Hi, Jens Since the optee driver has not been updated to ffa 1.1, I will first update the code with ffa 1.0.

But optee-driver in linaro-swg/linux seems to be using ffa version 1.0, which causes incorrect data reading when the driver is doing mem_share to Hafnium. I need to debug my previous code. When will optee-driver synchronize this version change?
