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
