The xAF library contains base classes that can be used to implement file/flash I/O on any platform. These classes are:
- IOBase – This is the base class. Any other I/O class inherits from this class.
- FlashInterface – This class inherits the IOBase It is the base class that other classes will inherit from to implement flash access from a given platform.
- FileInterface – This class inherits the IOBase It is the base class that other classes will inherit from to implement file access from a given platform.
You can find the header files for these classes in the xAF repo at public/include/ folder. Examples are provided for IVP and Summit.
IVP
On IVP, the Win32 I/O files are in:
- FlashInterfaceWin32
- FileInterfaceWin32
You can find the source files in the xAF repo at: private/utils/xAFVirtualAmp/interface.
Summit
On Summit, you can find a reference implementation of these files on the Summit repo, on the xaf_examples branch, under customer/reference/xaf_reference_app/interface:
- FileInterfaceSummit
- FlashInterfaceSummit Note: This would be implemented to open a file right now instead of accessing
flash memory.
For example, this is how to use the FlashInterfaceSummit to read data:
FlashInterfaceSummit* flashTest = (FlashInterfaceSummit*)summitFlashInterface.getInstanceOf(); flashTest->open(0, IOBase::access_read);
