Hi, expert Regarding the use of optee dynamic shared memory, we have encountered some problems that cannot be solved recently. Debug log is as follows: REE OS kenrel->TEE SPMC (FFA_MEM_SHARE) WARNING: SPM(5): 0x84000073 0x50 0x50 0x0 0x0 0x0 0x0 0x0 VERBOSE: hafnium ffa_handler func:0x84000073 VERBOSE: hafnium allow for one memory region to be shared to the TEE.

Can anyone figure out what the problem is and give some debugging directions? Thanks! regards, yuye
