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.
Thank you. I follow the answer and I think I successfully load secure boot loader. Then, I load application. But how can I trigger to start my application even I program with J-tag (not DFU). I used to use "nrfjprog --memwr 0x03fc00 --val 0x1" But it doesnt work.
