A production firmware image contains:

Firmware work extends beyond bootloaders into the Linux kernel's firmware subsystem. The A133 relies on binary blobs for certain co-processors.

The FEL mode, while primarily used for bootloader loading, can also be used for more advanced firmware operations. The sunxi-tools package provides the sunxi-fel utility, which implements various subcommands for interacting with FEL-capable Allwinner chips. This is hardcoded into the chip

For volume production environments, Allwinner provides a suite of tools including:
