If the device no longer boots, FEL mode may be your only recovery option. Try the following:

| Component | Current Status | | :--- | :--- | | | Support for A133 SoC has been added, including DRAM initialization code. Available in patch series for mainline integration. | | Linux Kernel | Basic support exists via the A100 device tree (sun50i-a100.dtsi). Peripheral drivers are under active development. | | TF-A | Playground repositories provide minimal secure world firmware for experimentation. | | sunxi-tools | FEL tool support for A133 requires modifications (soc_info.c) to add device parameters. |

: The A53 architecture can get hotter at higher frequencies (up to 1.8GHz in "Plus" versions) compared to newer 22nm chips, which can lead to thermal throttling if the firmware's power management isn't finely tuned. Allwinner A133 Firmware
