Richard Cooper has submitted this change. ( https://gem5-review.googlesource.com/c/public/gem5/+/69688?usp=email ) Change subject: configs: Add --exit-on-uart-eot flag to Arm baremetal.py config ...................................................................... configs: Add --exit-on-uart-eot flag to Arm baremetal.py config Many benchmarks signal their termination by writing an EOT character to the UART. This change adds an option to the Arm `baremetal.py` example script to exit the simulation when an EOT character is detected on any of the UARTs.
