 The U-Boot bootloader is wrapped in a ATF FIP package placed at '0x0f00000 - 0x0ff00000' (960KiB at 15MiB offset) and is loaded/verified/executed by the ATF. You can update this taking the 'fip.img' created by the Newport BSP Makefile uboot target and using Linux {{{dd}}} or U-Boot {{{mmc-write}}}.
 
-For example:
+Examples:
+ * build u-boot and update the fip.img within the u-boot directory:
+{{{#!bash
+cd /usr/src/newport/bsp
+. ./setup_environment
+cd u-boot
+make -j8 distclean thunderx_81xx_defconfig u-boot-nodtb.bin && \
+ cp ../atf/build/t81/release/fip.bin fip.img && \
+ fiptool update --nt-fw u-boot-nodtb.bin fip.img
+}}}
  * write fip.img in Linux:
 {{{#!bash
-dd if=fip.bin of=/dev/mmcblk0 bs=1M seek=15 # program at 15MiB offset
-}}}
+dd if=fip.img of=/dev/mmcblk0 bs=1M seek=15 # program at 15MiB offset
+}}}
+ * write fip.img in U-Boot:
+{{{#!bash
+tftpboot $loadaddr newport/fip.img && mmc write $loadaddr 0x7800 0x780 # update 960kb at 15mb offset
+}}}
