As dmesg -c will also return the dmesg ring buffer contents before clearing it, it's probably the best way to do it, unless you maybe want to also be able to look at it manually... > > The usb cable is connected _all_ the time, right?

However, both the arduino controller and the detection code was done by himself, and I haven't seen him on IRC in a long time. > > I still don't understand very well how are you determining the state of the > Ipod.

We're basically looking for the ipod to either connect and immediately disconnect again (crash), or to connect but stop responding to commands after some time (freeze), or to connect and fully enumerate (works).

My nanotron contained a light sensor because I thought that we might need it back when building the hardware, but then found a way to do the whole detection via USB (even though I was using the platform independent approach to detect its state, by just checking whether we can access the ipods drive some seconds after it should have finished booting, and holding the disk mode combo during that time to catch it in disk mode (recognized via timing) if it crashes). I don't think anyone has ever actually used a light sensor for the state detection :-) > > Do you have those timing specs for the 3g nano? Tucenaber probably has them, but I don't think he put them into the wiki. > > Regards > Stefan _______________________________________________ Linux4nano-dev mailing list Linux4nano-dev@gna.org https://mail.gna.org/listinfo/linux4nano-dev http://www.linux4nano.org
