@luz I got it from there only, Thanks.

However I am able to access the GPIO 18 with sysfs interface, to make it hgh-low.

Re: Controlling WS2812 device (RGB LED strip)

I have ported the above mentioned ws2812 driver in to latest SDK running kernel 4.14.
Driver source: https://github.com/jnweiger/ws2812_sprites/tree/master/carambola2/package/ws2812_draiveris/src
I haven't modified anything in the driver except #include <asm/uaccess.h> to #inlclude <linux/uaccess.h> as the asm/uaccess.h was throwing error of incompatibility.

After compiling it successfully for omega2, i am able to insert it successfully via insmod, the dmesg shows appropriate logs as well.
But when I try to write to glow LEDs(echo "}!!!}!!!}" > /dev/ws2812) it does not show any effect on the specified GPIO pin.

I am using GPIO 18 and my LED has 5 leds in it; I am following below sequence,
insmod ws2812_driveris.ko gpios=18 leds_per_gpio=5
echo "}!!!}!!!}" > /dev/ws2812

This does not have any effect on LEDs, LEDs are in Off state.

I am suspecting that the low level GPIO registers which are being written/read in the driver are not for Omega2.
Help me to understand this better!

Thanks in advance.
