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
