Hi , I was trying to run the hello world example on GEM5 whose source file was compiled using:
**arm-linux-gnueabi-gcc -mtune=cortex-m4 -mcpu=cortex-m4 --static -march=armv7e-m -mthumb hello.c -o hello_32** And when i try to run it on GEM5, i get the following: **./build/ARM/gem5.opt ./configs/example/arm/starter_se.py --cpu minor --cpu-freq 0.2GHz ./tests/hello_32** gem5 Simulator System. http://gem5.org gem5 is copyrighted software; use the --copyright option for details. gem5 version 21.2.1.0 gem5 compiled May 13 2022 14:15:20 gem5 started May 14 2022 17:53:42 gem5 executing on eden, pid 46050 command line: ./build/ARM/gem5.opt ./configs/example/arm/starter_se.py --cpu minor --cpu-freq 0.2GHz ./tests/hello_32 info: 1. command and arguments: \['./tests/hello_32'\] Global frequency set at 1000000000000 ticks per second warn: No dot file generated.
