Hello,

In SDK12.3.0\examples\dfu\bootloader_secure\pca10028\...

You will find the bootloader for nRF51. If you look at the function nrf_dfu_find_cache() in nrf_dfu_utils.c, you will see that the second parameter, bool dual_bank_only, will decide whether it should only accept dual banking.

By default, it will always try to do dual banking, but if there is not enough space, it will do single banking, if "dual_bank_only" is not true when you call nrf_dfu_find_cache.

 

Best regards,

Also, if you have not tried the bootloader yet, here is a great blog post to get started.
