File_SetPartition()

Syntax

File_SetPartition(bPartNum As Byte), Byte

Parameters

bPartNum — partition number to set as working partition (1-based)

Return value — cErrOK

            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.
