iasimage

iasimage is a utility program for creating Intel Automotive Service (IAS) images, a binary file format understood by bootloaders to load and initialize Operating Systems or Hypervisors.

iasimage supports the following features:

  • Create an image (including kernel cmdline, kernel, hypervisor binary etc.)
  • Attach a signature to an IAS image
  • Extract components from an IAS image

Examples

Create an IAS image

iasimage create -o iasImage -i 0x30000 cmdline.txt bzImage initrd

Create a multi-file IAS image of type #3 with default page alignment:

iasimage create -o iasImage -i 0x30000 cmdline.txt bzImage initrd acpi Firmware1.bin --page-aligned

Create a multi-file IAS image of type #3 given page alignment:

iasimage create -i 0x40000 cmdLine.txt elf1.bin cmdLine2.txt elf2.bin -o test_image.img --page-aligned=2

Default page alignment values for multi-file images are:

  • for type #3 alignment is 5
  • for type #4 alignment is 4
  • for type #10 alignment is 2

Sign an IAS image

iasimage sign -o iasImage_signed -s rsa.sig -k pub_key.pem iasImage

Create a signed IAS image with a private key (for development purposes only).

iasimage create -o iasImage -i 0x30300 -d priv_key.pem cmdline.txt bzImage initrd

Extract components from an IAS image

iasimage extract iasImage
