QEMU is able to emulate ARM systems with multiple serial ports, for example the Versatile PB. It has the ability to direct them to many types of host resources such as standard I/O, a pseudo-terminal or a telnet port. I started from my hello world example for bare-metal ARM programs to control three different serial […]

QEMU is able to emulate ARM architectures with many details. One thing that the qemu-system-arm program implements is the Angel interface, that enables semihosting. Semihosting involves two machines: a target (the embedded device), and a host (such as a PC) that is connected to the target through a debug interface. An embedded program running in […]
