In embedded systems — especially those using ARM-based processors like MediaTek, Rockchip, or Allwinner SoCs — the is the very first piece of code that runs after the boot ROM. Its job is to initialize essential hardware (like DRAM clocks and controllers) and then load the next-stage bootloader (such as U-Boot).
: This could indicate the version of the microcontroller or the specific model within the K65 series. It might also refer to the voltage and/or the package type of the microcontroller. preloader-k65v1-32-bsp-2g-ago.bin
: This is the first-stage bootloader that initializes the hardware (like DRAM) and prepares the device to load the main operating system or firmware. In embedded systems — especially those using ARM-based
