Hi,

 

I try to use the SPI port on BF537-STAMP, then I compile a new image (uClinuxR9), including the driver and test application spidev_test, but when I run the application an error message is displayed:

 

root: /> spidev_test -D /dev/spidev0.5

can't open device: No such file or directory

Abort

 

when I look in the directory "/dev/" I don't find the driver "spidev0.5"!

 

Best regards

 

Badr

Hi,

 

Yes, I have seen the documentation, Well I configure device ressource, and I add init/exit functions but I'm still unable to see "spidev0.5" in "/dev/" folder

 

Best regards
