Hi all
I have question about OCRAM_PXP.
I can't understand which memory use in default in each case
Q1.
Is OCRAM_PXP always used when PXP (rotation, superimposition, CSC) is used ?
Q2.
My recognition is that PXP is not used when outputting from LCDIF to LCD through the camera.
In this case, is it correct that OCRAM_PXP is not used ?

Hello,
OCRAM_PXP mainly is used, when the PXP and LCDIF support a mode where
the internal RAM serves as frame buffer to minimize external memory bandwidth.
Also, You may look at Figure 13-87 (PXP Architecture) of i.MX7D RM, showing Internal
RAM using. So, it is not recommended to use OCRAM_PXP, when the PXP is working.
It is possible to implement data path from CSI camera to LCD without PXP.
Also, please look at About OCRAM_S in i.MX7Solo
Have a great day,
Yuri
