I'm working on developing a secure boot prototype for our product using Zephyr. Currently, I'm trying to decide between using the nRF52 MCU and the STM32 MCUs. It seems to me that the STM32 is a better option, as I can lock the first-stage bootloader using write protection, ensuring that it's immutable. On the other hand, I don't think the nRF52 offers this feature, as it's possible to erase all the Flash memory, including the bootloader. Could you please let me know if my understanding is correct?
Thank you so much for your help!
