Hi,

    I am currently doing the 8080 LCD driver porting on IMX7D device. I am using u-boot 2020.04, kernel 4.14.98 and Android 9 for my system. My porting work was almost done, but Android graph is not showing in my LCD. It shows the logo which u-boot set.

In my kernel debugging messages it shows that "mxsfb 30730000.lcdif: Using uboot framebuffer @ 81cc0000", which seems framebuffer are successfully transfered to Android. But, anyway there is no android display refreshing in framebuffer. Could you help me with that?
