添加rk628的dtsi之后开机hdmi屏不亮
在rk3568-firefly-roc-pc-se.dts添加了#include "rk3568-firefly-roc-pc-se-tf-hdmi-mipi-rk628.dtsi" 然后重新编译kernel、打包、烧录之后板子连接的HDMI屏不亮,不知道是哪里的问题。初步怀疑分辨率的问题
开机串口log里面:
hdmi@fe0a0000:detailed mode clock 74250 kHz, flags
H: 1280 1390 1430 1650
V: 0720 0725 0730 0750
bus_format: 100a
VOP update mode to: 1280x720p60, type: HDMI0 for VP0
对比官方固件的开机log:
VOP update mode to: 1920x1080p60, type: HDMI0 for VP0
不知道是不是这里的原因,如果是的话怎么修改?
请大佬帮忙看一下,谢谢!
应该是配置有问题 应该是dts配置有问题,但不知道怎么改 Rockchip UBOOT DRM driver version: v1.0.1
VOP have 3 active VP
vp0 have layer nr:3, primary plane: 4
vp1 have layer nr:2, primary plane: 5
vp2 have layer nr:1, primary plane: 3

log 中可以看到这里i2c通讯失败了,edid没有读取到,因此默认会以1280x720p60的分辨率显示,但不应该出现完全没有显示,628d部分的dts不会影响到hdmi, 可能需要检查下是否有接触不良或者更换hdmi线再试一下 m00_b_rk628-csi 4-0050: timing err, htotal:0, vtotal:0
628d 出现timing err,可能也跟接触不良有关,建议断电重新接一下或者检查更换排线 好的,谢谢
