| 2 | and AOSP images built from sources. |
| 3 | Detailed instructions on how to setup the Board can be found |
| 4 | here: |

| 7 | For flashing the bootloader, the top two links should be installed |
| 8 | (closed) and the 3rd link should be removed (open): |
| 9 | |
| 10 | --------------------------------------------------------- |
| 11 | | Name | Link | State | |
| 12 | | Auto Power up | Link 1-2 | closed | |
| 13 | | Boot Select | Link 3-4 | closed | |
| 14 | | GPIO3-1 | Link 5-6 | open | |
| 15 | --------------------------------------------------------- |
| 16 | |
| 17 | Link 1-2 causes HiKey to auto-power up when power is installed. Link |
| 18 | 3-4 causes the HiKey SoC internal ROM to start up in at a special |
| 19 | "install bootloader" mode which will install a supplied bootloader |
| 20 | from the microUSB OTG port into RAM, and will present itself to a |
| 21 | connected PC as a ttyUSB device. |
| 22 | |
| 23 | Note: The HiKey board will remain in USB load mode for 90 seconds |
| 24 | from power up. If you take longer than 90 seconds to start the install |
| 25 | then power cycle the board before trying again. |
| 26 | |
| 27 | Wait about 5 seconds and then check that the HiKey board has been |
| 28 | recognized by your Linux PC: |
| 29 | $ ls /dev/ttyUSB* |
| 30 | or |
| 31 | $ dmesg |
| 32 | |
| 33 | |
| 34 | Run the flash-all.sh script after building AOSP for hikey with the right |
| 35 | right UART recognised in the above command: |
| 36 | $ ./flash-all.sh /dev/ttyUSBX |
| 37 | |
| 38 | Remove the link 3-4 and power on the board. |
