I was thinking of getting an RK3399 box. But my application needs to be bale to write to /dev/graphics/fb0. Is this possible for RK3399 device ?. A good way to check it is as follows:
cat /dev/urandom > /dev/graphocs/fb0
You need to be root to do this. If you see random pixels on thescreen then it works. If not it means this feature is not supported.
Can someone run this test ?
Thanks
