| 2 | ======================= |
| 3 | |
| 4 | S400 is a reference board manufactured by Amlogic with the following |
| 5 | specifications: |
| 6 | |
| 7 | - Amlogic A113DX ARM Cortex-A53 quad-core SoC @ 1.2GHz |
| 8 | - 1GB DDR4 SDRAM |
| 9 | - 10/100 Ethernet |
| 10 | - 2 x USB 2.0 Host |
| 11 | - eMMC |
| 12 | - Infrared receiver |
| 13 | - SDIO WiFi Module |
| 14 | - MIPI DSI Connector |
| 15 | - Audio HAT Connector |
| 16 | - PCI-E M.2 Connectors |
| 17 | |
| 18 | Schematics are available from Amlogic on demand. |
| 19 | |
| 20 | Currently the u-boot port supports the following devices: |
| 21 | - serial |
| 22 | - eMMC |
| 23 | - Ethernet |
| 24 | - I2C |
| 25 | - Regulators |
| 26 | - Reset controller |
| 27 | - Clock controller |
| 28 | - USB Host |
| 29 | - ADC |
| 30 | |
| 31 | u-boot compilation |
| 32 | ================== |
| 33 | |
| 34 | > export ARCH=arm |
| 35 | > export CROSS_COMPILE=aarch64-none-elf- |
| 36 | > make s400_defconfig |
| 37 | > make |
| 38 | |
| 39 | Image creation |
| 40 | ============== |
| 41 | |
| 42 | Amlogic doesn't provide sources for the firmware and for tools needed |
| 43 | to create the bootloader image, so it is necessary to obtain them from |
| 44 | the git tree published by the board vendor: |

| 56 | |
| 57 | Go back to mainline U-boot source tree then : |

| 106 | and then write the image to SD with: |
| 107 | |
| 108 | > DEV=/dev/your_sd_device |
| 109 | > dd if=fip/u-boot.bin.sd.bin of=$DEV conv=fsync,notrunc bs=512 skip=1 seek=1 |
