1 | U-Boot for Khadas VIM |
2 | ======================= | |
3 | ||
1314bd11 | 4 | Khadas VIM is an Open Source DIY Box manufactured by Shenzhen Wesion |
5ff2ee44 NA |
5 | Technology Co., Ltd with the following specifications: |
6 | ||
7 | - Amlogic S905x ARM Cortex-A53 quad-core SoC @ 2GHz | |
8 | - ARM Mali 450 GPU | |
9 | - 2GB DDR3 SDRAM | |
10 | - 10/100 Ethernet | |
11 | - HDMI 2.0 4K/60Hz display | |
12 | - 40-pin GPIO header | |
13 | - 2 x USB 2.0 Host, 1 x USB 2.0 Type-C OTG | |
14 | - 8GB/16GBeMMC | |
15 | - microSD | |
16 | - SDIO Wifi Module, Bluetooth | |
17 | - Two channels IR receiver | |
18 | ||
19 | Currently the u-boot port supports the following devices: | |
20 | - serial | |
21 | - eMMC, microSD | |
22 | - Ethernet | |
23 | ||
24 | U-Boot compilation | |
25 | ================== | |
26 | ||
27 | > export ARCH=arm | |
28 | > export CROSS_COMPILE=aarch64-none-elf- | |
29 | > make khadas-vim_defconfig | |
30 | > make | |
31 | ||
32 | Image creation | |
33 | ============== | |
34 | ||
35 | Amlogic doesn't provide sources for the firmware and for tools needed | |
36 | to create the bootloader image, so it is necessary to obtain them from | |
37 | the git tree published by the board vendor: | |

50 | Go back to mainline U-Boot source tree then : | |
51 | > mkdir fip | |
52 | ||

89 | --bl31 fip/bl31.img.enc \ | |

92 | and then write the image to SD with: | |
93 | ||
94 | > DEV=/dev/your_sd_device | |
95 | > dd if=fip/u-boot.bin.sd.bin of=$DEV conv=fsync,notrunc bs=512 skip=1 seek=1 | |
96 | > dd if=fip/u-boot.bin.sd.bin of=$DEV conv=fsync,notrunc bs=1 count=444 |
