I've not had the problems I'm seeing discussed on this list but then I used
the MokoMakefile approach. One thing to note -- the OpenMoko build system
comes with its own version of QEMU, with changes specific to the Neo1973.
Running a stock QEMU outside the build environment will probably limit what
you can do, in particular it lacks the virtual Neo1973 hardware they added.
Re a few of the troubles,
- Giles, I didn't have to modify any .h files to make it work, nor did I
see any problems with the 8ma power you saw.
- Lars, Yes, the onscreen keyboard does work, as in the GUI keyboard you
click on with the mouse. I click in the upper-left box (white area,
not icon) and the onscreen keyboard comes up in my QEMU image.
- out of the box, it does not let you type into it using your desktop
keyboard but you can add -usbdevice keyboard to make it work
- I can say that the ability to 'ssh' into the QEMU does work here,
but it requires a few steps in the QEMU monitor each time you use
it re usb_add gadget:1 that cannot be automated.
- To network into the QEMU image you must have gadget support in your
host kernel. The Neo1973 docs talk about having a /dev/gadget file,
for example with a gadgetfs mounted on it. I have to create it by
hand each time I boot, as the udev system doesn't keep it around
on my Gentoo system. I checked the source and you cannot move it
elsewhere - the path is hardcoded.
I hopes this helps,
