Hi,

I am working on a custom board which is based on i.MX6 solo board.Linux yocto is being used to boot the board . The kernel version is 3.14.38.The issue being faced is ,image size is larger.It is not fitting correctly on LCD.

LCD resolution is 320*240.

modified the dts file based on LCD datasheet.

i have seen the below thread, which tells change pll2 to pll5.

Hello Rizwan,

Please follow the following document Porting LVDS LCD With Low Resolution to i.MX6 , In this document you can see that you need to modify the DTS file and also make some changes in the /arch/arm/mach-mx6/clock.c, there you can modify 3 ldb's clock source : &pll5_video_main_clk, &pll2_pfd_352M, &pll2_pfd_400M,

Have a great day,
TIC
