It was discovered that attempting to load x86-64 format ELF files with a multiboot1 header using the qemu `-kernel` command would result in an error, as multiboot1 only allows x86-32 format ELF files. To address this limitation, we have developed a simple x86_32 bootloader. This bootloader is designed to copy the `nuttx.bin` file to the designated memory address (`0x100000`) and then transfer control to NuttX by executing a jump instruction (`jmp 0x100000`).
