Thanks for the clarification, now I understand.

In that case, placing the persistent data in the app_data area and the non-persistent data below the app_data region in Bank 1 is the way to go.

Hi Bjorn

Thanks for the response. Sorry you did not see the point of my question because perhaps I didn't make my intention more clear. I do store data in the APP data area that we need to preserve forever across DFUs. However we also have data that can be uploaded and thrown away before each DFU (user's intention to OTA DFU presumably provides the network engagement opportunity). We need as much "upload and throw away" space as possible, preferably outside of the persistent app data budget.

Hi Chang,

if the DFU_APP_DATA_RESERVED definition in the bootloader is set to 0, then the application data stored in the app_data section will be erased during DFU. So I do not really see the point of storing application data outside the app_data space.

Best regards

Bjørn
