Overview

This page contains the instructions to create a Recovery USB device for the SBC-3.5-PX30 (D23) SECO board.

Requirements

Hardware

• USB drive with at least 8GB available.

Software

• The two image files .wic and .wic.bmap

seco-usb-flash-image-seco-px30-d23.wic
seco-usb-flash-image-seco-px30-d23.wic.bmap

• bmaptool installed in an host PC.

Creation of USB recovery device

• Insert the USB drive in the host PC and use bmaptool command to create bootable USB device:

$ sudo bmaptool copy seco-usb-flash-image-seco-px30-d23.wic /dev/<your-device>

• In the USB device's image partition you can find the /INSTALL/ folder. Inside this folder you shall copy the image files you want to install on the board. The files needed in this step are <image_name>.wic.bz2 and <image_name>.wic.bmap. For example:

seco-image-edgehog-seco-px30-d23.wic.bz2
seco-image-edgehog-seco-px30-d23.wic.bmap

Installation phase

To install the new version on the board the steps are described as follow:

• Plug the Recovery USB device in a powered off board.

• Power on the board stopping in bootlader (CTRL+C command)

• In U-Boot run the following command in order to ensure that the USB device could be correctly read:

 > setenv bootusb true; setenv usb_pgood_delay 3000; saveenv; command 

• Run the command:

> boot

• Check if Booting from USB ... log appears in boot logs.

• Once the system has booted the copying procedure starts itself. It could be possible to check the progress running the command:

$ journalctl -u seco-install -f

• Once the procedure end succesfully, you can restart the board without the Recovery USB to boot with the updated software.
