Hello everyone, 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!
I don’t know the answer to this one, but as it relates specifically to the features of the Nordic nrf52 I would recommend opening a thread on the Nordic DevZone forums.
Hi @marko, @mike,
Thank you for creating this ticket as well as useful guidance. I’ve already created a thread on Nordic DevZone forums and have the answer here (in case you are interested).
Thank you and best regards,
Itachi.
