No node in /dev to access AD7476 (through IIO Framework)

Hi,

 

I am using 2011R1 HEAD distro, with 2011R1-RC4 toolchain. I am using ADSP BF527 based platform

 

I built the distro as given in http://wiki.analog.com/resources/tools-software/linux-drivers/iio-adc/ad7476a

Note : Blackfin GPIO was used as SPI chipselect instead of any framework based (native SPI) chip selects.

Note : The support for Buffers was also built

 

As given in the above link I was able to read data using the sysfs interface.

I have enabled buffering and am using bfintmr3 as my trigger.

 

Despite being able to read data via sysfs, I found that there was no node in /dev through which I can directly access the device (once it has been configured and enabled through sysfs).

 

What might be the issue ?

Chandrashekhar
