Hi, Freescale

I use g2d for image scale,my call order as below:

g2d_open(&mhG2d)

g2d_alloc

g2d_make_current(mhG2d, G2D_HARDWARE_2D)

...

But it failed on g2d_make_current,it is indicate "g2d_make_current: invalid g2d thread context !",what is wrong with this call order? How can i fixed?

Hello Yong,

Your memory allocation in your order it is incorrect. Please check document provided at: Re: GPU3D Driver Support

Section 9 GPU memory, for instructions to change this reserved memory space.

Something like

nSrcBufSize = 3220800;

g2d_alloc(nSrcBufSize, 0);
