CONFIGURABLE CSPI OF imx6

geekdarcy — Fri, 12 Jan 2018 07:37:45 GMT

Hi everyone,

I'm developing a new board based on the IMX6.

I need to interface the Serial SPI LCD display to custom imx6 board using Linux 3.0.35 kernel.

Here is my LCD display which is using ILI9806E( RGB+3LINE-9bit-SPI-COMMAND) controller.

Could I init LCD display by config CSPI1 and how to do it ?

I don't found any related code in the Linux 3.0..35.

How and where could I add some BSP support for the new LCD display .

Any helps.Documents , codes and so on.

Thanks for your help.

Kind Regards.

Hi, igor

Thanks for your reply.

But I need config ECSPI1 for SPI master, not slave.

And I need initialize LCD display by ECSPI1's output.

I had not found any useful reference document in community for I.MX6.

I found source file ,who's mxcfb_epson_vga.c is similar to my situation in Linux 3.0.35 's drivers.

But I am not clear that the driver as my menitoned suit me well.

Any clue about BSP support and LCD drivers, please!

Kind Regards.
