⚠️ DEPRECATED: Most of the drivers for Allwiner SoCs have been merged in the mainline kernel, and the meta-sunxi yocto layer seems to have recipes to build it, and machine config for most of the SBCs, at least those mentionned in this repo, that's probably where you should look now.

Build images using yocto for:

• Orange Pi Zero SBC
• Orange Pi Pc SBC
• Orange Pi Pc Plus SBC

Orange Pi Zero

This will build a minimal console image

Runs the 4.19 mainline kernel

This XRADIO X819 WiFi driver for mainline kernel is also in the image as a kernel module and loaded at boot time (firmware binaries for this driver come from here)

The SPI NOR flash memory support is enbled in the kernel and bootloader configuration, so it could be used to run u-boot and boot from USB for example

Orange Pi Pc [Plus]

Runs a 4.17 kernel, with HDMI support and Mali driver

It's the r6p2 fb driver and the matching r6p2 fb user space lib, to be used with QT using the EGLFS platform (eglfs_mali)

⚠️ WIP

The driver is loaded correctly but eglinfo-fb, the qt egl test app and the sunxi-mali test app fails the same way: segfault in libMali.so

mali: loading out-of-tree module taints kernel.
Allwinner sunXi mali glue initialized
Mali: 
Found Mali GPU Mali-400 MP r1p1
Mali: 
2+0 PP cores initialized
Mali:

Build the images

Clone the external submodules :

git submodule update --init

Source the file source-me:

. source-me <machine>

With = "orange-pi-zero", "orange-pi-pc" or "orange-pi-pc-plus"

And build the image:

bitbake <image>

With = "opiz-minimal", "opipc-minimal", "opipcplus-minimal" or "opipc-qt5"

Flash on a sdcard

The rootfs archive, bootloader and kernel images as well as an sdcard image with all needed partitions must have been created in:

build/tmp-glibc/deploy/images/<machine>/

Use dd to flash it on the sdcard (unmount all partitions before):

dd if=build/tmp-glibc/deploy/images/<machine>/<image>-<machine>.sunxi-sdimg of=/dev/??? bs=1M

To create a sdcard with root partition extended to all the device, use this script:

sudo ./flash-sdcard.sh -d /dev/???

Boot

The ethernet network interface is configured as a dhcp client. A sshd is running. Use root for login, no password.

For Orange Pi Zero, The wireless network interface uses wpa_supplicant for its configuration, edit /etc/wpa_supplicant/wpa_supplicant-wlan0.conf to setup the ssid and psk. Or run wpa_passphrase <SSID> <PASSPHRASE> >> /etc/wpa_supplicant/wpa_supplicant-wlan0.conf

Flash u-boot on the SPI NOR flash (Orange Pi Zero)

If your board has been produced with integrated SPI NOR flash memory, you should see its device file:

/dev/mtd0

The distribution provides mtd-utils. Copy the u-boot binary from the image folder on the device:

scp build/tmp-glibc/deploy/images/orange-pi-zero/u-boot-sunxi-with-spl.bin root@<ip>:

Then, on the device:

flash_erase /dev/mtd0 0 128

flashcp u-boot-sunxi-with-spl.bin /dev/mtd0
