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.
