Hello,
I have already read the AN4758 application note and I still have a few questions regarding PCROP.
I have a project for end-users where the main application provides functions (API) that users can call to develop their own code. I was originally planning to provide these functions as a static library, but since PCROP is very useful and secure, I would prefer to protect my API using PCROP instead of distributing a library with unnecessary header files.
In my application, the region 0x08000000 to 0x0805DFFF contains my API code. I plan to flash this code first and then protect this area with PCROP.
Here are my questions:
If the end-user creates an empty project and I only provide the header files, can they still debug their own application even though the API code region is PCROP-protected?
Since a PCROP-protected area cannot be read or written, is there any way to update my API code later? I have a CAN bootloader, but this region will be protected by PCROP.
(I am using STM32G474RET6 with custom board.)
Thanks for your help,
BK
