Hi Rabab, Sorry for the delay in my response.
To me this looks like workload automation is not able to match the prompt in your simulated system. WA sends commands to the system terminal in order to interact with the simulated system. As part of this, it must understand what a prompt looks like such that it is able to send the next command at the correct time, as well as parsing the output of the previous command. The last log message you pasted below originates from this line in WA: https://github.com/ARM-software/workload-automation/blob/master/wlauto/common/gem5/device.py#L258 Would you be able to tell me what the prompt for your system looks like? Does your system require you to log in prior to executing commands? I think that the best course of action at this point would be to open an issue on the WA github page: https://github.com/ARM-software/workload-automation/issues Could you please attach your wa_output/run.log, your agenda as well as the wa_output/gem5/system.terminal to the issue please?
