Once you set the switches, you can apply the following for booting from an SPI card and loading the Ubuntu from an SD card.

Note

Please Note:

The SPI including U-Boot by default.

...

Code Block
setenv get_images "load mmc 1:1 $kernel_addr_r boot/Image; \
load mmc 1:1 $fdt_addr_r boot/cn9132-cex7.dtb; \
setenv root 'root=/dev/mmcblk1p1 rootwait rw'; setenv ramdisk_addr_r -"
saveenv
boot
Note

Please Note:

Boot is made from SPI by default, so in order to continue booting from an SD card, the above commands should be run only once (in the fist boot).

...

The following stages need to be done in order to finalise the imaging:

  1. Run fdisk /dev/mmcblk1 if using SD, or run if using fdisk /dev/mmcblk0 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/mmcblk1p1 if using SD Card, or Run resize2fs /dev/mmcblk0p1 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.

Please see below an example of resizing the filesystem :

...

It is possible to utilize a Cellular connection by inserting a SIM card into the SIM card slot. Please observe that a GSM Cellular modem needs to be installed utilizing the mini PCIe connection in order to exploit the cellular connection.

Note

Please Note

If you your ClearFog has dual SIM card slots, an additional cellular modem will need to be installed in the mini PCIe connection in order to utilize the 2nd SIM connection.
