hi,

 

We were trying to interface a 320*240 RGB Display with i.MX6 development kit by iWave. When interfacing the Display, its not working. We found that the Horizontal and vertical sync are correct but the Main clock which is expected to be around 10Mhz is found to be 50Mhz We were editing the BSP provided by iWave. There was a default 7 inch display in the EVK. Its working good. And the Display frequency of that display if found to be same as 50Mhz. So i think in the base BSP somewhere they have set the frequency to 50Mhz. We are using Innolux LCD.

 

Later I found that a delay should be given during boot up for lcd to initialize. But how to implement it in bootloader?  I need to give a delay for LCD RESET fro some millisec in E-boot.

 

Please share your thoughts.
