Dear Hercules-team,
If have got the following questions from my customer:
Is the “Mirrored Flash” available for application use cases?
[Matthias]:
I don’t think so. If I understand the TRM and datasheet correctly, the “Mirrored Flash” (starting at 0x20000000) is just used for the ECC mechanisms and of course does include the same content than the main flash (starting at 0x00000000). It is physically the same memory. So it cannot be used for any firmware update mechanisms.
Also, similarly, what are the options for this part to have a small bootloader code installed such that it cannot be easily erased?
[Matthias]:
I know, we do have bootloader examples for different interfaces and they have to be executed starting from 0x00000000. Do we have in the Hercules MCUs any mechanisms to protect certain flash sections (like for a bootloader) to be accidently erased?
I have not found anything in the documentation.
Thanks, BR,
Matthias
