 +===== Updating existing firmware over ethernet =====
 +\\
 +To update bootloader / kernel / devicetree in a running system you have to copy the images to a tftp directory and upload them to the eMMC or SD Card.\\  
 +
 +
 +
 +Please see [[en:general_information:tftp|How to setup TFTP Server]]
 +
 +
 +**1. Boot Starterkit and interrupt boot process in U-Boot**\\
 +<code>Hit any key to stop autoboot:
 +=></code>
 +
 +**3. Connect device via ethernet to the TFTP server which supplies the image**\\
 +
 +**4. Provide the correct network configuration in U-Boot:** 
 +<WRAP round info>
 +The manual network configuration must be done if no DHCP server is available, otherwise the configuration can be done via DHCP. 
 +</WRAP>
 +
 +== Manual 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)
 +
 +== Network configuration via DHCP ==
 +
 +  * => setenv autoload no 
 +  * => dhcp
 +\\
 +**5. Set U-Boot environment variables according to the image file name stored on the tftp server:** 
 +
 +  * For U-Boot update on eMMC/SD Card : => setenv uboot_mmc <filename> (e.g.: setenv uboot_mmc u-boot-with-spl-pbl.bin)
 +  * For U-Boot update on QSPI NOR : => setenv uboot_qspi <filename> (e.g.: setenv uboot_qspi u-boot-pbl.bin.bswap )
 + 
 +  * For Device Tree update on eMMC/SD Card and QSPI NOR : => setenv fdt_file <filename> (e.g.: setenv fdt_file fsl-tqmls1043a-mbls10xxa.dtb)
 +  
 +  * For Kernel update on eMMC/SD Card and QSPI NOR : => setenv kernel <filename> (e.g.: setenv kernel linuximage)
 +
 +\\
 +**6. Perform Update: **
 +  
 +  * U-Boot update on eMMC /SD Card : => run update_uboot_mmc
 +  * U-Boot update on QSPI NOR : => run update_uboot_qspi
 +
 +  * Device Tree update on eMMC /SD Card : => run update_fdt_mmc
 +  * Device Tree update on QSPI NOR : => run update_fdt_qspi
 +
 +  * Kernel update on eMMC /SD Card : => run update_kernel_mmc
 +  * Kernel update on QSPI NOR : => run update_kernel_qspi
