Hello,
due to sloppy documentation I need help from mailing-list, again.
I want to access Hardware (HW) from a L4re-App.
Actually, I already did this with the old IO-config style. I described the HW in *.devs and *.io file and then I was accessing the HW, directly with l4io_request_iomem(ADDR, 4, L4IO_MEM_NONCACHED, &baseaddr);
With the new functions() style IO-config anything is described in a single *.io, right?
Well, mine looks like this:
-- vim:ft=lua: Io.Dt.add_children(Io.system_bus(), function() RNG = Io.Hw.Device(function() compatible = {"dev-rng,mmio", "dev-rng"}; Property.hid = "dev-rng, RNG_0"; Resource.regs = Io.Res.mmio(0x43c00000, 0x43c0ffff); end); end);
Io.add_vbusses { rng_server = Io.Vi.System_bus(function () dev = wrap(Io.system_bus():match("RNG")); end); }
(Not sure if I really need 'compatible and 'Property.hid', here..?)
Anyway, all I see is output from IO but, no other L4Re-App seems to start. IO | Io service IO | Ready. Waiting for request.
Anybody already spot the fault?
May I still use l4io_request_iomem() to access the HW or, did things change here, too?
Thanks,
