i.MX6/7 PXP LUT Usage for CFA EPD Panel

[mayliu]

Hi,

Since we want use the PXP engine in i.MX6/7 to do RGB444/RGB565 to RGBW4444 CFA conversion, does anyone know the following things?

1. How to load the LUT binary file to i.MX6/7 (Related to PXP_LUT_CTRL, PXP_LUT_ADDR, PXP_LUT_DATA and PXP_LUT_EXTMEM registers)?

2. What PXP registers should be configured in order to light up an CFA EPD Panel?

Thanks!

Hi May

1. one can look at examples in unit-test imx-test 5.2,  pxp_test.c

http://downloads.yoctoproject.org/mirror/sources/imx-test-5.2.tar.gz

2. one can check descriptions in attached Linux Manual, in particular

Chapter 11 Pixel Pipeline (PxP), Chapter 12 ELCDIF Frame Buffer Driver

Best regards

igor
