Frieder, I have been monitoring some of the activity on the BLK_CTL. It seems like there is some disagreement on how to connect the power domain controller with the BLK_CTL. Someone reported that it causes a hang on the 8MP, so until that gets resolved, I doubt we'll be able to use the display system. Some of the DSIM changes happening are being pushed back for further changes, so it seems like having the full integration might be a while. adam > > Thanks, > Frieder
