Re: [Qemu-devel] Using QEMU for embedded systems

[Waqqas Jabbar]

The bare basic needed for an embedded system is to
emulate the following devices
1) one serial port
2) flash
3) ram

an aditional network card is also good (for tftp and
nfs mounted kernel and/or root filesystem). The main
difference between different board is the address
where these devices are mapped. 

The only thing missing in qemu is the flash device
support. how did u handled it? 

The size and memory location of these devices can be
set thru a configuration file or as command-line
parameter.

Did the new instructions that you added were required
to boot linux on your board or was it required by the
software you are developing on that board?
