About MIPI-DSI maximum vertical setting for i.MX8M-Nano

[george]

Dear All,

Now our customers are choosing the I.MX-8M-Nano for their products.

However, the LCDs they want to use have an unusual aspect ratio as follows.

The outline specification of i.MX8M-Nano is described as 1080P.

Does the i.MX8M-Nano have the ability to drive the LCD with the above specifications with MIPI-DSI?

If we want to try it, please tell me where to change the BSP.

Best Regards,

George

for all of panel driver, you can find:

Hello @joanxie,

I checked panel-raydium-rm67191.c you taught me.
From Source Code, this LCD looks portrait-type and has more than the number of Virtical lines we need.

But then I was confused by the documentation for MX8-DSI-OLED1(AN12189).
Because the OLED is described as 1920*1080.

Is this OLED (with RM67191) actually H:1080*V:1920?
If so, I could tell the customer that the i.MX 8MN can handle H:480*V:1280 LCD

Best Regards,
George

Hello @joanxie,

We can refer to the driver source code and device tree you have provided.

Is there any information about availability for 1280 lines?
