Hello,
As you can see in the error("fatal: syscall set_tid_address (#256) unimplemented"), the emulation of system call "set_tid_address" is not emulated.
You can apply this explanation in future problems with "syscall X unimplemmented".
I propose you several options:
1. Use FS mode.
2. Try to change de benchmark code to avoid this syscall.
3. Try to implement the syscall emulation.
I hope to help you.
Best regards,
Alberto.

Hi,I am trying to run tiny-dnn benchmarks (convolutional neural network benchmarks written in C++ ) in gem5 SE mode.Here are the steps I followed:1. Cross-compiled some benchmark examples using a cross compiler (built using croosstool-ng) for ARM.2. Run the executable in gem5 SE mode using following command:$ ./build/ARM/gem5.opt configs/example/se.py -c /home/iiitd/Desktop/tiny-dnn/examples/mnist/train -o /home/iiitd/Desktop/tiny-dnn/data-------------------------------------------------------------------------------Global frequency set at 1000000000000 ticks per secondwarn: DRAM device capacity (8192 Mbytes) does not match the address range assigned (512 Mbytes)0: system.remote_gdb.listener: listening for remote gdb #0 on port 7000warn: ClockedObject: More than one power state change request encountered within the same simulation tick**** REAL SIMULATION ****info: Entering event queue @ 0.
