XIAO SAMD21 Only Showing 48k of Flash Storage

Does anyone know why there is only 48K of flash storage available? This unit should have 256K.

XIAO SAMD21

I am running the latest CircuitPython (8.0.5) and bootloader (3.15).

The 48k is the space available for the file system. The total flash size of the chip is 256k, and most of it us used for the firmware, like CircuitPython ode MicroPython or the Arduino code you load to the device.

That makes sense. Thanks for the reply.
