This manual explains how to install Debian buster on the internal SSD drive of the “Utilite Pro” device, made by CompuLab<\/a>. Archived version of the official Utilite website is visible on Archive.org<\/a>. Wheezy installation for Utilite is described here<\/a>.<\/p>\n\n\n\n

First step is to download Debian armhf CD image, then partition the micro-SD card, upgrade U-boot to newer release, boot with new U-Boot and netinstall Debian buster. Followed by writing\/burning the updated U-Boot to internal SPI flash of the Utilite device (carefull with this step), and eventually U-Booting Debian over console from internal SSD drive.<\/p>\n\n\n\n

Shell environment to use # for root shell, and $ for user shell. Drive used here is mentioned as \/dev\/sdb, but can be anything else on your setup \/dev\/sdX.<\/p>\n\n\n\n

Serial console connection
First get serial connection working to be able to connect to Utilite\/U-boot console.<\/p>\n\n\n\n

screen \/dev\/ttyUSB0 115200
Device name can also be \/dev\/ttyS0<\/p>\n\n\n\n

Download Debian armhf ISO image
You can download Debian armhf ISO image from Debian cdimage depository. The downloadaded filename used in this installation was debian-10.3.0-armhf-netinst.iso.<\/p>\n\n\n\n

Starting
Install required Debian packages. Git clone the U-boot depository and compile cm-fx6 firmware image. Place it on micro-SD card.<\/p>\n\n\n\n

apt install -y build-essential gcc-arm-linux-gnueabihf bison flex bc git<\/h1>\n\n\n\n

$ git clone https:\/\/gitlab.denx.de\/u-boot\/u-boot.git
$ cd u-boot
$ git checkout v2020.01
$ export ARCH=arm
$ export CROSS_COMPILE=arm-linux-gnueabihf-
$ make cm_fx6_defconfig
$ make
$ tools\/mkimage -n spl\/u-boot-spl.cfgout -T imximage -e 0x908000 -d spl\/u-boot-spl.bin spl.img<\/p>\n\n\n\n

dd if=\/dev\/zero of=cm-fx6-firmware bs=64K count=1<\/h1>\n\n\n\n

dd if=spl.img of=cm-fx6-firmware bs=1K seek=1 conv=notrunc<\/h1>\n\n\n\n

dd if=u-boot.img of=cm-fx6-firmware bs=1K seek=64 conv=notrunc<\/h1>\n\n\n\n

Placing U-Boot firmware file on the micro-SD card<\/p>\n\n\n\n

dd if=cm-fx6-firmware of=\/dev\/sdb bs=1K seek=1 skip=1
Create partitions on the micro-SD card
Create a fresh filesystem on first partition. U-Boot will reside between the first partition and the MBR<\/p>\n\n\n\n

sfdisk -X dos \/dev\/sdb << ‘EOF’<\/h1>\n\n\n\n

2048 – – –
EOF
Create partition on micro-SD card<\/p>\n\n\n\n

fdisk \/dev\/sdb<\/h1>\n\n\n\n

p<\/h1>\n\n\n\n

n<\/h1>\n\n\n\n

1<\/h1>\n\n\n\n

2048<\/h1>\n\n\n\n

Choose default until the end of sectors. Choose Linux as partition type.<\/p>\n\n\n\n

w<\/h1>\n\n\n\n

Create an ext2 filesystem on the first partition.<\/p>\n\n\n\n

mkfs.ext2 \/dev\/sdb1<\/h1>\n\n\n\n

Copy the content of armhf CD ISO to the micro-SD card partition 1<\/p>\n\n\n\n

mkdir \/mnt\/armhfcdiso<\/h1>\n\n\n\n

mkdir \/mnt\/sdcard1<\/h1>\n\n\n\n

mount -o loop \/path_to_debian-10.3.0-armhf-netinst.iso \/mnt\/armhfcdiso<\/h1>\n\n\n\n

mount \/dev\/sdb1 \/mnt\/sdcard1<\/h1>\n\n\n\n

cp -rv \/mnt\/armhfcdiso\/* \/mnt\/sdcard1\/<\/h1>\n\n\n\n

sync<\/h1>\n\n\n\n

umount \/mnt\/sdcard1<\/h1>\n\n\n\n

umount \/mnt\/armhfcdiso<\/h1>\n\n\n\n

Debian U-Boot, kernel netboot
Netboot initrd kernel image. Plug in the ethernet cable into one of the Utilite ethernet’s ports, to continue with the installation.<\/p>\n\n\n\n

load mmc 2:1 0x12000000 install.ahf\/vmlinuz<\/h1>\n\n\n\n

load mmc 2:1 0x13000000 install.ahf\/netboot\/initrd.gz<\/h1>\n\n\n\n

load mmc 2:1 0x18000000 install.ahf\/device-tree\/imx6q-utilite-pro.dtb<\/h1>\n\n\n\n

setenv bootargs console=ttymxc3,115200 ${video}<\/h1>\n\n\n\n

bootz 0x12000000 0x13000000:0x164707d 0x18000000<\/h1>\n\n\n\n

Continue with the Debian installer, after successfull boot. These steps aren’t described. When the installer finishes, reboot and test boot SSD drive.<\/p>\n\n\n\n

Testing SSD drive boot<\/p>\n\n\n\n

sata init<\/h1>\n\n\n\n

load sata 0:1 0x12000000 vmlinuz<\/h1>\n\n\n\n

load sata 0:1 0x13000000 initrd.img<\/h1>\n\n\n\n

bootz 0x12000000 0x13000000:0x139535e 0x18000000<\/h1>\n\n\n\n

Writing new U-boot version on the internal SPI flash
Be carefull here, this can result into a bricked SPI flash (bricked Utilite) !!! This step is not obligatory, because you can always U-boot with micro-SD card<\/p>\n\n\n\n

load mmc 2:1 0x12000000 cm-fx6-firmware<\/h1>\n\n\n\n

sata init<\/h1>\n\n\n\n

load sata 0:1 0x12000000 vmlinuz<\/h1>\n\n\n\n

load sata 0:1 0x13000000 initrd.img<\/h1>\n\n\n\n

bootz 0x12000000 0x13000000:0x139535e 0x18000000<\/h1>\n\n\n\n

Possible Errors
There is a repeated dmesg USB error message, repeated every 2 seconds. I don’t know how to fix or ignore that. It’s not affecting the functionality of the device.<\/p>\n\n\n\n
