axf file to SD Card

contra — Wed, 26 Jun 2013 17:39:37 GMT

Hi, I am creating a bare metal application for i.mx28 EVK using ARM-DS5. My project outputs a .axf file. How can I get this onto SD card so that I can boot it?

I don't need to use Linux or Windows CE as my application is very simple and requires boot speed.

If the AXF contains records in ELF format, you can use the tool "elftosb" to convert the ELF file into i.MX28 binary format .SB.

Usage

usage: elftosb [-?|--help] [-v|--version] [-f|--chip-family <family>]

[-c|--command <file>] [-o|--output <file>]

[-P|--product <version>] [-C|--component <version>]

[-k|--key <file>] [-z|--zero-key] [-D|--define <const>]

[-O|--option <option>] [-d|--debug] [-q|--quiet] [-V|--verbose]

[-p|--search-path <path>] files...

Options:

-?/--help Show this help

-v/--version Display tool version

-f/--chip-family <family> Select the chip family (default is 37xx)

-c/--command <file> Use this command file

-o/--output <file> Write output to this file

-p/--search-path <path> Add a search path used to find input files

-P/--product <version Set product version

-C/--component <version> Set component version

-k/--key <file> Add OTP key, enable encryption

-z/--zero-key Add default key of all zeroes

-D/--define <const>=<int> Define or override a constant value

-O/--option <name>=<value> Set or override a processing option

-d/--debug Enable debug output

-q/--quiet Output only warnings and errors

-V/--verbose Print extra detailed log information

After installing the i.MX28 LTIB, the "elftosb" can be found at the path "/opt/freescale/ltib/usr/bin". Please let me know if you need to run in Windows.

Example

Usually, we provide a command file to specify how to load and run the input ELF. The command file can be as simple as

File: uboot.bd

______________________________________________________________________

// STMP378x ROM command script to load and run U-Boot

sources {

u_boot="/ltib/rootfs/boot/u-boot.elf";

}

section (0) {

//----------------------------------------------------------

// Load and call u_boot - ELF ARM image

//----------------------------------------------------------

load u_boot;

call u_boot;

}

_______________________________________________________________________

and the command line to execute elftosb is

elftosb -z -f imx28 -c ./uboot.bd -o imx28_uboot.sb
