Other Parts Discussed in Thread: AM4372
Hi,
I am migrating to newer kernel ver. 5.10 from 5.4. I am able to boot the board and get file system loaded and console working. However, the display is not coming up just the backlight is turned on.
On the console I am getting this error: Unable to find DSS platform device.
Below is Linux config for dss.
CONFIG_FB_OMAP2_DSS_INIT=y
CONFIG_FB_OMAP2_DSS=y
CONFIG_FB_OMAP2_DSS_DEBUG=y
# CONFIG_FB_OMAP2_DSS_DEBUGFS is not set
CONFIG_FB_OMAP2_DSS_DPI=y
# CONFIG_FB_OMAP2_DSS_VENC is not set
# CONFIG_FB_OMAP4_DSS_HDMI is not set
# CONFIG_FB_OMAP5_DSS_HDMI is not set
# CONFIG_FB_OMAP2_DSS_SDI is not set
# CONFIG_FB_OMAP2_DSS_DSI is not set
CONFIG_FB_OMAP2_DSS_MIN_FCK_PER_PCK=0
CONFIG_FB_OMAP2_DSS_SLEEP_AFTER_VENC_RESET=y
Please note. The display works properly with my older kernel ver.5.4.
Please help.
Thx,
Kiran.
Below is comparison snap showing some differences (Left: Kernel 5.10, Right Kernel 5.4 ) between lcd0 in dts file. Even the compatible strings are different. I had tried copying over older dts section for lcd0 but didn't worked out.
Attaching logs and dts files for reference.
