Para usar la Orange Pi Zero tendremos que crear imágenes arrancables en tarjetas micro SD.
Dependiendo de donde conectemos la tarjeta tendremos que usar diferentes
rutas. En el procedimiento descrito a continuación ${card} será la
ruta al dispositivo de la tarjeta y ${p} la partición (si la hay).
Si la tarjeta se conecta via adaptador USB, linux la va a asociar a un
dispositivo /dev/sdx, por ejemplo en mi portátil el disco duro es
/dev/sda las distintas particiones serán /dev/sda1, /devb/sda2,
etc.
Si conectamos una memoria con un adaptador USB linux la podría mapear en
/dev/sdb por ejemplo.
Si la memoria se conecta mediante una ranura SD, linux la asociará a un
dispositivo /dev/mmcblk0 o /dev/mmcblk1, etc. etc. Dependerá de la
ranura usada. Las particiones en este tipo de dispositivos tienen rutas
como por ejemplo /dev/mmcblk0p1.
Los datos se pueden almacenar directamente en la memoria SD o en una partición creada en la memoria.
Resumiendo:
${card}será/dev/sdbo/dev/mmcblk0- car**d{p} será
/dev/sdb1o/dev/mmcblk0p1
Antes de seguir adelante hay que estar completamente seguro del dispositivo asociado a nuestra memoria SD para no armar ningún estropicio.
Hay varias comprobaciones que se pueden hacer:
dmesg |tail nos permitirá echar un ojo a los últimos mensajes en el
log del sistema. Si acabamos de insertar la memoria veremos el
dispositivo usado.
sudo fdisk -l nos permite ver las particiones montadas en nuestro
linux, por ejemplo con mi SD en la ranura SD de mi portatil la salida es
(entre otras cosas, he obviado las particiones de los discos duros):
Disk /dev/mmcblk0: 7.4 GiB, 7948206080 bytes, 15523840 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x00000000
cat /proc/partitions también nos dará una lista de particiones, en mi
portátil las que interesan son:
179 0 7761920 mmcblk0
179 1 7757824 mmcblk0p1
Descargamos la imagen de Jessie adaptada a la Orange Pi Zero desde la página https://www.armbian.com/download/
Descomprimimos la imagen y la grabamos en la tarjeta SD con el comando:
sudo dd if=./Armbian_5.24_Orangepizero_Debian_jessie_3.4.113.img of=/dev/mmcblk0
Insertamos la tarjeta en la Orange Pi y le damos alimentación. El primer arranque llevará alrededor de tres minutos, y tras ese tiempo aun hará falta un minuto más para poder hacer login. Este retardo es debido a que el sistema intentará actualizar la lista de paquetes y creará un area de swap de emergencia en la SD, y además cambiará el tamaño de la partición que hemos creado para ocupar todo el espacio libre en la SD.
De momento solo la he arrancado y efectivamente las particiones han cambiado tras el arranque así que tiene buena pinta.
Volvemos a insertar la SD en la Orange Pi y la conectamos con un cable ethernet al router de casa. El Armbian viene configurado por defecto para obtener su IP desde un servidor DHCP.
Como mi cutre-router no me da información de las IP asignadas usamos nmap:
nmap -sP 192.168.0.0/24
Con eso averiguamos la IP asignada a la Orange Pi Zero y ya podemos hacer login con el siguiente comando [1]:
¡Y ya estamos!
Lo primero es poner al dia el sistema:
apt-get update
apt-get upgrade
Si quieres puedes reconfigurar el time zone:
dpkg-reconfigure tzdata
Vamos a comprobar que todo va bien:
root@orangepizero:~# iwconfig
lo no wireless extensions.
tunl0 no wireless extensions.
wlan0 IEEE 802.11bgn ESSID:off/any
Mode:Managed Access Point: Not-Associated Tx-Power=20 dBm
Retry long limit:7 RTS thr:off Fragment thr:off
Encryption key:off
Power Management:on
eth0 no wireless extensions.
Todo tiene buena pinta, vamos a ver si detecta WIFIs:
root@orangepizero:~# iwlist wlan0 scan |grep ESSID
ESSID:"wificlientesR"
ESSID:"casa_de_verano"
ESSID:"MOVISTAR_BEEF"
ESSID:"wificlientesR"
ESSID:"R-wlan90"
ESSID:"MOVISTAR_BAAF"
ESSID:"ababab"
ESSID:"WLAN 77"
ESSID:"castillo"
ESSID:"unaWifi"
ESSID:""
ESSID:"mikasa"
Para configurar el wifi echamos un ojo al fichero
/etc/network/interfaces pero en ese mismo fichero encontramos el
aviso:
# Armbian ships with network-manager installed by default. To save you time
# and hassles consider using 'sudo nmtui' instead of configuring Wi-Fi settings
# manually.
Así que basta con ejecutar sudo nmtui y ya podemos dar de alta nuestra
wifi (yo la prefiero con IP estática).
Ejecutamos ifconfig y ya vemos nuestro nuevo interface configurado:
ifconfig
wlan0 Link encap:Ethernet HWaddr a4:7c:f2:9a:97:7c

La tarjeta de desarrollo Orange Pi Zero viene equipada con un procesador Cortex A7 Allwinner H2+ quad core, con 256 o 512MB RAM, Ethernet, y puertos USB. Disponible en Aliexpress (tienda oficial) por 6.99 dolares, mas 3.39 dolares como gastos de envío.
- SoC – Allwinner H2(+) quad core Cortex A7 processor @ 1.2 GHz with Mali-400MP2 GPU @ 600 MHz
- System Memory – 256 to 512 MB DDR3-1866 SDRAM
- Storage – micro SD card slot
- Connectivity – 10/100M Ethernet + 802.11 b/g/n WiFi (Allwinner XR819 WiFi module) with u.FL antenna connector and external antenna
- USB – 1x USB 2.0 host ports, 1x micro USB OTG port
- Expansion headers – Unpopulated 26-pin “Raspberry Pi B+” header + 13-pin header with headphone, 2x USB 2.0, TV out, microphone and IR receiver signals
- Debugging – Unpopulated 3-pin header for serial console
- Misc – 2x LEDs
- Power Supply – 5V via micro USB port or optional PoE
- Dimensions – 52 x 46 mm
- Weight – 26 grams
Un excelente esquema de pines puede conseguirse en OSHLab
El mapeado de los pines de la Orange (de los micros Allwinner en realidad) en el kernel de Linux viene dado por la formula:
(Position of letter in alphabet - 1) * 32 + Pin number
Para todos los pines PA de nuestra Orange Pi Zero, el número del kernel coincide con el del pin. Pero para los pines PG06 y PG07 se corresponden con los códigos 198 y 199.
Pueden bajarse de aquí
La memoria es más que suficiente para correr programas. El Armbian consume únicamente 40Mb en funcionamiento.

Swap: 131068 0 131068
Vamos a hacer algunas pruebas con el hardware. En Armbian, como todo Unix que se precie, todo es un fichero.
En el directorio /sys/class encontraremos cosas interesantes:
root@orangepizero:~# ls /sys/class
backlight cuse graphics i2c-dev mdio_bus power_supply script spidev thermal video4linux
bdi devfreq hdmi ieee80211 mem ppp scsi_device spi_master tty vtconsole

bsg dma hwmon leds mmc_host rfkill scsi_host sunxi_dump usb_device
cedar_dev gpio i2c-adapter lirc net rtc sound sunxi_info vc
Si miramos dentro del directorio leds veremos que hay un directorio
que representa cada uno de los leds de la placa:
root@orangepizero:~# cd /sys/class/leds/
root@orangepizero:/sys/class/leds# ls
green_led red_led
Podemos ver, por ejemplo, a que evento está asociado cada led ejecutando
cat green_led/trigger (tiene el valor default_on) o
cat red_led/trigger (tiene el valor none).
root@orangepizero:/sys/class/leds# cat green_led/trigger
none mmc0 mmc1 timer heartbeat backlight [default-on] rfkill0 phy1rx phy1tx phy1assoc phy1radio
root@orangepizero:/sys/class/leds# cat red_led/trigger
[none] mmc0 mmc1 timer heartbeat backlight default-on rfkill0 phy1rx phy1tx phy1assoc phy1radio
O podemos encender el led rojo ejecutando echo 1 > red_led/brightness,
y para apagarlo ya os podéis imaginar que es
echo 0 > red_led/brightness.
Podemos ver los GPIO disponibles ejecutando:
root@orangepizero:~# cat /sys/kernel/debug/gpio
GPIOs 0-383, platform/sunxi-pinctrl, sunxi-pinctrl:
gpio-10 (? ) out hi
gpio-17 (red_led ) out lo
gpio-202 (xradio_irq ) in lo
gpio-354 (? ) out hi
gpio-362 (green_led ) out hi
Podemos activar un nuevo puerto GPIO, digamos el 15:
root@orangepizero:~# echo 15 >/sys/class/gpio/export
Ahora veremos el puerto activo:
root@orangepizero:~# cat /sys/kernel/debug/gpio
GPIOs 0-383, platform/sunxi-pinctrl, sunxi-pinctrl:
gpio-10 (? ) out hi
gpio-15 (sysfs ) in lo
gpio-17 (red_led ) out lo
gpio-202 (xradio_irq ) in lo
gpio-354 (? ) out hi
gpio-362 (green_led ) out hi
En el directorio /sys/class/gpio/gpio15/ tendremos los interfaces
usuales para puertos gpio definidos en el kernel de linux.
Para probar bibliotecas de Python instalamos:
sudo aptitude install python-pip
sudo aptitude install python-virtualenv
sudo aptitude install python-dev
El caso es que el virtualenv no me funciona después de ejecutar estos pasos. Finalmente he tenido que ejecutar, como root, los siguientes comandos:
pip install --upgrade pip
pip install --upgrade virtualenv
Despues de eso ya he podido usar virtualenv sin problemas.
Tenemos dos repos disponibles:
El repositorio original con las librerías gpio para H3:
git clone https://github.com/duxingkei33/orangepi_PC_gpio_pyH3
Y un fork del repositorio original ya adaptado a la Orange Pi Zero (que es el que usaremos):
git clone https://github.com/nvl1109/orangepi_PC_gpio_pyH3
IMPORTANTE: Si usamos el repositorio original tenemos que revisar el
fichero orangepi_PC_gpio_pyH3/pyA20/gpio/mapping.h
Por ejemplo: la definicion de STATUS_LED debe quedar en el GPA17 en lugar de GPA15:
{ "STATUS_LED", SUNXI_GPA(17), 2 },
Nos clonamos el repo. Vamos a hacer todas las pruebas desde la cuenta de root.
Creamos un entorno para pruebas y lo activamos:
virtualenv test_pyH3_zero
source test_pyH3_zero/bin/activate
Compilamos la biblioteca:
cd orangepi_PC_gpio_pyH3
python setup.py install
Y ya podemos probar los ficheros de ejemplo:
examples/blink_led.py
examples/blink_POWER_STATUS_PL10.py
El resto de ejemplos no van a funcionar, están escritos para la A20-OLinuXino-MICRO
La biblioteca de Python orangepi_PC_gpio_pyH3, en realidad se basa en bibliotecas escritas en C que tenemos disponibles dentro del repo en el directorio pyA20
cd pyA20
ls
gpio/ i2c/ __init__.py spi/ utilities/
Nos interesa probar las bibliotecas en los directorios gpio e i2c, al menos de momento. Serían gpio_lib e i2c_lib respectivamente.
Probamos el acceso al gpio desde C con un programa sencillo que nos haga encender y apagar el led de la OPI.
#include <gpio_lib.h>
sunxi_gpio_init();
sunxi_gpio_set_cfgpin(SUNXI_GPA(17), SUNXI_GPIO_OUTPUT);
while(1) {
sunxi_gpio_output(SUNXI_GPA(17), 1);
sleep(1);
sunxi_gpio_output(SUNXI_GPA(17), 0);
sleep(1);
}
Esta biblioteca imita a la WiringPI que se usa con Raspberry Pi.
Tenemos un fork que viene preparado para la Orange Pi Zero disponible aquí:
https://github.com/xpertsavenue/WiringOP-Zero
GPIO funciona completamente y al parecer aun no han testeado el i2c (tiene mala pinta)
Para compilarla seguimos las instrucciones:
git clone https://github.com/xpertsavenue/WiringOP-Zero
cd WiringOP-Zero
chmod +x ./build
sudo ./build
Podemos comprobar que todo se ha instalado correctamente:

b. Additional offer from the Licensor -- Adapted Material.
Every recipient of Adapted Material from You
automatically receives an offer from the Licensor to
exercise the Licensed Rights in the Adapted Material
under the conditions of the Adapter's License You apply.
c. No downstream restrictions. You may not offer or impose
any additional or different terms or conditions on, or
apply any Effective Technological Measures to, the
Licensed Material if doing so restricts exercise of the
Licensed Rights by any recipient of the Licensed
Material.
6. No endorsement. Nothing in this Public License constitutes or
may be construed as permission to assert or imply that You
are, or that Your use of the Licensed Material is, connected
with, or sponsored, endorsed, or granted official status by,
the Licensor or others designated to receive attribution as
provided in Section 3(a)(1)(A)(i).
b. Other rights.
1. Moral rights, such as the right of integrity, are not
licensed under this Public License, nor are publicity,
privacy, and/or other similar personality rights; however, to
the extent possible, the Licensor waives and/or agrees not to
assert any such rights held by the Licensor to the limited
extent necessary to allow You to exercise the Licensed
Rights, but not otherwise.
2. Patent and trademark rights are not licensed under this
Public License.
3. To the extent possible, the Licensor waives any right to
collect royalties from You for the exercise of the Licensed
Rights, whether directly or through a collecting society
under any voluntary or waivable statutory or compulsory
licensing scheme. In all other cases the Licensor expressly
reserves any right to collect such royalties.
Section 3 -- License Conditions.

reasonable manner based on the medium, means, and context in
which You Share the Licensed Material. For example, it may be
reasonable to satisfy the conditions by providing a URI or
hyperlink to a resource that includes the required
information.
3. If requested by the Licensor, You must remove any of the

reasonably practicable.

In addition to the conditions in Section 3(a), if You Share

license with the same License Elements, this version or
later, or a BY-SA Compatible License.

in any reasonable manner based on the medium, means, and
context in which You Share Adapted Material.

or conditions on, or apply any Effective Technological
Measures to, Adapted Material that restrict exercise of the
rights granted under the Adapter's License You apply.
Section 4 -- Sui Generis Database Rights.
Where the Licensed Rights include Sui Generis Database Rights that
apply to Your use of the Licensed Material:
a. for the avoidance of doubt, Section 2(a)(1) grants You the right
to extract, reuse, reproduce, and Share all or a substantial
portion of the contents of the database;
b. if You include all or a substantial portion of the database
contents in a database in which You have Sui Generis Database
Rights, then the database in which You have Sui Generis Database
Rights (but not its individual contents) is Adapted Material,
including for purposes of Section 3(b); and
c. You must comply with the conditions in Section 3(a) if You Share
all or a substantial portion of the contents of the database.
For the avoidance of doubt, this Section 4 supplements and does not
replace Your obligations under this Public License where the Licensed
Rights include other Copyright and Similar Rights.
Section 5 -- Disclaimer of Warranties and Limitation of Liability.
a. UNLESS OTHERWISE SEPARATELY UNDERTAKEN BY THE LICENSOR, TO THE
EXTENT POSSIBLE, THE LICENSOR OFFERS THE LICENSED MATERIAL AS-IS
AND AS-AVAILABLE, AND MAKES NO REPRESENTATIONS OR WARRANTIES OF
ANY KIND CONCERNING THE LICENSED MATERIAL, WHETHER EXPRESS,
IMPLIED, STATUTORY, OR OTHER. THIS INCLUDES, WITHOUT LIMITATION,
WARRANTIES OF TITLE, MERCHANTABILITY, FITNESS FOR A PARTICULAR
PURPOSE, NON-INFRINGEMENT, ABSENCE OF LATENT OR OTHER DEFECTS,
ACCURACY, OR THE PRESENCE OR ABSENCE OF ERRORS, WHETHER OR NOT
KNOWN OR DISCOVERABLE. WHERE DISCLAIMERS OF WARRANTIES ARE NOT
ALLOWED IN FULL OR IN PART, THIS DISCLAIMER MAY NOT APPLY TO YOU.
b. TO THE EXTENT POSSIBLE, IN NO EVENT WILL THE LICENSOR BE LIABLE
TO YOU ON ANY LEGAL THEORY (INCLUDING, WITHOUT LIMITATION,
NEGLIGENCE) OR OTHERWISE FOR ANY DIRECT, SPECIAL, INDIRECT,
INCIDENTAL, CONSEQUENTIAL, PUNITIVE, EXEMPLARY, OR OTHER LOSSES,
COSTS, EXPENSES, OR DAMAGES ARISING OUT OF THIS PUBLIC LICENSE OR
USE OF THE LICENSED MATERIAL, EVEN IF THE LICENSOR HAS BEEN
ADVISED OF THE POSSIBILITY OF SUCH LOSSES, COSTS, EXPENSES, OR
DAMAGES. WHERE A LIMITATION OF LIABILITY IS NOT ALLOWED IN FULL OR
IN PART, THIS LIMITATION MAY NOT APPLY TO YOU.
c. The disclaimer of warranties and limitation of liability provided
above shall be interpreted in a manner that, to the extent
possible, most closely approximates an absolute disclaimer and
waiver of all liability.
Section 6 -- Term and Termination.
a. This Public License applies for the term of the Copyright and
Similar Rights licensed here. However, if You fail to comply with
this Public License, then Your rights under this Public License
terminate automatically.
b. Where Your right to use the Licensed Material has terminated under
Section 6(a), it reinstates:
1. automatically as of the date the violation is cured, provided
it is cured within 30 days of Your discovery of the
violation; or
2. upon express reinstatement by the Licensor.
For the avoidance of doubt, this Section 6(b) does not affect any
right the Licensor may have to seek remedies for Your violations
of this Public License.
c. For the avoidance of doubt, the Licensor may also offer the
Licensed Material under separate terms or conditions or stop
distributing the Licensed Material at any time; however, doing so

License.

conditions on any use of the Licensed Material that could lawfully
be made without permission under this Public License.
b. To the extent possible, if any provision of this Public License is
deemed unenforceable, it shall be automatically reformed to the
minimum extent necessary to make it enforceable. If the provision
cannot be reformed, it shall be severed from this Public License
without affecting the enforceability of the remaining terms and
conditions.
c. No term or condition of this Public License will be waived and no
failure to comply consented to unless expressly agreed to by the
Licensor.
d. Nothing in this Public License constitutes or may be interpreted
as a limitation upon, or waiver of, any privileges and immunities
that apply to the Licensor or You, including from the legal
processes of any jurisdiction or authority.
