30 | U-Boot compilation | |
31 | ================== | |
32 | ||

37 | Image creation | |
38 | ============== | |
39 | ||
40 | Amlogic doesn't provide sources for the firmware and for tools needed | |
41 | to create the bootloader image, so it is necessary to obtain them from | |
42 | the git tree published by the board vendor: | |

55 | Go back to mainline U-Boot source tree then : | |
56 | > mkdir fip | |

97 | and then write the image to SD with: | |
98 | ||
99 | > DEV=/dev/your_sd_device | |
100 | > dd if=fip/u-boot.bin.sd.bin of=$DEV conv=fsync,notrunc bs=512 skip=1 seek=1 | |
101 | > dd if=fip/u-boot.bin.sd.bin of=$DEV conv=fsync,notrunc bs=1 count=444 |
