Concerns secondary bootloader DA14580

Hi all,

I was wondering if the secondary bootloader hex file, generated in training 06 (SUOTA), is only
needed once for the python script to generate the spi_multipart.bin file and the other 2
image files. In other words: Is it sufficient to only copy newly generated .img files to
my mobile phone to update the BLE firmware without programming the spi_multipart.bin file every time?
Any help I will appreciate.

Hi BlueSDK18,

I am not sure if i get what exactly you mean, the secondary bootloader is part of the multipart.bin file (the entire multipart file contains the two .img files and the secondary bootloader along with the product header and the image headers). On your phone you should copy the .img file that you would like your device to be updated with, just the image with its header (the output of the mkimage single command). The SUOTA procedure will just update in the flash one of the allready existing images, the other image and the bootloader and the product header will stay intact.

Thanks MT_dialog
