Thanks

But this is not what I'm looking for.

I want to get access to external flash (SPI interface) using File System Emulation as its done with part of internal flash (Single-LUN example in USB library) .

i.e. I want to plug my USB stick in USB port in PC and just see saved data on external flash as file and perform on this file standard operations like copy/move/delete...

Yuri:

You may want to explore the MSC examples under USB to see if one of those comes close to what you want.

Simply change the code so that it does not access internal flash memory blocks but rather external storage memory blocks.
It doesn’t matter what data is on flash. The host device simply requests ‘flash data block #0, #1, ....’ and interprets it as file system data or file data itself. All the MSP does is mapping ‘data block #0’ to a memory location - either from its own flash space or from an external flash memory block.
Just replace the ‘fetch data block’ and ‘store data block’ functions by external flash access instead of internal one.
I’m sure there is such a hook and the data read/write operation is not inlined.
