An A133 firmware release typically contains:

| File | Description | |------|-------------| | boot0_sdcard.fex | First-stage bootloader for SD card | | boot0_nand.fex | First-stage for NAND/eMMC | | u-boot.fex | U-Boot binary | | boot_package.fex | Packed boot resources (DTB, logo, etc.) | | system.fex | Android system image | | vendor.fex | Vendor-specific binaries and libs | | config.fex | Board configuration (sys_config) |

Note: Allwinner uses .fex format – a text-based configuration that compiles to binary .bin via fex2bin.

Once your basic firmware works, the real "A133 firmware work" shifts to optimization and security. allwinner+a133+firmware+work
