IMX8M平台 linux系统 

rm67191的配置:

static const struct display_timing rad_default_timing = {
.pixelclock = { 66000000, 132000000, 132000000 },
.hactive = { 1080, 1080, 1080 },
.hfront_porch = { 20, 20, 20 },
.hsync_len = { 2, 2, 2 },
.hback_porch = { 34, 34, 34 },
.vactive = { 1920, 1920, 1920 },
.vfront_porch = { 10, 10, 10 },
.vsync_len = { 2, 2, 2 },
.vback_porch = { 4, 4, 4 },
.flags = DISPLAY_FLAGS_HSYNC_LOW |
DISPLAY_FLAGS_VSYNC_LOW |
DISPLAY_FLAGS_DE_LOW |
DISPLAY_FLAGS_PIXDATA_NEGEDGE,
};

系统 启动过程 中出现4个企鹅图标,但有线条扯动的横线。进入开机画面,完成后就黑屏

使用

root@imx8mqevk:/unit_tests/Display# ./autorun-fb.sh

i测试时,颜色变化基本正常。

测试完成

停留的画面明显周期性的闪动:

显示正常的图片应当是:

pastedImage_3.png

使用的是lcdif接口配置,原厂默认配置。

请协助。。。
