nrf_dfu_app_is_valid equivalent in SDK 15.3

[Hrishi]

Hello,

I am trying to upgrade my working projects to SDK15.3 from SDK15.2. All projects work except the bootloader project as there are significant differences in 15.3. Is there a migration document I can refer to for this?

My present issue is about finding a replacement for nrf_dfu_app_is_valid() in SDK15.3. Can you please help?

Thank you,

Hrishi

Hi Hrishi, 

The equivalent to nrf_dfu_app_is_valid in SDK v15.3 is app_is_valid() function. And the CRC check is inside boot_validate(). 

Note that there is some changes in the bootloader SDK v15.3 regarding the bootloader start address. Please have a look here.
