Using
Emulators
SeptemberOS is tested and used on QEMU system emulator on all platform
that QEMU supports. Using an emulator saves a lot of initial debugging
time due to very fast boot loads and emulator's options.
QEMU also contains a GDB stub, thus creating a unique offer of
development and debugging on a single host.
SeptemberOS was also tested and used on VmWare.
Things to remember when working with emulators:
- Most emulators (in particular, QEMU and VmWare)
are not cycle-accurate. They may give overall functionality and
performance picture, but
concrete (especially short) sequences of events may take different time
(and different relative to each other time) than they would take on a
real platform.
- Not cycle-accurate emulators don't emulate
simultaneous events
Below you may find setups for QEMU and VmWare emulators that were used
for testing SeptemberOS.

Remember to copy the specified image from build result directory
("image/") to the emulation setup directory. If you send emulator's
serial output to a file you may want to delete that file before every
new emulator session.
