Flash memory usage for Application Data

We are currently using RSL10 for our application development.
For the application I am required to store 65KB of data.

From the “RSL10 Firmware Over-The-Air User’s Guide” Section 3.1
“The Bluetooth Low Energy stack, which contains the Device Firmware Update (DFU) component and the padding between the sub-images, allocates about 154KB. The remainder of the RSL10 main flash memory is available for the application (380KB - 154KB - 8KB approximately equal to 218KB).”

Is this true in case of RTOS built image also?

Thanks & Regards,


Please confirm these questions.

  1. Will this 65KB data save to RAM or need save to Flash?
  2. If it is in RAM, it might be able to use DSP_DRAM.
    If it is in Flash and it needs use FOTA, the calculation (380KB - 154KB - 8KB =218KB
    This is true. If it needs 65KB for store data, then only (218-65) KB for application.

You have asked similar question at " Flash writing to NVR and Flash Areas error".
We have provided reference code in there.
