By default, if you power up your board it will run the software on the flash. But you can prepare a MicroSD card and boot from it by inserting it to the MicroSD card reader of your IGEP Processor Board, as it has more priority than the flash.

If you have a brand new IGEP Processor Board you must know that it comes with a firmware provided and installed on it by ISEE.

Therefore, when you power up your board it boots the pre-installed software, which consists on a minimal Linux-based distribution with a lite X Window System and GNOME Mobile based applications created with Poky Platform Builder.

If you want to update your pre-installed software, you can create a MicroSD card in your host PC with the latest sofwtare. Then boot your IGEP Processor Board from that MicroSD card.

Finally, you can write the updated software from the MicroSD to the flash memory on your IGEP device.

This How-To is meant to be a starting point for people to learn to:

• create a SD card with latest firmware available
• write it to the flash memory

for any IGEP Processor Board as quickly and easily as possible.

Note: this How-To was tested with an Ubuntu 10.04 host machine, but most of the contents are valid also for other GNU/Linux distributions. We do not issue any guarantee that this will work on other distributions.

How to create a SD-card with latest software image

The first thing you'll do is download latest firwmare

wget http://downloads.igep.es/binaries/firmware/poky-firmware-3.3.1-10.tar.gz

Next, untar the firmware and enter to the directory

tar xzf poky-firmware-3.3.1-10.tar.gz
cd poky-firmware-3.3.1-10/

Insert your SD card into the host machine (the machine you downloaded the firmware), and run following command

./poky-media-create --mmc [device] --binary poky-image-sato-igep00x0-[timestamp].tar.gz --machine [machine]

where:

• [device] is the SD card device name, for example: /dev/sdb
• [machine] is the machine name, options are
  • igep0020
  • igep0030
  • igep0032

Finally plug the SD card into IGEP device and power up your board.

How to flash the latest software image

Now you have a booted board with latest firmware running from SD card, you can write the firmware to the flash memory.

Enter to the IGEP device using root as login name and an empty password, enter to the /opt/firmware an run the ./flash script

cd /opt/firmware
./flash.sh

When finish, unplug the SD card and reboot the board, enjoy the new firmware running from flash memory.
