Hello,
I'm using I AM3352 own board with the TI Linux SDK 07.00.00.00 version on it.
Now I would like to use the ADC in my user space, I followed the Sitara Linux SDK ADC and I came to the thought that the only thingI must do is to add some code to the device tree file.
So in my device tree file I added the following:
&tscadc{
status = "okay";
adc { ti,adc-channels = <6 7>; };
};
After compiling and startup the board, I have no iio avaliable in my /sys/bus, so how can I acces the adc?
Also I saw the following errors when booting up:
[ 0.131070] platform mpu.1: FIXME: clock-name 'fck' DOES NOT exist in dt!
[ 0.131897] platform 49000000.edma: FIXME: clock-name 'fck' DOES NOT exist in dt!
[ 0.132839] OMAP GPIO hardware version 0.1
[ 0.139038] platform 56000000.sgx: FIXME: clock-name 'fck' DOES NOT exist in dt!
The fck is mentioned in the am33x.dtsi file unther the tscadc.
Thanks in advanced.
