For images after Aug 5, 2024, there is a really nice update of the Rescue Loader to version #200 for the above boxes, that allows either recovery to a different STARTUP slot or reflash and boot an image.
New in this version:
Selection of the startup partition.
Uploading an image from your PC and flashing it to one of the startup partitions.
Downloading an image online and flashing it to one of the startup partitions.
Displaying information such as MAC address and bootloader version.
To install:
Unzip the appropiate box (gbquad4k, gbue4k) file and copy the rescue.bin to /tmp on your box.
Then connect via Telnet and enter the following command:
Invocation:Code:dd if=/tmp/rescue.bin of=/dev/mmcblk0p3
Turn off the box using the power switch at the back.
Open the front flap.
Press and hold the "up" button.
Turn on the box using the power switch at the back.
Wait for the countdown on the display until the IP address of the box is shown
In a browser enter the IP address displayed on the Gigablue LCD
Then you can select a new STARTUP image and reboot or flash a different image using the displayed Menu.
