2F

Hello,

I've seen some threads about using ble5 stack in cc2640r2f, and there's a saying that ram and flash may not enough for using all BLE 5 features.

I want to check how much ram and flash can be used in my application.

Could you check below memory map information for app and stack each? (with IAR and TI-RTOS, including high speed and long range features and NPI)

1. Bytes of total ram and flash memory usage of the "simplelink_cc2640r2_sdk_4_20_00_04\examples\rtos\CC2640R2_LAUNCHXL\ble5stack\host_test"

2. Bytes of total ram and flash memory usage of the "simplelink_cc2640r2_sdk_4_20_00_04\examples\rtos\CC2640R2_LAUNCHXL\ble5stack\simple_peripheral"

Thanks,

Calvin

You can build those projects and check output MAP file to know RAM/Flash usage.

Hi Chen,

I'm sorry but I could not build the projects because of IAR version currently.

Could you help me if you can? It's ok If you have difficulty checking it.

Thanks,

Calvin

I don’t mind to build those projects. However, I won’t be able to access my desktop to build them in the next two days. If you are in a hurry, I would suggest you to build them by yourself. If you aren’t in a hurry, can wait.

Hi Chen,

Thank you for your help.

I can wait. We're upgrading IAR license but it takes some time.

Thanks,

Calvin
