Prepare installation media
Installation of generic Ubuntu 10.04 Server
- Connect the host PC to the CM-A510 via the serial cable supplied with the CM-A510 evaluation kit.
- Start terminal emulation software on your PC using the COM port to which the serial cable is connected. Set baud rate to 115200 bps, 8 bit per frame, 1 stop bit, no parity, no flow control.
- Connect LAN0 Ethernet port on CM-A510 (connector P11 on SB-A510) to your local Ethernet.
- Connect LiveUSB to L11 USB port on CM-A510 (connector P11 on SB-A510).
- Connect storage media to the SATA port (connector P18 on SB-A510).
- Turn on the CM-A510. The U-Boot boot-loader will start and you will get a command prompt.
|
If the boot settings of your CM-A510 are different than default, you may need to press and hold ^C while turning on the CM-A510, in order to get command prompt.
|
- Start the U-Boot USB subsystem, check that your LiveUSB has valid filesystem and boot.
usb start
fatls usb 0
fatload usb 0:1 0x00200000 /cdrom/uImage
fatload usb 0:1 0x01100000 /cdrom/uInitrd
setenv bootargs pm_disable console=ttyS0,115200 file=/cdrom/preseed/ubuntu-server.seed cdrom-detect/try-usb=true
bootm 0x00200000 0x01100000
- The resulting output should be similar to the following:

- Continue standard Ubuntu Server installation - choose timezone, partitions, username, password etc.
- Choose language, country, territory or area and keyboard layout
- Say "Yes" when asked "Continue the install without loading kernel modules?"
- Choose primary network interface, timezone and hostname
- Choose manual partitioning method.
- Make separate partition for /boot with ext2 or ext3 filesystem. It is essential because U-Boot is able to read uImage file only from the root directory of a partition.
- Make separate partitions for / and swap.
- For example use the following scheme:
SCSI1 (0,0,0) (sda) - 160.0 GB ATA Hitachi HTS54321
> #1 primary 100.0 MB F ext2 /boot
> #2 primary 158.9 GB F ext4 /
> #3 primary 1.0 GB F swap swap
|
|
If your partitioning scheme is different, you may need to edit U-Boot boot parameters accordingly.
|
- Write changes to disk and continue installing the system.
- Say "Yes" when asked "Continue without installing a kernel?"
- Choose username, password and wait until installation will be finished.
- Reboot the CM-A510, leave LiveUSB plugged in the USB port.
- The U-Boot boot-loader will start and you will get a command prompt.
- After the reboot
usb start
fatload usb 0:1 0x00200000 /cdrom/uImage
setenv bootargs 'root=/dev/sda2 pm_disable console=ttyS0,115200'
bootm 0x00200000
