Installing NXDRV-SPI-Driver on a Raspberry Pi
This installing guide provides the installation requirements.
Requirements
- cmake
- ccmake (optional)
Installing requirements
Install cmake
$ apt-get install cmake
Install ccmake (optional)
$ apt-get install cmake-curses-gui
Installing libcifx
Extract the sources from the zip-file.
$ tar xf <driver_version>.tar.gz
Change to the libcifx directory.
$ cd <driver_version>/driver/libcifx/
(Optional) Create a build directory.
pi@raspberrypi:~/V2.1.1.0/V2.1.1.0/driver/libcifx $ mkdir build && cd build pi@raspberrypi:~/V2.1.1.0/V2.1.1.0/driver/libcifx/build $
Configure CMake environment with ccmake (optional).
pi@raspberrypi:~/V2.1.1.0/V2.1.1.0/driver/libcifx/build $ ccmake ..
Enable SPM_PLUGIN and DISABLE_PCI.
Press "c" to configure cmake and then "g" to generate make file.
Configure CMake environment without ccmake.
pi@raspberrypi:~/V2.1.1.0/V2.1.1.0/driver/libcifx/build $ cmake .. -DDISABLE_PCI=ON -DSPM_PLUGIN=ON
Build and install libcifx.
pi@raspberrypi:~/V2.1.1.0/V2.1.1.0/driver/libcifx/build $ make all pi@raspberrypi:~/V2.1.1.0/V2.1.1.0/driver/libcifx/build $ make install
Compiling the example programs
Go to the examples folder.
pi@raspberrypi:~ $ cd V2.1.1.0/V2.1.1.0/examples/ pi@raspberrypi:~/V2.1.1.0/V2.1.1.0/examples $
Create a build directory.
pi@raspberrypi:~/V2.1.1.0/V2.1.1.0/examples $ mkdir build && cd build pi@raspberrypi:~/V2.1.1.0/V2.1.1.0/examples/build $
Configure CMake environment
pi@raspberrypi:~/V2.1.1.0/V2.1.1.0/examples/build $ cmake ..
Build all source modules
pi@raspberrypi:~/V2.1.1.0/V2.1.1.0/examples/build $ make all
Please do not forget to activate SPI interface on your Raspberry Pi!
Issues during build process
While compiling cifxtcpserver example, this error appears.
Error: multiple definition of 'g_ptMutex'
Quick solution: In TCPServer.c located under <driver_version>examples/cifXTCPServer/, line 56 replace pthread_mutex_t* g_ptMutex to e.g static pthread_mutex_t* s_ptMutex and replace g_ptMutex to s_ptMutex.
Connect a netX90 based device to the Raspberry Pi
netSHIELD90 and Raspberry Pi pinout
Make sure to configure your netx90 based device via netX Studio.
Run cifxspisample. You should get a similar output
pi@raspberrypi:~/V2.1.1.0/V2.1.1.0/examples/build $ sudo ./cifxsample
