What’s in the box?

  • CN9132 EVK (ClearFog CX CN931x)

  • 16GB Micro SD card (Optional)

  • Heatsink

  • Wall mount Power supply 12V@2.5A or 12V@5A (Optional)

Software Setup

Cable setup and prerequisites

Here is what you will need to power up the board:

  • Linux or Windows PC

  • CN9132 EVK (ClearFog CX CN931x )

  • DDR4 SO-DIMM Memory

  • 12V Power adapter

  • Micro USB to USB for console, the CN9132 EVK has an onboard FTDI chip.

  • IP router or IP switch

Please Note

For Application using CN9132 COM express with multiple M.2 modules, SATAs and PCIe add-in card , a power supply 12V@5A is required.
For Applications using CN9130 with few additional interfaces, a power supply of 12V@2.5A is sufficient.

The following is a list of industry-standard cables, sorted by type, with the necessary compliance requirements that have been proven to work well with the CN913x product family.

These examples are the cables which SolidRun uses for testing, and should provide enough information to source products from your preferred cable vendor.

  • Ethernet cable: Monoprice 24AWG Cat6A 500MHz STP

  • USB Cable: SuperSpeed USB 3.0 Type A Male to Female Extension Cable in Black

  • SFP connector: GigaLite GE-GB-P1RT-E SFP module with Monoprice 24AWG Cat6A 500MHz STP cable

Boot Select

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 CN913x COM Boot Select .

Booting from an SPI card

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

Switch 1

Switch 2

Switch 3

Switch 4

Switch 5

OFF

ON

ON

OFF

ON


The following shows how to set the switches on the boot source selector:

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

Please Note:

The SPI including U-Boot by default.

1. Downloading the Ubuntu 20.04 image

1 wget https://solid-run-images.sos-de-fra-1.exo.io/CN913x/cn9130-cex7_config_0_ubuntu-4cbe176.img.xz

2. Writing the image to the SD card

Use the following commands for writing the image to an SD card:

1 xz -dc cn9130-cex7_config_0_ubuntu-4cbe176.img.xz | dd of=/dev/sdX bs=4k conv=fdatasync

Note: Plug a micro SD into your Linux PC, the following assumes that the micro SD is added as /dev/sdX and all it’s partitions are unmounted.

3. SD card insertion

Please Insert the SD card into your device.

4. Power connection

Connect your power adapter to the DC jack, and then connect the adapter to mains supply.

5. Serial Connection

Please insert the micro USB into your device, then you can refer to Serial Connection for installing necessary serial connection software in Linux/Windows.

In u-boot prompt, to continue booting from SD card, run the following:

1 2 3 4 5 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

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).

Once you installed the necessary serial connection software and ran the above commands , you should be able to see the following:

  • In order to be able to log in , please insert “root” as a username and password as follows:

7. Final stages

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 :

SFP Modules

For some SFP modules that work on SolidRun networking hardware platforms, please refer to SFP Modules .

SIM Card Slot

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.

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.
