Preloader-k62v1-64-bsp.bin 'link' -

You have a device stuck with no display, no USB detection, or "dead boot." Using a hardware flasher like (for MTK) or RKDevTool (if Rockchip variant, but here it's MTK style), you need to load this preloader first. In SP Flash Tool, this file is loaded into the "RAM test" or "Download Agent" section before the main flash.

The file is part of a Board Support Package (BSP) specifically designed for the hardware platform. In the MediaTek ecosystem, the "preloader" is the very first piece of code executed from the eMMC or UFS storage when the device powers on. Its main responsibilities include: Preloader-k62v1-64-bsp.bin

The in the filename indicates the processor architecture—specifically, ARM64 (AArch64) . This means the bootloader is compiled to run in 64-bit mode, allowing the device to utilize more RAM and run 64-bit operating systems efficiently. This distinguishes it from older 32-bit legacy bootloaders. You have a device stuck with no display,

The preloader-k62v1-64-bsp.bin from Device A has GPIO pins configured for SDIO1. If flashed to Device B, the inline "storage detection loop" will poll SPI2, see no response, and trigger a hard watchdog reset infinitely. This results in a "boot loop" before any screen turns on.
