Create SD Card with BSP Image
To install a new firmware use SD cards. To copy the built images on the host system to a connected card type:
$ cd <BSP project>/platform-<platform_name>/images
$ sudo dd if=u-boot_@mod_name_code@_hd.img of=/dev/sdf bs=1M conv=fsync #Assuming the SD card is assigned to /dev/sdf
You have to use the raw device of the SD card not a partition!
To find out what device file the SD card has, type “dmesg” after you connect the card to see the system messages.
At the bottom you'll see some “Attached scsi …” messages along with something like:
[ 8197.588395] sdf: sdf1
Updating existing firmware over ethernet
To update bootloader / kernel / devicetree in a running system you have to copy the images in your tftp directory and download them to the eMMC or SD Card.
Please see How to setup TFTP Server
1. Boot from eMMC or SD and stop autoboot
2. Set U-Boot variable mmcdev according to the drive you want to write to (mmcdev 0 = eMMC, mmcdev 1 = SD card)
3. Connect device via ethernet to a tftp server supplying the image
4. Provide the correct network configuration:
setenv autoload no
setenv serverip <serverip> (e.g.: setenv serverip 192.168.100.110)
setenv ipaddr <ipaddr> (e.g.: setenv ipaddr 192.168.100.111)
setenv netmask <netmask> (e.g.: setenv netmask 255.255.255.0)
5.Provide U-Boot the file name of the desired image on the server:
For U-Boot:setenv uboot <filename>
For device tree:setenv fdt_file <filename>
For Kernel:setenv kernel <filename>
6.Perform Update:
For U-Boot: run update_uboot
For devicetree: run update_fdt
For Kernel: run update_kernel

Prepare development host for TFTP download
TFTP Server and copy the NOR Flash image into the TFTP folder.
Boot SD and stop autoboot
Connect device via ethernet to a tftp server supplying the image
Provide the correct network configuration:
setenv autoload no
setenv serverip <serverip> (e.g.: setenv serverip 192.168.100.110)
setenv ipaddr <ipaddr> (e.g.: setenv ipaddr 192.168.100.111)
setenv netmask <netmask> (e.g.: setenv netmask 255.255.255.0)
Download the image from tftp server to $loadaddr with the following command:
tftp $loadaddr <filename>
example
tftp $loadaddr core-image-minimal-tqmt1042-64b-stk-20170126034615.rootfs.nor
Make all NOR Flash banks writable with and erase the whole NOR Flash with:
protect off all
erase all
Write image from $loadaddr onto the NOR Flash:
cp.b $loadaddr 0xE8000000 8000000
