MicroSD Boot Memory
MicroSD Boot Memory Connections
● Refer to all requirements and recommendations for Minimal Connections
● When the Propeller 2 starts up (or is reset) with this circuit, it will automatically boot from firmware saved
on the microSD card. If microSD boot fails, a further serial window of 60 seconds will be followed by
shutdown.
● The microSD card must be formatted as FAT32, and the boot firmware file must be saved in the root of
the microSD card with the special filename: _P2_BOOT.BIX
● Each Propeller 2 firmware image requires up to 512 KB. A single microSD card could hold multiple
firmware images or code snippets, and/or be used for user data. The microSD card is fully available to the
user program as a general memory area.
