Free memory space available for user data in SPI Flash

Hello Dialog,

May I know the usable range of addresses in SPI Flash once its programmed to hold firmware.

Settings -

I am using BLE pillar example - sleepmode.

On awake from Sleep mode, I write to the Flash @ address - 0x24000

I will want to store at least 80 KB of data in SPI Flash.

Thanks

Raju

Hi rajucoolsuraj,

Hi rajucoolsuraj,

This depends on the size of your firmware! I would suggest you to burn the SPI flash with your firmware, and then read it from the flash programmer of SmartSnippets toolbox. With this way you can easily find in which addresses the firmware is stored. The empty addresses will have the value 0xFF.

Thanks, PM_DIalog

Thanks Dialog,

Thanks Dialog,

I will verify the usage based on the above recommended method.

1. I would like to know whether the flash is used for any other bluetooth specific purpose ?

2. Does the same method apply for dual image system for having SUOTA enabled firmware and flash configuration based on SUOTA scheme 1 (only Flash)?

Thanks

Hi rajucoolsuraj,

Hi rajucoolsuraj,

No, we don’t use the SPI flash for any other specific purpose. If you would like to have SUTA functionality, I would strongly recommend you to have a look at theTutorial 6: SUOTA example for DA14585/6tutorial. After burning the SPI Flash, again you can read it in order to check in which address the firmware is stored.

Thanks, PM_Dialog
