| 12 | Quick Start |
| 13 | ----------- |
| 14 | |
| 15 | - Get and build the ARM Trusted firmware binary |
| 16 | - Get DDR and HDMI firmware |
| 17 | - Build U-Boot |
| 18 | - Install on SD card |
| 19 | - Boot |
| 20 | |
| 21 | Get and build the ARM Trusted firmware binary |
| 22 | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ |
| 23 | |
| 24 | Note: builddir is U-Boot build directory (source directory for in-tree builds) |
| 25 | |
