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.
