Hello All, I am trying to get a minimum working example for using SPI on the raspberry pi, however I have been unable to get anything on the SPI ports for several weeks now.
I have tried using the Linux spidev library as recommended by the user guide, however that fails to work. The function calls don't send any errors out, however nothing happens (I've been checking both SPI port pins for activity). A similar thing happens when I run the spi test program located at rtems-git/testsuites/libtests/spi01 in the RTEMS source distribution. None of the assertions fail, but again, nothing happens on either SPI Bus. Following the GSoC submission for SPI on the RPi (https://devel.rtems.org/wiki/GSoC/2013/Raspberry_Pi_BSP_Peripherals) it says that those steps should enable the board to run SPI, however I am unable to replicate his results of proof that SPI works. The autotools parts in the git repo linked on that page won't run as configure.ac is missing. Admittedly my knowledge of autotools is rather limited so that may simply be operator error, but the effort that I've put into getting this working is telling me there has got to be a better way. All I really want is a short list of functions to call and parameters to pass in for spi control and then a simple rx and tx subroutine (hence my first attempt at using spidev). Any advice or help would be much appreciated, Will Busacker _______________________________________________ users mailing list users@rtems.org http://lists.rtems.org/mailman/listinfo/users
