Drawbitmap/ GUI issue in Free RTOS

Hi,

STM32F429ii

I couldn't load image or draw any pattern from different tasks.

If I load a bootup image from default task (TASK1), and switch over to another task and try to clear the bootup image and draw my own lines and patterns. But the boot up image not goes away from the screen. I couldn't do any thing from another task over the screen.

What could be the reason?

Please help me.

Thanks,

Param.
