If *image_addr* is not specified, the bootelf command will try to find image in *image_load_addr* variable (*CONFIG\_SYS\_LOAD\_ADDR* by default). Args after *image_addr* will be passed to application in common *argc*, *argv* format. A command sequence to run a ELF image using FDT might look like :: load mmc 0:1 ${loadaddr} /kernel.elf load mmc 0:1 ${fdt_addr_r} /soc-board.dtb bootelf -d ${fdt_addr_r} ${loadaddr} ${loadaddr} image_addr Address of the ELF binary. fdt_addr Address of the device-tree. This argument in only needed if bootable application uses FDT that requires additional setup (like /memory node). arg Any text arguments for bootable application. This is usually the address of the device-tree. Flags: -p Load ELF image via program headers. -s Load ELF image via section headers. -d Setup FDT by address. Configuration ------------- The bootelf command is only available if CONFIG_CMD_ELF=y. FDT setup by flag -d need CONFIG_CMD_ELF_FDT_SETUP=y. |
