Hello!

As we managed to compile Android for our product (now we use iMX6Q but finally we'll be using iMX6Solo), we have another problem.

We'd like to connect iMX with LCD that has no synchronisation. Is it possible? I've attached datasheet of LCD we'd like to use.

Hi Krzysztof

yes such LCD can be used with i.MX6 (and other i.MX) IPU, for example similar "DE"

configuration is described on Figure 5. LCD Interface between i.MX35 and Chunghwa

Hello Igor, yse - I've just found the AN3974 in another topic and this LCD meets situation we have in our project. But are there any changes needed in kernel to properly drive this LCD? Now we have only 1/4 of screen working.

Hi Krzysztof

this appnote gives detailed guidelines how to add support for new LCD to Linux.

MX53UG Chapter 18 Supporting the i.MX53 Reference Board DISP0 LCD

also gives good description. You can start new thread if wish to elaborate.

Igor, is the iMX Kernel supporting this type of LCDs and I just need to modify BOARD_KERNEL_CMDLINE or I have to add this as a new LCD type?

Hi Krzysztof

no, by default Freescale BSPs support only LCDs used

on Freescale reference boards.

Support for other (new) LCDs should be added modifying software

sources using these documents.
