i.mx8m mini evk i2c3,mipi-csi

[grif]

I am trying to control i2c3 and mipi-csi on M4 side with i.mx8m mini evk. On the A53 side, linux (L4.19.35._1.1.0) is running. Accessing the i2c3 and mipi-csi registers on the M4 side stops. I don't know how to deal with it. (Device tree file?) Please professor.

Hi Osamu

i2c3 is already supported in SDK_EVK-MIMX8M Mini available on Welcome | MCUXpresso SDK Builder 

in folder ..driver_examples/i2c

So on below fsl-imx8mm-evk-m4.dts  i2c3 is disabled

fsl-imx8mm-evk-m4.dts\freescale\dts\boot\arm64\arch - linux-imx - i.MX Linux kernel 

For mipi-csi it is necessary to perform similar steps: disable in linux dts and add driver to SDK.

Best regards
igor
