RETAINING FLASH MEMORY AFTER DFU PROCESS

[arshdeep]

Hi Team Nordic,

I am trying to save my flash data after the DFU process but it keeps on erasing it. I saw a thread in which it was explained to increase the CODE_PAGE_SIZE in order to save the flash data. 

I did increase it:

#ifndef DFU_APP_DATA_RESERVED
#define DFU_APP_DATA_RESERVED (CODE_PAGE_SIZE * 254)
#endif

But still, the data that I am storing at address 0XB2000 and 0XB3000 is getting erased. 

Am I missing something here? Please suggest !!

Thanks,

Arshdeep

Hi,

As you can see in the code , it says no bootloader start address is configured.

Do I have to make some changes here?

Thanks,

Hi,

If I am not mistaken the bootloader start address in UICR gets written together with the bootloader, from the bootloader hex file. Have you successfully programmed the DFU bootloader to the device?
