Partition table and filesystem size
|
||||||
|
-----------------------------------
|
||||||
|
|
||||||
|
ESP32 firmware contains a bootloader, partition table and main application
|
||||||
|
firmware, which are all stored in (external) SPI flash. The user filesystem
|
||||||
|
is also stored in the same SPI flash. By default, MicroPython does not have
|
||||||
|
a fixed entry in the ESP32 partition table for the filesystem. Instead it
|
||||||
|
will automatically determine the size of the SPI flash upon boot, and then --
|
||||||
|
so long as there is no existing partition called "vfs" or "ffat" -- it will
|
||||||
|
create a partition for the filesystem called "vfs" which takes all of the
|
||||||
|
remaining flash between the end of the last defined partition up until the
|
||||||
|
end of flash.
|
||||||
|
|
||||||
|
This means that firmware built for, say, a 4MiB flash will work on any
|
||||||
|
device that has at least 4MiB flash. The user "vfs" filesystem will then
|
||||||
|
take up as much space as possible.
|
||||||
|
|
||||||
|
This auto-detection behaviour can be overridden: if the ESP32 partition
|
||||||
|
table does contain an entry called "vfs" or "ffat" then these are used for
|
||||||
|
the user filesystem and no automatic "vfs" partition is added. This is
|
||||||
|
useful in cases where only the MicroPython ESP32 application is flashed to
|
||||||
|
the device (and not the bootloader or partition table), eg when deploying
|
||||||
|
.uf2 files.
