Hello,

-------------------------

my bootargs:

------------------------

It seems as the problem sits somewhere around system/lib/hw/hwcomposer_viv.imx6.so

The kernel is booting up nicely and is showing all four penguins.

I am new in this field and would be very grateful for any advice where i can start from.

Thanks,

Hi Yixing,

i got it managed. I used a too old version of the kerneldriver. After updating it worked fine!

You can close the discussion.

Thanks,
