IMX8M-EVK & NXP OLED

Hi,

 

We recently purchased the NXP MIPI-DSI OLED for use with our IMX8M-EVK board but we're unable to get the panel to display anything.

 

I have made sure the correct device tree is used (I've both explicitly set this in the configs & set on boot via u-boot cmd), I'm using the fsl-imx8mq-evk-dcss-rm67191.dts tree.

 

This is the error I see in the bootlogs.

 

[1.054926] imx-drm display-subsystem: bound imx-dcss-crtc.0 (ops dcss_crtc_ops)
[1.062412] nwl_dsi-imx mipi_dsi@30A00000: Using DCSS as input source
[1.069107] imx-drm display-subsystem: failed to bind mipi_dsi@30A00000 (ops imx_nwl_dsi_component_ops): -19
[1.079031] imx-drm display-subsystem: master bind failed: -19

 

Any help with this would be greatly appreciated.

 

Kind regards

Oli
