1.. _ColdFire-System-emulator: 2 3ColdFire System emulator 4------------------------ 5 6Use the executable ``qemu-system-m68k`` to simulate a ColdFire machine. 7The emulator is able to boot a uClinux kernel. 8 9The M5208EVB emulation includes the following devices: 10 11- MCF5208 ColdFire V2 Microprocessor (ISA A+ with EMAC). 12 13- Three Two on-chip UARTs. 14 15- Fast Ethernet Controller (FEC) 16 17The AN5206 emulation includes the following devices: 18 19- MCF5206 ColdFire V2 Microprocessor. 20 21- Two on-chip UARTs. 22 23The following options are specific to the ColdFire emulation: 24 25``-semihosting`` 26 Enable semihosting syscall emulation. 27 28 On M68K this implements the \"ColdFire GDB\" interface used by 29 libgloss. 30 31 Note that this allows guest direct access to the host filesystem, so 32 should only be used with trusted guest OS. 33
