Setting up the Haiku SD card

The BeagleBone Black supports booting from an microSD card while the boot switch is pressed at power on. A MBR file system layout is normally used as seen below. Partition 1 is all that is required to boot an OS.

  • partition 1 -- FAT32, bootable flag, type 'c'
  • partition 2 -- BeFS, Haiku filesystem, type 'eb'

Boot Partition

Required files

  • MLO
  • u-boot.img: u-Boot image
  • uEnv.txt: u-Boot Environment settings

Optional files

  • ID.txt: Unknown

Compiling

  • Create your work directory mkdir generated.arm; cd generated.arm
  • Build an ARM toolchain using ../configure --build-cross-tools arm ../../buildtools
  • Build our loader using jam -q -sHAIKU_BOOT_BOARD=beagleboneblk haiku_loader
  • TODO
