Hi:

I have a MIPI LCD ,the driver IC is S6D7AA0X04,the LCD brief shows that the data lane is 4,and the pixels is (1280x800) less than 1366*768,if LCD data lane is configurable，Can I drive it with the STM32MP157C？

thanks�?​

Hello,

It should work, with checking on your LCD that it should be set to use 2 data lanes and could support a bandwidth of 1Gbit/s per lane (required to support 1280x800 24bits 60fps).

Hello Patrick,

I have the same question for an MIPI LCD, 4 lanes with the MP1

it seems the LCD cannot be configured to 2 lanes with any pins

LCD chipset = HX8282-A/C / HX8696-A01

Resolution of 1024x600 16.7M and support colors

Tlpxm and Tlpxd are 50nsec Min and 75nsec max.

TTA-SUREs = 2xTlpxd

TTA-GETD = 5xTlpxd

TTA-GOD=4xTlpxd

How to check from the chipset or LCD datasheet it can support the timing ?
