MySensors on sunxi kernel. A10 Cubieboard.

[Артем ТИхонович]

Hi ! Does anybode run mySensors gateway on sunxi boards? It seem to be Orange pi but in my distro Pins have another definition:
0 lrwxrwxrwx 1 root root 0 Nov 18 17:01 gpio1_ph7 -> ../../devices/platform/gpio-sunxi/gpio/gpio1_ph7
If i set in config like this: -my-rf24-ce-pin=gpio1_ph7
i have a error: ./drivers/RF24/RF24.cpp:52:17: note: in expansion of macro 'MY_RF24_CE_PIN'
hwDigitalWrite(MY_RF24_CE_PIN, level);
if i set simple: --my-rf24-ce-pin=1 mySensors build is ok but i have another error in runtime -
ERROR Could not open /sys/class/gpio/gpio1/direction i suppouse i need to use sunxi headers for correct pin definition but i do not know do it.

@артем-тихонович which os with which kernel version do You run on the cubieboard ?
check if You can do this in the console:

echo 1 > /sys/class/gpio/export
cat /sys/class/gpio/gpio1/direction

there may be also permission problems so try also as root

@rozpruwacz i run ArchLinuxArm:
uname -a
Linux Archey 3.4.103-ARCH+ #4 PREEMPT Mon Dec 22 19:54:28 UTC 2014 armv7l GNU/Linux

This is output:
cat /sys/class/gpio/gpio1_ph7/direction
out

May be problem in names of GPIO pin number + port_pin.
Few years ago i find RF24 library for my Cubieboard A10 but i cant up it.
In this lib gpio defined with macros:
RF24 radio(SUNXI_GPI(14), SUNXI_GPI(15), "/dev/spidev2.0");

 ./configure --spi-spidev-device=/dev/spidev0.0 --my-transport=nrf24 --my-rf24-ce-pin=1 --my-rf24-cs-pin=2  --my-gateway=mqtt --my-controller-ip-address=127.0.0.1 --my-mqtt-publish-topic-prefix=mysensors-out --my-mqtt-subscribe-topic-prefix=mysensors-in --my-mqtt-client-id=mygateway1

./mysgw

if i set --my-rf24-ce-pin=gpio1_ph7 i got an compile error:

@артем-тихонович the 3.4 kernel is the "legacy" kernel and is not compatible with mainline kernel. I would suggest to install os with the mainline kernel. Otherwise you need to change mysensors code.

@rozpruwacz thank you! I just try to build and install mainline kernel. for my board. Now a10 supprot ok in mainline.
