Display image remains same even after executing different demo

[kp030188]

Hi,

I am executing demos on embedded linux board ( using Linux-Framebuffer). I cross compiled few demos for the board. But when i am executing those demos i am facing issue. Same image remains on the display even new demo is executed. For example:- I executed circle demo, circle displayed on screen. After that i executed image_animated demo but still circle displayed on screen. After that aborting this and executing again animated image appeared. This is happening with all the demos, to check output of any demo i have to execute it twice as during 1st run its showing output of previous demo.

Hello and welcome to the community,

This issue has been reported before but unfortunately we didn't have time to investigate ourselves yet and the person that asked the question didn't bother trying to figure out what the problem is. For now, the easy solution is to call the board initialization function twice in the driver.: 

We'd appreciate it if you can have a look at this trying to figure out what the problem might be.

Even after calling driver initialization twice behavior is same. I had to launch executable twice to see the expected result.
