Dear Members,

 

I am working on to bring up 3.14.30 linux kernel on custom i.MX6 solo based platform. I have added all the required code from 3.14.28 (i.e. 3.14.28_1.0.0_ga release) to

3.14.30 and with this kernel hangs while booting just after loading the "galcore" vivante graphics driver. I tried making "galcore.ko" as a module and it also hangs while

loading. Just for information my LCD and HDMI display are working fine (tested with fb application).

 

I have also tested platform with (3.14.28_1.0.0_ga release + our custom changes) and gpu works fine there.

 

Could someone give some pointers what might be going wrong here? or Has anyone faced similar issues on some other kernel?

 

Waiting for your suggestion/comments/ideas to fix this.
