Hi all,

Does u-boot support loading custom binary executables?

I know u-boot supports standalone applications and operating systems.

The scenario is like this.

1. u-boot completes the hardware booting.
2. It loads the custom binary image(elf file) from flash to SDRAM and pass over the control to that binary.

The custom binary is built using code warrior tool(an IDE) and it deals with hardware components which are not touched by u-boot(It does not reinitialize things done by u-boot and doesn't need a console).

ie. the custom binary application does not use any functions provided by u-boot, it just want an environment to execute itself.

Is this possible?

yes, if it's just a booting a elf use bootelf
