Hi，
I use a hdmi panel with rockpi 3a board，the board connect to this hdmi panel only, this panel resolution is 1080x1920@60, and I add a panel configure in uboot/common/edid.c，like below code, then the panel can show logo in uboot and kernel。
/* 5'. vic:16 - 1080x1920@60Hz */
{ DRM_BASE_MODE(137520, 1080, 1112,
1144, 1184, 1920, 1928, 1932, 1936, 10,
DRM_MODE_FLAG_NHSYNC | DRM_MODE_FLAG_NVSYNC),
.vrefresh = 60, .picture_aspect_ratio = HDMI_PICTURE_ASPECT_16_9, },
But the board boot to android, the panel can not show android boot logo and UI, it keep show kernel logo only, and I use adb tool to get screenshots, I can see the android UI !
when I reboot to recovery mode, the panel can show recovery mode UI.
Any help was greatly appreciated!
