Getting Started
1.Powering the Device: Hawkboard can be powered through USB OTG port(mini USB) or Separate 5V Source. Since the USB port of a PC/laptop or hub are often limited to 500 mA, it is advisable to use a separate power supply of 5VDC that supplies at least 1.5 A of current.  Note: It is recommended to use a separate 5VDC Power supply with at least a 1.5 Amps current rating instead of USB Power for Normal Operation of the Board

2.Connecting VGA Monitor: Once the power supply has been attached, Hawkboard boots to Uboot Bootloader and will show Hawkboard Logo on Screen.

3.Connecting UART: To transfer images to Hawkboard and to set other parameters, the UART/serial cable needs to be attached to Hawkboard and PC. A NULL Modem(Crossed Cable i.e 2 and 3 Crossed) is needed for that. Run a terminal session (such as Minicom on Linux or TeraTerm on Windows) on the Host PC and configure it to connect to that serial port with the following characteristics:
 * Bits per Second: 115200
 * Data Bits: 8
 * Parity: None
 * Stop Bits: 1
 * Flow Control: None
 * Transmit delay: 0 msec/char, 10 msec/line



After powering the device you should be able to see the following:


 * On Hyperterminal (Any other Serial Console) (Left) On VGA Monitor you will see HawkBoard Logo (Right)

Building & Booting Uboot images from source
HawkBoard comes with pre-installed U-boot and normally you don't want to Compile and Load U-boot unless you have Bricked the Bootloader or want to change something.So You can Skip this Section and can go Directly to Compiling Linux Kernel or Booting Kernel Section.

Compiling u-boot (bootloader)
host$ make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- distclean host$ make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- omapl_hawkboard_config host$ make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi-
 * 1) Issue compile commands with make:

Signing u-boot for UART boot

 * 1) Copy u-boot (elf) file to the host machine where AIS Generator is installed. Follow the below steps
 * 2) [[File:AIS gen uart1.JPG]]
 * 3) [[File:AIS gen uart2.JPG]]
 * 4) [[File:AIS gen uart3.JPG]]
 * 5) [[File:AIS gen uart4.JPG]]

Signing u-boot for NAND boot

 * 1) Copy u-boot (elf) file to the host machine where AIS Generator is installed. Follow the below steps

Compiling Linux Kernel
make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- distclean make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- omapl138_hawkboard_defconfig make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- uImage
 * 1) Issue compile commands with make:

Booting Linux Kernel and Mounting RAMDISK
You should find a kernel and a ramdisk image if you haven't found already. You can download samples from (uImage_v1 & ramdisk_v1.gz)). Then copy these files to your "/tftpboot" directory assuming you will use tftp for transferring files to your board. In order to do so you need to run a tftp server on your system. Under linux a good choice is atfptd, but you can also use others. Typically a linux tftp server exports the directory /tftpboot. Make sure before you continue that your ftp server is running. At the u-boot prompt:

Set ethernet connection:

$setenv serverip  $setenv ipaddr

 should be the address of the PC running the tftp server. should be an address that is not in use on the same subnet as the tftp server. Transfer files to the board:

$tftp c0700000 uImage_v1 $tftp c1180000 ramdisk_v1.gz

If you broke your bootargs previously then:

$setenv bootargs "mem=128M console=ttyS2,115200n8 root=/dev/ram0 rw initrd=0xc1180000,4M"

And finally boot the images:

$bootm c0700000

Booting Linux Kernel and Mounting NFS (Network File System)
Load the Kernel through NAND Flash or TFTP Method ,Once kernel has been loaded to RAM using tftp c0700000 uImage_v1 or similar Next. Follow following steps to Mount RootFS through NFS.(Ubuntu)

Setting NFS Server
1. Install NFS Server host$ sudo apt-get install portmap nfs-kernel-server

2. Share the Folder containing extracted RootFS (e.g /nfsroot contains RootFS)

Edit /etc/exports and add the shares:

/nfsroot (rw,sync,no_subtree_check,no_root_squash)

e.g, /nfsroot 192.168.0.0/255.255.255.0(rw,sync,no_subtree_check,no_root_squash)

Assuming your network is is 192.168.0.0

NB:- no_root_squash might be necessary if you are getting sudo erros in Ubuntu Rootfs

3.After setting up /etc/exports, export the shares:

host$ sudo exportfs -ra

restart the nfs-server if required host$ sudo /etc/init.d/nfs-kernel-server restart

Booting Board using NFS
Under Uboot prompt once the Kernel has been loaded through hawkboard.org> tftp c0700000 uImage_v1

1.Set bootargs Set boot arguments:

a)If Board uses Static IP

hawkboard.org> setenv bootargs 'console=ttyS2,115200n8 noinitrd rw ip=::: ::eth0: root=/dev/nfs nfsroot=:/nfsroot'

e.g  hawkboard.org> setenv bootargs 'console=ttyS2,115200n8 noinitrd rw ip=192.168.0.125:192.168.0.1:192.168.0.1:255.255.255.0::eth0: root=/dev/nfs nfsroot=:/nfsroot'

where 192.168.0.125 is board IP & 192.168.0.1 is gateway IP& Router IP.

b)DHCP IP Board hawkboard.org> setenv bootargs "mem=128M console=ttyS2,115200n8 root=/dev/nfs nfsroot=:/nfsroot ip=dhcp"

2.And finally boot the image:

hawkboard.org> bootm c0700000

Booting Linux Kernel from USB
This steps work for USB Pendrive connected to Hub or Directly to USB Standard Port and rootfs is Ubuntu jaunty made through rootstock.Should work for other distribution too.

1. Load uimage through tftp ( as usual) setenv serverip  setenv ipaddr  tftp c0700000 uImage_v1

2.Sent environment variable setenv bootargs console=ttyS2,115200n8 noinitrd root=/dev/sda1 rootwait rw init=/sbin/init

3.bootm bootm c0700000

Here /dev/sda1 is USB Drive with only one ext2 partition and rootfs lying init.

Booting Linux Kernel from SATA
Currently the provided u-boot does not allow booting from either SATA. However, it is possible to boot from nand and have the root filesystem loaded from SATA. If you want to do so, you have to figure out the right partition for the root filesystem and add that to your bootargs.

E.g. in u-boot say something like:

setenv bootargs mem=128M console=ttyS2,115200n8 root=/dev/sda1 rootwait

Where you replace /dev/sda1 with the name of the device that contains your root filesystem. /dev/sda1 is a good name for sata partition 1 if no usb or sd devices are present. Note that the rootwait argument is needed. It tells the kernel to wait until the disk has settled.

Booting Linux Kernel from SD OR MMC
Currently the provided u-boot does not allow direct booting from either SD or MMC However, it is possible to boot from nand and have the root filesystem loaded from SD If you want to do so, you have to figure out the right partition for the root filesystem and add that to your bootargs.

E.g. in u-boot say something like:

setenv bootargs console=ttyS2,115200n8 console=tty1 noinitrd root=/dev/mmcblk0p1 rootwait rw

or

setenv bootargs console=ttyS2,115200n8 console=tty1 noinitrd root=/dev/mmcblk0p1 rootdelay = 2 rootfstype = ext2 rw

Here p1 in mmcblk0p1 says that Rootfs is present in first partition of SD Card.

MISC
1.If you find screen broken, do this before bootm in u-boot, ideally this should go into kernel code

mw.l 0x01c14110 0x44442222 1;mw.l 0x01c14114 0x44400000 1;mw.l 0x01c14118 0x04604404 1;

2.For booting android over MMC the bootargs should be

setenv bootargs mem=128M console=ttyS2,115200n8 noinitrd root=/dev/mmcblk0p1 rootwait ip=off init=/init androidboot.console=ttyS2

3.You probably want to avoid that you have to retype these commands every time you want to boot. This can be achieved easily by issuing the following commands on the u-boot prompt:

setenv serverip  setenv ipaddr setenv bootargs_nfs mem=128M console=ttyS2,115200n8 root=/dev/nfs nfsroot=:/nfsroot ip=dhcp setenv bootcmd 'setenv bootargs $bootargs_nfs;tftp c0700000 uImage.v1; bootm c0700000' saveenv

Make sure to use single quotes in the last setenv command.
