Hi @yxjiang ,

Which board are you using? I see that you said you are using the imx95-15x15-evk board, but in the log I see "imx95-19x19-lpddr5-evk log in", are you uisng this board X-IMX95LP5EVK-15?

For the MIPI display, the screen is you buy from our NXP, or other company , here you porting it to NXP board? Thanks.

Wish you have a nice day

Best Regards

Rita

Hi @Rita_Wang
1.I am using the imx95-15x15-evk.
2.Does the filename (imx95-19x19-lpddr5-evk) in the file system /etc/hostname have an impact?

You can see that they are two difference boards, you can see board dts file are seperate:

linux-imx/arch/arm64/boot/dts/freescale at lf-6.12.y · nxp-imx/linux-imx · GitHub

Here for the screen it is supply with the EVK board, or you need to porting to the  imx95-15x15-evk?
