Hi dkryder
Thank you for answering.

I changed the DSI resolution with compile / de-compile.


Changed from default value as follows.
Then, a kernel panic will now occur on startup.

<default>
---------------------------------------------
2166             lcd_x = <0x400>;
2167             lcd_y = <0x258>;
---------------------------------------------
<modify>
---------------------------------------------
2166             lcd_x = <0x216>;
2167             lcd_y = <0x4B0>;
---------------------------------------------

However, setting it to half of the default value starts normally.

<default>
---------------------------------------------
2166             lcd_x = <0x400>;
2167             lcd_y = <0x258>;
---------------------------------------------
<modify>
---------------------------------------------
2166             lcd_x = <0x200>;
2167             lcd_y = <0x12C>;
---------------------------------------------

Is there a limit to the setting value of DSI?

Thank you.
