Download firmware and prepare the ConnectCore 6 SBC
Get the necessary firmware for the ConnectCore 6 SBC.
- Download any firmware images (Android or Yocto) from http://www.digi.com/support.
- Extract the firmware image files from the zip file you downloaded, either to:
- Your TFTP server's exposed folder (typically /tftpboot) if you plan to update via Ethernet TFTP.
- A FAT formatted microSD card if you plan to update via microSD card on the board.
- Change the boot source configuration to boot from the internal eMMC:
- Set the boot source jumpers: J4: open, J5: open.
- Boot the device and immediately press a key in the serial terminal to stop the autoboot process. You will be stopped at the U-boot boot loader prompt (shown below):

=> - Upgrade the U-Boot boot loader either:
- From TFTP (assuming the file is on the TFTP server's exposed folder):
=> update uboot tftp <u-boot-file.imx>
- From a FAT formatted microSD card, where you previously copied the file:
=> update uboot mmc 1 fat <u-boot-file.imx>
- From TFTP (assuming the file is on the TFTP server's exposed folder):
- Reset the board to boot into the just updated U-Boot, and press any key to stop the autoboot process.
- Reset the U-Boot environment to default values (this will not reset protected variables like the MAC addresses):
- Follow the appropriate instructions to update the eMMC firmware:
=> env default -a => saveenv
