This page contains the instructions to create a Recovery USB device for the SBC-3.5-PX30 (D23) SECO board.
USB drive with at least 8GB available.
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.
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.gz and <image_name>.wic.bmap. For example:
seco-image-edgehog-seco-px30-d23.wic.gz seco-image-edgehog-seco-px30-d23.wic.bmap |
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.
