Orange Pi Plus 2E - SPI problem

Hi everyone,

I am using Armbian. SPI overlay and "spidev" are already loaded

"[    2.614185] spi spi0.1: spi_setup / gpio_is_valid(21) ... doing gpio_request ...
[    2.614213] spi spi0.1: spi_setup / gpio_direction_output(21) done !
[    7.256451] spidev spi0.1: probing from DT
"

Did someone succesfully used SPI on this board using WiringPi, WiringPISPI?

I have an application that returns me "Unable to open SPI device: No such file or directory".

I do have ls /dev/spidev0.1

I tried different libraries for WiringPi but no success.

It seems that the library tries to load another module instead "spidev" that is already loaded in linux.

Do you need another information? I am ready to provide whatever you might need.

Thank you

In case anyone has the same problem, I found this solution:

 

git clone https://github.com/zhaolei/WiringOP.git -b h3

 

then go to WiringOP/wiringPI/

and edit file wiringPiSPI.c

 

These are the lines that I modified 

static const char       *spiDev0  = "/dev/spidev0.0" ;

static const char       *spiDev1  = "/dev/spidev0.1" ;

 

into this:

static const char       *spiDev0  = "/dev/spidev0.1" ;

static const char       *spiDev1  = "/dev/spidev1.0" ;

 

after this, build wiringpi. Error is gone now
