[edit] Flash SD
The OMAP processor follows a 2 stage boot process. Details on the boot procedure can be found at the boot sequence page.
SD flashing seems to be the fastest way to load files into the zoom2. However, a SD card must be formatted with the correct partitions prior to flashing any device. Once the SD is configured it will contain two separate partitions that will be used to boot the device. The FAT32 partition is used for uboot, xloader, and kernel. The ext3 partitions is used for the actual file system. Once both of these are loaded onto an SD the device can boot up and run the selected file system.
[edit] SD Configuration
Refer to SD Configuration process for a complete walk though on creating and testing a SD card. Once a SD card is prepared uboot, xloader, and kernel can then be loaded on the SD correct partitions.
[edit] Loading Bootloader, Kernel and Filesystem
Loading Uboot
- Refer to Omap Bootloader Project for more information regarding uboot and xloader.
Copying uboot onto SD boot partition:
# sudo cp -rf/tmp/mmc1
Loading Xloader
- Refer to Omap Bootloader Project for more information regarding uboot and xloader.
Copying xloader (MLO) onto SD boot partition:
# sudo cp -rf/tmp/mmc1
Loading Kernel
- Refer to Linux Omap Kernel for more information regarding Linux omap project.
# sudo cp -rf/tmp/mmc1
Loading Filesystem Select a file system to build. (Android, Linux, Poky, Angstrom, Busybox, etc...)
Copying filesystem onto SD disk partition:
# sudo cp -rf/tmp/mmc2
[edit] Flash NAND
[edit] Setup
u-boot and xloader images should be built prior to flashing to NAND. Refer to Omap Omap Bootloader Project for instructions on building uboot and xloader images.
[edit] Flashing u-boot and xloader to nand for first time
First, you will need to get the u-boot image into memory card using steps explained above.
Switch settings: Make sure the switch settings are set according to below table to boot from memory card:
MMC Boot Switch settings
| Switch | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 |
| S10 | ON | OFF | OFF | ON | ON | ON | ON | ON |
| S9 | ON | ON | ON | OFF | OFF | OFF | OFF | OFF |
| S8 | ON | ON | OFF | ON | ON | ON | ON | OFF |
| S6 | ON | ON | ON | OFF | ON | ON | ON | OFF |
| S4 | OFF | OFF | OFF | OFF | OFF | OFF | ON | ON |
| S14 | OFF | ON | ON | ON | ON | ON | ON | ON |
With above switch settings, insert the memory card with preloaded x-loader and u-boot images and boot the board. Run the following commands to flash boot loader into NAND flash.
mmcinit 0
[edit] u-boot flashing
fatload mmc 0 80008000 u-boot.bin nand ecc hw nand erase 80000 40000 nand write.i 80008000 80000 40000
[edit] X-loader flashing
fatload mmc 0 80008000 MLO nand ecc hw nand erase 0 40000 nand write.i 80008000 0 40000
[edit] uImage flashing
fatload mmc 0 90000000 uImage
nand ecc hw
nand write.i 90000000 0x280000 ${filesize}
[edit] FileSystem flashing
nand erase 0x780000 0x0A000000
tftp 90000000 poky.jffs2
OR ===> fatload mmc 0 90000000 poky.jffs2
nand write.i 0x90000000 0x780000 ${filesize}
After successful write operation, change the switch settings according to below table to boot from NAND
NAND Boot Switch settings
| Switch | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 |
| S10 | ON | OFF | OFF | ON | ON | ON | ON | ON |
| S9 | OFF | OFF | ON | OFF | OFF | OFF | OFF | OFF |

[edit] Updating u-boot and xloader to nand
Fetching u-boot via tftp
You will need to have a tftp server on the network and a host running a tftp server with the file u-boot.bin.
setenv serverip 128.247.78.27 tftpboot 80008000 u-boot.bin
Flashing u-boot into the Nand (be careful with the number of zeros)
nand ecc hw nand unlock 80000 80000 nand erase 80000 80000 nand write 80008000 80000 80000
Fetching x-loader via dhcp You will need to have a tftp server on the network and a host running a tftp server with the file MLO
setenv serverip 128.247.78.27 dhcp 80c00000 MLO
Flashing x-loader into the Nand (Note: need to use hw ecc for this)
nand ecc hw nand unlock 0 80000 nand erase 0 80000 nand write 80c00000 0 20000
[edit] Flash TFTP Kernel and NFS
[edit] SETUP TFTP ON LINUX PC
# sudo apt-get install xinetd tftpd tftp # sudo gedit /etc/xinetd.d/tftp
Add the following, save and exit
service tftp
{
protocol = udp
port = 69
socket_type = dgram
wait = yes
user = nobody
server = /usr/sbin/in.tftpd
server_args = -s /home/user/tftpboot
disable = no
}
- Create directory
# sudo mkdir /home/user/tftpboot # sudo chmod -R 777 /home/user/tftpboot # sudo chown -R nobody /home/user/tftpboot # sudo /etc/init.d/xinetd stop # sudo /etc/init.d/xinetd start
- Copy files
# cd /home/user/tftpboot # cp /home/user/l25.7/mydroid/bootloader/x-loader/MLO . # cp /home/user/l25.7/mydroid/bootloader/u-boot/u-boot.bin . # cp /home/user/l25.7/mydroid/kernel/arch/arm/boot/uImage . // use ifconfig to determine ip address - and use this for bootargs and serverip # ifconfig
[edit] SETUP NFS
# sudo aptitude -P install nfs-kernel-server nfs-common portmap //Specifically choose "No Loopback" to enable listening on other IPs # sudo dpkg-reconfigure portmap # cd /etc # gedit exports //add this line /home/user/l25.7/myfs *(rw,sync,no_subtree_check,no_root_squash) //make changes effective # sudo exportfs -a # sudo /etc/init.d/nfs-kernel-server restart WRITE XLOADER AND UBOOT TO NAND // UBOOT and MLO (xloader) should be in tftpboot directory // setup to configure bootargs - like in tutorial #1
- The below steps are completed within a Terminal
