Change video source in Uboot config

wdunkley — Thu, 08 Oct 2020 21:03:12 GMT

I'm currently designing around Imx8mm however I'm struggling to find information about how to change the default source video source from HDMI to (for this case) Mx8_dsi_oled1. I'm compiling Windows IOT, however, that shouldn't matter for these lower-level drivers. While looking through the uboot readme I came across a couple of configs for video but nothing very helpful, I also came across a config "CONFIG_IMX_MIPI_DSI_BRIDGE" but without and documentation I don't know enough about it other than to add it into the config file and try it out. Any help on this along with a place to find more information about configuring different hardware settings would be so appreciated. Thanks Everyone

Will

Hi wdunkley

one can look at documentation, in particular sect.14.1.1 U-Boot Configuration Options

Windows 10 IoT User Guide on link

https://www.nxp.com/design/software/embedded-software/i-mx-software/windows-10-iot-core-for-i-mx-applications-processors:IMXWIN10IOT?tab=In-Depth_Tab

uboot sources:

uboot/include/configs/imx8mm_evk.h : CONFIG_VIDEO

uboot-imx/tree/board/freescale/imx8mm_evk/imx8mm_evk.c

Best regards
