# 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

* Create your work directory `mkdir generated.arm; cd generated.arm`
* Build an ARM toolchain using `../configure --build-cross-tools arm ../../buildtools`
2013-04-28 22:01:28 +04:00
* Build our loader using `jam -q -sHAIKU_BOOT_BOARD=beagleboneblk haiku_loader`
* TODO
# Booting
1. If the boot switch is not depressed:
MMC1, MMC0, UART0, USB0
2. If the boot switch is depressed:
SPI0, MMC0, USB0, UART0
