TEEC_InvokeCommand(forward) failed when running fl_tee_layerwise.sh on HiKey 960 about ppfl HOT 4 OPEN

Hi @HenryHu2000 , the TEEC_InvokeCommand(forward) failed 0xffff3024 origin 0x3 error is typically caused by the secure memory limits. When one layer's weight matrix is created during the forward pass, out-of-memory happens. But I found in your test, the layer is quite small, and seems not large enough to trigger this problem?

The cfg files you mentioned are not in tz_datasets/cfg, but server_side_sgx/cfg. You may try run again with these cfg files inside

Hi @mofanv, thanks for your reply. Yes, I used the cfg files in server_side_sgx/cfg but was still getting these errors. Without these cfg files, fl_tee_layerwise.sh doesn't run.

I followed the exactly same configuration as in the paper. I tried the following 3 configurations on fl_tee_layerwise.sh but none of them worked:

• Device=HiKey 960, TA_STACK_SIZE=1 * 1024 * 1024, TA_DATA_SIZE=10 * 1024 * 1024 (default settings from the repo)
• Device=HiKey 960, TA_STACK_SIZE=1 * 1024 * 1024, TA_DATA_SIZE=12 * 1024 * 1024
• Device=Raspberry Pi 3, TA_STACK_SIZE=1 * 1024 * 1024, TA_DATA_SIZE=6 * 1024 * 1024

However, other scripts like fl_tee_standard_noss.sh and fl_tee_standard_ss.sh do run correctly. It seems that changing the flag -ss 2 to -ss 1 also avoids the error, but I guess it breaks the intended purpose.
