Can I code signing for DFU firmware?

[sosse]

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

Hi Sosse,

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.

Best regards
