Hi Folks,
I am trying to display a splash image from u-boot on the Phytec's
phyBOARD Sargas STM32MP157 evaluation board.
https://www.phytec.de/en/produkte/single-board-computer/phyboard-sargas-stm32mp1/
https://www.phytec.de/en/cdocuments/?doc=d4PmEQ
I feel like I tried everything possible including throwing runes and
bones :-) but to no avail. So maybe someone here could help. Here are
more details and description of what I was trying.
I am using the same u-boot (version and set of patches) as provided by
Yocto BSP (I am building with Buildroot but it is probably not
relevant)
STM32MP> version
U-Boot 2020.01-stm32mp-r2.1 (Jun 24 2021 - 13:30:02 +0200)
arm-none-linux-gnueabihf-gcc (GNU Toolchain for the A-profile
Architecture 10.2-2020.11 (arm-10.16)) 10.2.1 20201103
GNU ld (GNU Toolchain for the A-profile Architecture 10.2-2020.11
(arm-10.16)) 2.35.1.20201028
Display is DPI (i.e parallel RGB interface):
https://www.phytec.eu/fileadmin/user_upload/images/content/1.Products/SBCs/phyBOARD-Segin_i.MX_6UL/LAN-072e_1.pdf
I managed to display a splash screen from Kernel and in general, the
display works fine from user space. So I am sure that everything is
connected properly and the hardware works. Also, u-boot is using the
same DTS files as Kernel. So I assume that everything is properly
configured there. Following is the relevant part of the output from
modetest:
# modetest

Encoders:

nhsync, nvsync; type: preferred, driver
In the u-boot menuconfig I enabled all the relevant options I could
find. At least the bmp command is available. Here is the Graphics part
of the .config (I can post .config if necessary):
# Graphics support
CONFIG_DM_VIDEO=y
CONFIG_BACKLIGHT_GPIO=y
CONFIG_VIDEO_BPP8=y
CONFIG_VIDEO_BPP16=y
CONFIG_VIDEO_BPP32=y
# CONFIG_VIDEO_ANSI is not set
CONFIG_VIDEO_MIPI_DSI=y
CONFIG_CONSOLE_NORMAL=y
# CONFIG_CONSOLE_ROTATION is not set
# CONFIG_CONSOLE_TRUETYPE is not set
CONFIG_SYS_WHITE_ON_BLACK=y
# CONFIG_NO_FB_CLEAR is not set
In addition, the following defines were added to include/configs/stm32mp1.h:
#ifdef CONFIG_DM_VIDEO
#define CONFIG_VIDEO_BMP_RLE8
#define CONFIG_BMP_16BPP
#define CONFIG_BMP_24BPP
#define CONFIG_BMP_32BPP
*** Below was add by me ***
#define CONFIG_SPLASH_SCREEN
#define CONFIG_SPLASH_SCREEN_ALIGN
#define CONFIG_VIDEO_LOGO
#define CONFIG_VIDEO_BMP_LOGO
#endif
For the sake of completion, here is the output of the dm tree command:

Despite all these attempts, there is no output from u-boot on the
screen. Also, attempting to load splash image manually (using
ext4load) and display them with bmp display does not lead to anything
shown on display but also does not show any error messages.
Now I am out of ideas of what else could be done or how to find the
reason for the problem. So I would really appreciate any suggestions
from fellow u-booters :-)
Thank you,
Andrey.

Hi Andrey
+Philippe and Yannick who are the experts, please interacts directly with them.
Here is Philippe's answer:
The CONFIG_VIDEO_MIPI_DSI flag is not necessary as the panel is DPI, and so maybe this DSI configuration annoys the rest of the display chain...
Moreover, we are not using following flags so maybe it is better to try without first :-)
*** Below was add by me ***
#define CONFIG_SPLASH_SCREEN
#define CONFIG_SPLASH_SCREEN_ALIGN
#define CONFIG_VIDEO_LOGO
#define CONFIG_VIDEO_BMP_LOGO
Use the STM default bmp file as a first test (bmp rle 8). Load it from the right sdcard partition to the same address space as on default STM delivery.
Then display it using the same command as on default STM delivery.
Maybe double check your clock configuration (pixel clock), and be sure you are using the same pinctrl (a0 here) as your working kernel dt, the same panel reset gpio and panel enable gpio as in your kernel dt.
Do you have any uboot error message (you may need to enable uboot debug mode)?
You may try to add traces in the drivers/video/stm32_ltdc.c file, especially in the stm32_ltdc_probe() function...
