I found that the latter one seams to be somewhat _incomplete_, that is it doesn't support handles for _reset_ and _wake/sleep_ gpio-pin configuration. Further, this makes connecting the mrf24j40ma to the RasPi pinout inconvenient (IMHO). On the other hand the atmel driver (at86rf230)[1] does support these functions, so I'd like to _port_ the reset and sleep functionality into the mrf24j40 driver[2]. > Yes, hard-reset functionality would be nice. > > Remember the wake/sleep functionalty is limited only, if the subsystem doesn't use the > transceiver then it will go into sleep mode.

I'm willing to work on that and implement these extension, maybe also restructure/clean up the driver code a little bit in this process. > ok.

I've had some plans too to extend the driver. Maybe we could collaborate with this since we seem to have the same ideas. As Alexander said, I've got the reset functionality on my to-do list, but haven't found time to implement it yet. I also had the idea to implement some sanity checks in the interrupt code. Furthermore it might be nice to have some kind of check in the hw_init code to probe the device somehow and error if the radio does not respond (correctly). It would be great if you have time to implement some of these functions. When I find the time to start working on these things I'll notify you so we don't do the same work twice :) Koen -- To unsubscribe from this list: send the line "unsubscribe linux-wpan" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
