Dear Sir,

I am using Imx8mPlus and yocto-L5.10.35_2.0.0.

It seems that the IPU error occurs during compiler linux kernel.

I turn on the config in kernel as below:

CONFIG_MXC_IPU=y
CONFIG_MXC_IPU_V3=y

and apply below patch:

However, It seems that IPU error occurs as below .

Q1.

How can we resolve this error?

Hello Kevin,

 

Those driver are for the MX6, since MX8Mplus don't have IPU.
