Virt,gic-version=max,secure=true,virtualization=true -cpu cortex-a72Īnd here is the gdb run result. Now I run qemu baremetal program to debug the code. So I ran aarch64-none-elf-gcc -g test.c -specs=rdimon.specs I learned in the past the -specs=rdimon.specs compile options removes this errors.
I get undefined reference errors for _exit _sbrk _write _close _lseek _read _fstat and _isatty. To make long story short, I want to run arm64 baremetal hello world program on qemu. While trying to debug an inline assembly code, I met with another basic problem. Often a question leads me into another question.
