Hello
I work with imx7sabre. I want use tow buf of Lcd interface (eLCDIF) the primary buf and the AS buf "the buffer to the Alpha Blending Interface". And I want have tow frame buffer (/dev/fb0, /dev/fb1).
- /dev/fb0 to primary buf
- /dev/fb1 to AS buf
But if I read the driver mxsfb.c the Alpha Blending Interface module didn't develop.
Can you help me please?
Best regards
François Delaurat.
Hi François
one can look at pxp examples in unit tests (imx-test package)
check mxc_fb_test, pxp_lib_test
imx-test-5.4.tar.gz

Hello igorpadykov ,
Thanks to your help but the ipu module that use in mxc_fb_test is only to IMX6.
There is not ipu in IMX7.
have you got other idea.

Hi François
had you looked at /pxp_lib_test examples,
it has pixel inversion codes, seems it is possible
to reuse it and modify for alpha blending

Hi igorpadykov ,
Yes, it is possible. But it is with the pxp module. And I already use the pxp module.
In fact I want to merge the result from pxp module with the frame buffer IHM (QT),
to succeed I must use the overlay of lcdif module.
