Hi,
As I mailed before I also have a non working C115, but I have 3 working so I have something to compare. I suspect a hardware problem on my side, but I tried your tips
Maybe your machine is too slow, but you could try this: http://lists.osmocom.org/pipermail/baseband-devel/2011-February/001407.html I'm not sure if the patch still applies correctly though.
No it doesn't but I compiled it and it did not help me.
If that doesn't work, here's another thing to try: http://lists.osmocom.org/pipermail/baseband-devel/2011-January/001053.html
Tried that too without result.
I also confirmed by breaking the TX line to the phone (from the PC) that this error (FTMTOOL error) then also happens. So it can also be caused by a faulty cable, faulty connector or blown UART pin on the Calypso.
Best regards,
Job
