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.
Yes, if you want to use the Secure Bootloader, then you have to use SDK v12.2.0. The Secure bootloader for nRF51 in SDK v12.2.0 uses S130 v2.0.0, so as long as your application uses the same SoftDevice you should be OK.
