bPartNum	partition number to set as working partition (1-based)
Return value	cErrOK

Overview

cErrInvalidFormat

cErrInvalidPath (bad number)

Switches the currently mounted (working) partition

Switches the currently mounted (working) partition. Partition number is 1-based, matching File_ListPartitions()'s enumeration order.

Call File_ListPartitions() first.

Note: Doesn't re-run the SD card power-up handshake, only the boot-sector parse, so it's cheap to call repeatedly.
Partition 1 is always set as default working partition at File_Init() time.

Example
