Hello,
I successfully applied the 2.1 public binary file according to the following instructions:

Then I successfully installed the Mali drivers to enable hardware accelleration according to the following instructions:

After that my device cannot be booted anymore and I get the error message 'Enlightenment has closed unexpectedly'. It appears that the Mali drivers referenced above are for Tizen 2.0, not for Tizen 2.1.
The correct version of the Mali drivers for Tizen 2.1 can be downloaded from:
