MIPS Malta board
|
||||||
|
|
||||||
|
How to flash using a MIPS Navigator Probe:
|
||||||
|
|
||||||
|
- Ensure that your Malta has jumper JP1 fitted. Without this jumper you will
|
||||||
|
be unable to flash your Malta using a Navigator Probe.
|
||||||
|
|
||||||
|
- Connect Navigator Console to your probe and Malta as usual.
|
||||||
|
|
||||||
|
- Within Navigator Console run the following commands:
|
||||||
|
|
||||||
|
source /path/to/u-boot/board/malta/flash-malta-boot.tcl
|
||||||
|
reset
|
||||||
|
flash-boot /path/to/u-boot/u-boot.bin
|
||||||
|
|
||||||
|
- You should now be able to reboot your Malta to a U-boot shell.
