I'm using the STM32F405 microcontroller.
For my application/calculation I need to store temporary a lot of data, which exceed my SRAM.
To expand it, without using an external SRAM, I had following ideas:
- Use the Backup-SRAM as common SRAM (only 4kB).
Question: Is there a write limitation e.g. 100.000 write cycles?
- Store some data in the flash memory.
Question: How can I configurate the linker to keep e.g. the last 100kByte free?
Do I just need to reduce the parameter “__Main_Stack_Size” from 1024 to 924
