Hello,
We have an application where we want to update the LPC55S69 over RF. The LPC55S receives new firmware fragments and stores them in Flash. This microcontroller has trustzone enabled with secure boot. The received image is signed with ROT and gets stored in encrypted flash region. Is the secondary bootloader able to check the new firmware signature and how can it handle the secure and non secure firmware. Is this all even possible?
