The Image can be simply written to the SD Card by using the dd shell command in Linux:
$ cd <path to your image> $ sudo dd if=tq-image-weston-tqmarzg2n_b-mbarzg2x-<build Timestamp>.rootfs.wic of=/dev/sdc bs=1M conv=fsync #Assuming the SD card is assigned to /dev/sdc
To identify the SD card in Linux the shell command dmesg can be used:
$ dmesg | tail -n 15
$ dmesg | tail -n 15 #plug in SD Card into the reader $ dmesg | tail -n 15
A good approach to update the firmare components U-Boot,Linux kernel and devicetree in a running system it to load them from a tftp server.
This process requires a running TFTP server, please see the following page how to setup TFTP Server.
After setting up the TFTP server, the binaries to be updated must be copied into the TFTP directory.
1. Setup the Starterkit to boot from eMMC or SD
2. Connect the kit to the network with TFTP server supplying the binaries via ethernet on connector ETH0 (X26)
3. Power up the system and interrupt the boot process in U-Boot
Hit any key to stop autoboot: 0 =>
3. Setup the ethernet interface:
Set network settings using DHCP
4. Set U-Boot variable mmcdev according to the drive you want to write to.
=> setenv mmcdev <device_number>
5. Set the file name of the binary to update in U-Boot :
6. Perform Update by running the update command:
SD Card
=> run update_uboot_sd
=> run update_fdt_sd
=> run update_kernel_sd
eMMC
=> run update_uboot_mmc
=> run update_fdt_mmc
=> run update_kernel_mmc
