Marko Kiiskila resolved MYNEWT-523.
-----------------------------------
Resolution: Fixed
Size is now more acceptable. Both for RSA and with ECDSA when using 256 bit
curve.
> boot - boot loader with BOOTUTIL_SIGN_RSA/EC is too large

> Key: MYNEWT-523
> URL: https://issues.apache.org/jira/browse/MYNEWT-523
> Project: Mynewt
> Issue Type: Bug
> Components: Bootloader
> Affects Versions: v1_0_0_beta1
> Reporter: Simon Ratner
> Assignee: Marko Kiiskila
>
> With image signatures enabled, boot loader weighs in at ~27kB, which is too
> big for both the nrf51 and nrf52. Even disabling most of mbedtls and only
> keeping minimum required features comes to 25kB(EC) / 20kB(RSA).
> Without signature support, boot loader is ~12kB.
> Maybe consider secp256r1 with tinycrypt as an option for smaller footprint?
