How to enable optee for imx8mm with LPDDR size 4G

[shinningball]

Hi experts:

       I've worked on imx8m mini, and optee works fine on LPDDR 2GB version. But hangs on the kernel for 4GB version. Does any one have encounter the same issue and resolve it? Thanks.

Hi Igor,

Can you please share the email details with the community?

Hi igor:

     Sorry to mention that the branch I worked with is 5.4.47.2.2.0, so the patch about tzasc.c is not in the current imx-optee-os source code, could you update the patches about this issue for branch 5.4.47.2.2.0. Also the content of chapter 5 Configuring optee in the document Linux iMX Porting Guide is out of date.

Many thanks.
