Dear team,
Now my customer is using LDVS of i.MX6Q as 32bit data length.
And they want to change it into 16bit data length.
BTW they are using Linux as an OS.
Could you show me where to change for achieving their requirement?
The customer is using OpenGL(EGL), and they want to handle RGB565(16bit data).
But now they saw the accessing to memory is done by 32bit.
And they want to lower the data length into 16bit access, aiming to speed-up the accessing speed.
They have a doubt whether OpenGL(EGL) of i.MX6Q does support 16bit(RGB565) or not.
Does OpenGL(EGL) of i.MX6Q support RGB565?
Thanks,
Miyamoto
Hi Miyamoto
>Does OpenGL(EGL) of i.MX6Q support RGB565?
yes, RGB565 format is supported by GPU according to Chapter 31,32

this is not implemented in original NXP BSP, one can use

Hello igorpadykov
Thanks for your reply.
Is it possible for me to know how to achieve RGB565 as a general information?
Thanks,
Miyamoto
Hi igorpadykov
Thanks for your support.
One quick question.
You sent me the link to the reference manual of i.MX6QuadPlus/DualPlus.
Actually, the customer is using i.MX6Quad.
Can I understand that GPU of i.MX6Quad also supports RGB565?
BR,
Miyamoto
Hi Miyamoto
sorry for wrong link, yes GPU of i.MX6Quad also supports RGB565.
