bootelf command

Synopsis

bootelf [-p|-s] [-d <fdt_addr>] [<image_addr> [<arg>]...]

Description

The bootelf command is used to launch a ELF binary at image_addr. 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.
