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 […]
Instructions to compile and run the U-Boot bootloader inside a QEMU emulation of an ARM platform.
Create a simple "Hello world" program that prints on the serial port of an emulated ARM system, using the CodeSourcery gcc toolchain and the QEMU emulator of the Versatile board.
Serial ports are not very useful for the end-user, but they are very important for administration of headless (without monitor) servers and for embedded device development. For example, if you are designing a chip that contains a micro-processor with a serial port (UART) to communicate with an external control (such as a graphical tool running […]
