 --------------------------------

 6. Update software on board:
 ----------------------------
-6.1. partitioning of binaries:
------------------------------
-TF-A build provide a binary named "tf-a-*.stm32" which MUST be copied on a
-dedicated partition named "fsbl1"
+Please use STM32CubeProgrammer then only tick the boot partitions means patitions 0x1 to 0x6 (more informations on the wiki website http://wiki.st.com/stm32mpu)
 
-6.2. Update via SDCARD:
------------------------
-Copy the binary (tf-a-*.stm32) on the dedicated partition, on SDCARD/USB disk
-the partition "fsbl1" are the partition 1:
- - SDCARD: /dev/mmcblkXp1 (where X is the instance number)
- - SDCARD via USB reader: /dev/sdX1 (where X is the instance number)
-    $ dd if=<tf-a binary> of=/dev/<device partition> bs=1M conv=fdatasync

-FAQ: to found the partition associated to a specific label, just plug the
-SDCARD/USB disk on your PC and call the following command:
-    $ ls -l /dev/disk/by-partlabel/

--------------------------------------------
-* Plug the SDCARD on Board.
-* Start the board and stop on U-boot shell:
- Hit any key to stop autoboot: 0

-* plug an USB cable between the PC and the board via USB OTG port.
-* On U-Boot shell, call the usb mass storage functionnality:
- STM32MP> ums 0 mmc 0
- ums <USB controller> <dev type: mmc|usb> <dev[:part]>
-  ex.:
-For SDCARD:      ums 0 mmc 0
-For USB disk:    ums 0 usb 0
