尊敬的团队：
我们有用于显示800x480的 OLDI 端口0输出定制板。
当我使用800x480定时我得到半显示器. 高度似乎正常。 宽度有问题
static const struct drm_display_mode custom_mode = {
.clock = 24750,
.hdisplay = 800,
.hsync_start = 800 + 54,
.hsync_end = 800 + 54 + 2,
.htotal = 800 + 54 + 2 + 44,
.vdisplay = 480,
.vsync_start = 480 + 49,
.vsync_end = 480 + 49 + 2,
.vtotal = 480 + 49 + 2 + 22,
};
static const struct panel_desc custom = {
.modes = &custom_mode,
.num_modes = 1,
.bpc = 8,
.size = {
.width = 152,
.height = 91,
},
.delay = {
.prepare = 50,
.disable = 50,
},
.bus_flags = DRM_BUS_FLAG_DE_HIGH,
.bus_format = MEDIA_BUS_FMT_RGB888_1X7X4_JEIDA,
.connector_type = DRM_MODE_CONNECTOR_LVDS,
};但当我使用1600x480时,它显示完整的800x480但不幸的是 modetest 得到1600x480所以,我们为800x480所做的 GUI 崩溃了。
static const struct drm_display_mode custom_mode = {
.clock = 49500,
.hdisplay = 1600,
.hsync_start = 1600 + 54,
.hsync_end = 1600 + 54 + 2,
.htotal = 1600 + 54 + 2 + 44,
.vdisplay = 480,
.vsync_start = 480 + 49,
.vsync_end = 480 + 49 + 2,
.vtotal = 480 + 49 + 2 + 22,
};
static const struct panel_desc custom = {
.modes = &custom_mode,
.num_modes = 1,
.bpc = 8,
.size = {
.width = 152,
.height = 91,
},
.delay = {
.prepare = 50,
.disable = 50,
},
.bus_flags = DRM_BUS_FLAG_DE_HIGH,
.bus_format = MEDIA_BUS_FMT_RGB888_1X7X4_JEIDA,
.connector_type = DRM_MODE_CONNECTOR_LVDS,
};
有什么想法为什么会发生？
这是我们使用 FYR 的叠加
