I have a project working on the NUCLEO-N657X0-Q with FSBL and an application. In total I am using under 1MB of the 64MB flash this board has. I was wondering if it was possible to segment off the rest of the flash to be used as a mass storage device over USBX with FileX. I am using the load and run config instead of XIP.
The current flash usage is as follows:
- 0x70000000 - FSBL (66KB)
- 0x70100000 - Application (100KB)
- 0x71000000 - Weights and activations (400KB)
I know I can use cube programmer to write external data directly to the memory mapped flash drive but I would prefer to use standard file access tools. I have successfully implemented mass storage on a STM32H5 but that MCU didn't need to also load firmware so FileX could manage the whole drive as if it was empty.
Alternatively would it be possible to instead use FileX to load the FSBL/Application parts instead of the external memory manager?
