I am using nrf51822, 16K RAM, 256K Flash.
From the movie, there is no way to secure my firmware for DFU. Is there any other way to secure my firmware?
Thank you
it is possible to compile the Secure Bootloader for a nRF51822 xxAA variant with only 16KB RAM, you have to alter the RAM settings, please see this answer.
The bootloader settings format of the Secure Bootloader is not identical to the format used by the legacy bootloader(SDK v11.0.0 and older). You have to generate the bootloader settings hex file using nrfutil and then merge this with the bootloader hex, this is explained in Appendix 1 in this Secure DFU blog.
