5 - Ensure that your Malta has jumper JP1 fitted. Without this jumper you will
6 be unable to flash your Malta using a Navigator Probe.
8 - Connect Navigator Console to your probe and Malta as usual.
10 - Within Navigator Console run the following commands:
12 source /path/to/u-boot/board/imgtec/malta/flash-malta-boot.tcl
13 reset
14 flash-boot /path/to/u-boot/u-boot.bin
