Before powering up the board for the first time it is recommended to select the boot media. In order to configure the boot media, please refer to LX2160A CeX7 Boot Select <TBD>.

Booting from an SD card

The switches on the boot source SW1 selector must be set as follows:

...

Code Block
load mmc 0:1 0xa4000000 ubuntu-core.img
mmc dev 1
mmc write 0xa4000000 0 0xd2000

...

Note

Please Note:

The above commands should be run only once (in the fist boot).

...

  1. Run fdisk /dev/mmcblk0 if using SD, or run if using fdisk /dev/mmcblk1 eMMC.

  2. Recreate the first partition by deleting it and then creating a new partition that starts at block 131072 and extends to the end of the drive (or less depending on your needs).

  3. Write the new partition, when prompt about ‘Do you want to remove the signature?’ then answer with yes.

  4. Run resize2fs /dev/mmcblk1p1mmcblk0p1 if using SD Card, or Run resize2fs /dev/mmcblk0p1mmcblk1p1 if using eMMC.

  5. In this stage the root partition should be big enough to start populating it; but first update the RTC clock.

  6. Connect the RJ45 to your network with internet access (and DHCP server); and then run dhclient .

  7. Update the RTC clock by running ntpdate pool.ntp.org and then hwclock -w.

  8. Run apt-update and then populate the root filesystem as you wish.
