LPC55S16 2nd stage bootloader with Secure Boot

[evgreen]

Hello,

I am looking for a Secure Boot 2nd stage bootloader for LPC55S16.

On the LPC55S1x NXP web page, is listed the AN12327 application note for the implementation of a 2nd stage bootloader, but this bootloader doesn't include flashing Secure Boot firmware, only flashing a plain firmware received by UART.

Is possible to have such a 2nd stage bootloader with Secure Boot on LPC55S16? if so, can you please point me to some example or explain how to implement it?

Hello @evgreen 

Sorry there isn't second bootloader with secure boot so far. 

If you want to use secure boot, recommend enable secure boot function to use the secure bootloader inside BOOT ROM.
