 ===== Deployment PTXdist =====
+==== 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:
+<code bash>
+$ cd <BSP project>/platform-<platform_name>/images
+$ sudo dd if=u-boot_<label mod_name_code>MOD_NAME_CODE</label>_hd.img of=/dev/sdf bs=1M conv=fsync #Assuming the SD card is assigned to /dev/sdf
+</code>
+<WRAP round tip>You have to use the raw device of the SD card not a partition!</WRAP>
+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:
+<code bash>
+[ 8197.588395]  sdf: sdf1
+</code>
+----
+==== 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 upload them to the eMMC or SD Card.\\
+Please see [[en:general_information:tftp|How to setup TFTP Server]]
+. Boot from eMMC or SD and stop autoboot in U-Boot\\
+<code>Hit any key to stop autoboot:  0
+=></code>\\
+. Set U-Boot variable //mmcdev//  according to the drive you want to write to
+<code>=> setenv mmcdev <Nr.></code>
+<WRAP round info 30%>__Device assignment:__\\
+//mmcdev 0// = eMMC\\
+//mmcdev 1// = SD Card\\
+</WRAP>
+. Connect device via ethernet to a tftp server supplying the image\\
+. Provide the correct network configuration in U-Boot:
+  * => 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)
+\\
+. Provide U-Boot the file name of the desired image on the tftp server:
+  * For U-Boot update: => setenv uboot <filename>\\
+  * For Device Tree update: => setenv fdt_file <filename>\\
+  * For Kernel update: => setenv zimage <filename>\\
+\\
+. Perform Update:
+  * U-Boot update: => run update_uboot\\
+  * Device Tree update: => run update_fdt\\
+  * Kernel update: => run update_kernel\\
+<WRAP round info>
+The u-boot update scripts automatically implement the selection of the primary copy to boot.
+</WRAP>
+\\
+----
+==== Copy Firmware from SD card to eMMC using U-Boot ====
+  * Write Image to SD card (use dd command under linux or Win32diskImager under Windows)
+  * Set Starterkit to boot from SD, please see [[en:arm:tqma6x:starterkit|DIP Switch Settings]]
+  * Interrupt the boot process to get to the U-Boot prompt
+  * Use the following command to copy the SD card to eMMMC
+=== Generic command ===
+<code>
+mmc dev 1 && mmc rescan && mmc read ${loadaddr} 0 (number of blocks)  && mmc dev 0 && mmc rescan && mmc write ${loadaddr} 0 (number of blocks)
+</code>
+<WRAP round important>
+You have to set the number of blocks according to the image size to read entire data that is stored on the SD card and write the same number of blocks to the eMMC.\\
+**Formula to calulate the number of blocks**\\
+Size of SD card image in bytes / 512. Convert the result to a hex value.\\
+Since the data is stored in the SDRAM on the module the size of the image must not exeed the size of the SDRAM.
+</WRAP>
+++++Example for precompiled SD card image included in BSP Rev.0109|
+   * Size of uboot_tqma6q_hd.img in byte = 276.824.064
+   * 276.824.064 / 512 = 540.672
+   * 540.672 converted to hex value = h840000
+<code>
+mmc dev 1 && mmc rescan && mmc read ${loadaddr} 0 0x84000  && mmc dev 0 && mmc rescan && mmc write ${loadaddr} 0 0x84000
+</code>
+++++
+\\
+==== Copy rootfs from SD card to eMMC ====
+The rootfs is located in the second partition of the SD card/eMMC  please see [[en:arm:tqma6x:linux:ptxdist:adapt_bsp#partition_scheme|Partition Scheme]]
+example for TQMa6Q
+<code bash>
+dd if=/dev/mmcblk0p2 of=/dev/mmcblk1p2 bs=1M
+</code>
+<WRAP round important 50%>
+please keep in mind to resize the eMMC rootfs partition,\\
+if the rootfs size was changed in BSP configuration
+</WRAP>
+==== Using NFS boot ====
+== Prerequisites ==
+  * [[en:nfs|How to setup the NFS Server on your Host Computer]]
+  * [[en:tftp|How to setup the TFTP Server on your Host Computer]]
+To boot the <label mod_name>MOD_NAME</label> from network you need a working bootloader in eMMC/SD-card or SPI-NOR (placement option on <label mod_name>MOD_NAME</label>) which is able to get the kernel image over tftp and to provide the kernel with commandline settings for NFS.\\
+The dtb-file and kernel image have to be provided via tftp and the rootfs via nfs.\\
+== Configuration of U-Boot Environment ==
+The bootloader environment needs to be modified to work with your tftp-server and your nfs-server.
+  * setenv autoload no
+  * setenv serverip <serverip> (e.g.: setenv serverip 192.168.100.1)
+  * setenv ipaddr <ipaddr> (e.g.: setenv ipaddr 192.168.0.10)
+  * setenv netmask <netmask> (e.g.: setenv netmask 255.255.255.0)
+  * setenv rootpath <rootpath> <wrap important>(NFS share has to set in /etc/exports on the Computer that runs the NFS server first)</wrap>
+  * setenv fdt_file <fdt_file> (name of devicetree file to be downloaded from the tftp server)
+  * setenv zimage <zimage> (name of the Linux kernel image to be downloaded from the tftp server)
+\\
+==== TQMa6x serial downloader ====
+<WRAP round important> You have to set the Starterkit to boot-mode "serial downloader", please see [[en:arm:tqma6x:mba6x:dip_switches|MBa6x DIP switch settings]]
+</WRAP>
+<WRAP round info>
+We recommend to use Ubuntu 14.04 64bit for the imx-usb tool
+</WRAP>
+Starting with TQMa6x-BSP-REV.0109 we deliver a Linux tool to upload U-Boot into the TQMa6X RAM from your development host and start it.
+After building the BSP the tool is located under \\
+**.../TQMa6x-BSP-REV.0109/platform-MBa6x/packages/h-imx_usb_loader-master**\\
+You have to apply the following steps before you can start to work with the tool:
+  * Copy the content of folder .../TQMa6x-BSP-REV.0109/platform-MBa6x/packages/host-imx_usb_loader-master/usr/etc/ to /etc
+  * Copy the content of folder .../TQMa6x-BSP-REV.0109/platform-MBa6x/packages/host-imx_usb_loader-master/usr/bin/ to /bin
+==== Usage of serial downloader tool ====
+  - Set Starterkit to boot-mode "serial downloader", please see [[en:arm:tqma6x:mba6x:dip_switches|MBa6x DIP switch settings]]
+  - Connect Starterkit connector X8 (Micro USB cable provided with the Starterkit) to your host
+  - Connect Starterkit connector X15 (RS232) to your host
+  - Power up Starterkit
+  - Please check that Linux recognized a new USB device, see output of command **dmesg | grep -i usb**. You should see something like the following :<code>usb 1-1: Manufacturer: Freescale SemiConductor Inc
