iPXE - compilation, configuration and including in firmware

NOTE: this procedure applies to legacy releases older than v4.0.14

Compilation

1. Prepare build environment, if you haven't done so yet
2. Build firmware, if you haven't done so yet

3. Clone iPXE repository:

   git clone git@github.com:pcengines/ipxe.git
   

4. Configure and run build in container:

   docker run -v ${PWD}/../src/coreboot:/coreboot -v ${PWD}/../src/ipxe:/ipxe -t -i pc-engines/apu2b
   cd /ipxe
   wget https://raw.githubusercontent.com/pcengines/apu2-documentation/master/ipxe/general.h -O src/config/local/general.h
   wget https://raw.githubusercontent.com/pcengines/apu2-documentation/master/ipxe/shell.ipxe -O src/shell.ipxe
   

   wget downloads iPXE configuration that maximize feature set that is exposed. Supported features:

   • net proto: IPV4, IPV6, STP
   • download proto: TFTP, HTTP, HTTPS, FTP, SLAM, NFS
   • image: NBI, ELF, MULTIBOOT, PXE, SCRIPT, BZIMAGE, COMBOOT, SDI, PNM, PNG

   For more details please check general.h.

   make bin/8086157b.rom EMBED=./shell.ipxe
   

   Note that ${PWD}/../src/ipxe is absolute path to repository cloned in point 3.

As a result you will have bin/8086157b.rom

Including in firmware image

To include iPXE ROM in coreboot.rom please use cbfstool.

To add iPXE ROM to existing image inside container:

cd /
./coreboot/build/cbfstool ./coreboot/build/coreboot.rom add -f /ipxe/src/bin/8086157b.rom -n genroms/pxe.rom -t raw

If you already have genroms/pxe.rom, please remove it and then add new version:

./coreboot/build/cbfstool ./coreboot/build/coreboot.rom remove -n genroms/pxe.rom
