Hello there
I am using the imx8mmini-bb development board, when I want to light up the mipi screen, load fsl-imx8mm-evk-rm67191.dtb, it prompts
[ 1.657951] imx_sec_dsim_drv 32e10000.mipi_dsi: wait payload tx done time out
[ 1.657960] panel-raydium-rm67191 32e10000.mipi_dsi.0: [drm:rad_panel_enable] *ERROR* Failed to set tear scanline (-16)
[ 1.657965] imx_sec_dsim_drv 32e10000.mipi_dsi: panel enable failed: -16

Why, what should I do?

Hello,

How are you setting the device tree for the MIPI-PANEL?

To change it. Please make it as follows:

u-boot -> env edit fdt_file

u-boot -> fdt_file:fsl-imx8mq-evk-dcss-rm67191.dtb # or fsl-imx8mq-evk-dcss-rm67191-b3.dtb, that the depends of the revision of your board.

u-boot -> saveenv

u-boot -> boot

Whit that configuration you should be able to use the MIPI-Panel.

Hope it could solve your problem.

Best regards,

Diego.
