Introduction

This article provides an installation guide for Linux kernel and Debian root file system on the UCM-iMX7 System-on-Module / Computer-on-Module eMMC internal storage device.

Preparation steps

  • Obtain a PC workstation with a USB port.
  • Download the Linux package for UCM-iMX7 from CompuLab website. Unzip the package to a directory on your host workstation.
  • All image files mentioned below can be found in the install subdirectory.
  • Use the standard microUSB-to-USB cable to connect the host PC to the micro USB connector P7 on SBC-UCM-iMX7).
  • Make sure the new /dev/ttyUSBx device file is created by using the ls /dev/ttyUSB* command. x is the last number of the ttyUSB device.

Preparing installation media

  • Obtain a micro SD card. Any commercially available micro SD card of 1GB (or larger) may be used.
  • Create a first partition on it. The partition can be formatted either ext2/3/4 or FAT file system.
  • For installation on eMMC copy all files found in the directory install from the unzipped Linux package to the first partition on the installation media (micro SD card).
  • For installation on NAND flash following files from the package directory install to the installation SD card:
    • boot.scr
    • install.ext2
    • kernel.img
    • ramdisk.img
    • rootfs.tar.bz2
    • zImage
    • imx7d-sbc-ucm-imx7.dtb

Automatic Installation Procedure

  • Start terminal emulation software on your PC with the following serial port settings:
Baud Rate Data Bits Stop Bits Parity Flow Control
115200 8 1 none none
  • Plug the installation media (SD/microSD card) into the SD socket:
    • On SBC-iMX7 - SD socket P9
    • On SBC-IOT-iMX7 - micro-SD socket P18
    • On IOT-GATE-iMX7 - socket marked uSD
  • Turn on the system.
  • The system will boot from the SD card and start the automatic installation procedure.
        Kernel release : Linux 4.14.98-cl-som-imx7-6.3

===CompuLab Automatic Installation System 2.0.1 (Nov 20 2018)===
Press any key to cancel installation   0

The Automatic Installation Procedure can be terminated by pressing any key during the timeout.

  • The installation script performs all necessary steps including installing Linux images onto the on-board storage device (eMMC) and setting up the boot environment.
Admolition note.png The Automatic Installation script deletes the storage device during the installation procedure. All data stored on the eMMC will be lost. 
=== Installation Target: eMMC ===
* Mounting extra images
* Loading extra modules
===Installing OS===
* Updating partitions
* Formatting partitions
* Copying kernel files
* Extracting user space rootfs.tar.bz2

* Unmounting extra images
Please remove installation SD card ...
Press any key to cancel restart   0

  • The system will reboot automatically to the newly installed Linux. Please reboot manually, if for some reason the system does not reboot automatically.
  • Please remember to remove the installation SD card.

Troubleshooting

  • Automatic installation doesn't start.

The U-Boot environment should be set to default:

  • Power on the board.
  • Press and hold Ctrl-C to get command prompt.
  • Set default U-Boot environment and boot the board:
UCM-iMX7 # env default -a
UCM-iMX7 # saveenv
UCM-iMX7 # reset
