U-Boot for NanoPi-K2 |
||||
==================== |
||||
|
||||
NanoPi-K2 is a single board computer manufactured by FriendlyElec |
||||
with the following specifications: |
||||
|
||||
- Amlogic S905 ARM Cortex-A53 quad-core SoC @ 1.5GHz |
||||
- ARM Mali 450 GPU |
||||
- 2GB DDR3 SDRAM |
||||
- Gigabit Ethernet |
||||
- HDMI 2.0 4K/60Hz display |
||||
- 40-pin GPIO header |
||||
- 4 x USB 2.0 Host, 1 x USB OTG |
||||
- eMMC, microSD |
||||
- Infrared receiver |
||||
|
||||
Schematics are available on the manufacturer website. |
||||
|
||||
Currently the u-boot port supports the following devices: |
||||
- serial |
||||
- eMMC, microSD |
||||
- Ethernet |
||||
|
||||
u-boot compilation |
||||
================== |
||||
|
||||
> export ARCH=arm |
||||
> export CROSS_COMPILE=aarch64-none-elf- |
||||
> make nanopi-k2_defconfig |
||||
> make |
||||
|
||||
Image creation |
||||
============== |
||||
|
||||
Amlogic doesn't provide sources for the firmware and for tools needed |
||||
to create the bootloader image, so it is necessary to obtain them from |
||||
the git tree published by the board vendor: |
||||

> export FIPDIR=$PWD/fip |
||||
|
||||
Go back to mainline U-Boot source tree then : |
||||
> mkdir fip |
||||
|
||||
> cp $FIPDIR/gxb/bl2.bin fip/ |
||||
> cp $FIPDIR/gxb/acs.bin fip/ |

|

||||

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

||||
|
||||

||||
--input fip/boot_new.bin |
||||
--output fip/u-boot.bin |
||||
|
||||
and then write the image to SD with: |
||||
|
||||
> DEV=/dev/your_sd_device |
||||
> dd if=fip/u-boot.bin of=$DEV conv=fsync,notrunc bs=512 seek=1 |
