enable dsi driver with imx8mp

DEEPIKA19 — Thu, 11 Aug 2022 14:01:44 GMT

Hi team,

I am trying to enable dsi display with imx8mp.

As suggested in the forum, i tried to add st7701 with the device tree as below

&lcdif1 {
status = "okay";
};

&mipi_dsi {
status = "okay";
panel@0 {
compatible = "techstar,ts8550b";
reg = <0>;
dsi-lanes = <2>;
};
};

I tried to boot the board and i am getting the following error.

[ 6.813406] imx-drm display-subsystem: bound imx-lcdifv3-crtc.0 (ops lcdifv3_crtc_ops)
[ 6.979483] imx-drm display-subsystem: bound imx-lcdifv3-crtc.1 (ops lcdifv3_crtc_ops)

Hi @DEEPIKA19

The core log: 'unsupported dsi mode', you need check your panel driver about dsi mode.

Thanks for your reply @Zhiming_Liu

I tried to change the dsi mode in the panel driver and the error is resolved.

But nothing on the dsi.

While checking the logs, I observed the below error related to dsi

imx_sec_dsim_drv 32e60000.mipi_dsi: wait payload tx done time out

Please could you suggest a way to debug the issue.

Thanks in advance
