| − | === Setup ===
| |
| − | <pre>git clone https://gitlab.denx.de/u-boot/u-boot.git
| |
| − | cd u-boot
| |
| − | make orangepi-rk3399_defconfig</pre>

| |
| − | ==== Option 1: Package the image with Rockchip miniloader ====
| |
| − | <pre>
| |
| − | - Compile U-Boot
| |
| − |
| |
| − | => cd /path/to/u-boot
| |
| − | => make orangepi-rk3399_defconfig
| |
| − | => make
| |
| − |
| |
| − | - Get the rkbin
| |
| − |
| |
| − | => git clone https://github.com/rockchip-linux/rkbin.git
| |
| − |
| |
| − | - Create trust.img
| |
| − |
| |
| − | => cd /path/to/rkbin
| |
| − | => ./tools/trust_merger RKTRUST/RK3399TRUST.ini
| |
| − |
