META-IOT2050

This Isar layer contains recipes, configuration and other artifacts that are specific to Debian-based IOT2050 product.

Build example image

Before building the system, you will need to install docker on build host. For example under Debian Linux

sudo apt install docker.io

Then build the example image

./kas-container build kas-iot2050-example.yml

Build the example RT image, for example

./kas-container build kas-iot2050-example.yml:kas/opt/preempt-rt.yml

Using 3rd-party mirrors, for example

./kas-container build kas-iot2050-example.yml:kas/opt/mirror-example.yml

After build complete, the final image is under

build/tmp/deploy/images/iot2050/iot2050-image-example-iot2050-debian-iot2050.wic.img

Build user SDK

Note: Current SDK only supports Linux x86-64 host machine

./kas-container build kas-iot2050-example.yml:kas/opt/sdk.yml

After build complete, the SDK tarball is located at

build/tmp/deploy/images/iot2050/sdk-isar-arm64.tar.xz

Please follow the further instruction file README.sdk under the SDK tarball

Clean build result

./kas-container --isar clean

Build released version

First checkout the desired tag. Then build the image or sdk by appending the kas/opt/package-lock.yml:

# example image
./kas-container build kas-iot2050-example.yml:kas/opt/package-lock.yml

# example rt image
./kas-container build kas-iot2050-example.yml:kas/opt/preempt-rt.yml:kas/opt/package-lock.yml

# bootloader for advanced board
./kas-container build kas-iot2050-boot-advanced.yml:kas/opt/package-lock.yml

# bootloader for basic board
./kas-container build kas-iot2050-boot-basic.yml:kas/opt/package-lock.yml

# SDK
./kas-container build kas-iot2050-example.yml:kas/opt/sdk.yml:kas/opt/package-lock.yml

Booting the Image from SD card

Under Linux, insert an unused SD card. Assuming the SD card takes device /dev/mmcblk0, use dd to copy the image to it. For example:

$ sudo dd if=build/tmp/deploy/images/iot2050/iot2050-image-example-iot2050-debian-iot2050.wic.img \
          of=/dev/mmcblk0 bs=4M oflag=sync

Alternatively, install the bmap-tools package and run the following command which is generally faster and safer:

$ sudo bmaptool copy build/tmp/deploy/images/iot2050/iot2050-image-example-iot2050-debian-iot2050.wic.img /dev/mmcblk0

The example image starts with the IP 192.168.200.1 preconfigured on the first Ethernet interface, and use DHCP at another. You can use ssh to connect to the system.

The BSP image does not configure the network. If you want to ssh into the system, you can use the root terminal via UART to ifconfig the IP address and use that to ssh in.

NOTE: To login, the default username and password is root. And you are required to change the default password when first login.

Selecting a boot device

By default, the boot loader will pick the first bootable device. If that device may no longer fully start, you can select an alternative boot device in the U-Boot shell. Attach a USB-UART adapter to X14, connect it to a host PC and open a terminal program on that port. Reset the device and interrupt the boot when it counts down ("Hit any key to stop autoboot"). Then type

=> setenv boot_targets mmc0
=> run distro_bootcmd

to boot from the microSD card. Use usb0 for the first USB mass storage device.

NOTE: This selection is not persistent. The boot loader will fall back to its default boot order after reset.
