Hi, David Turner , thanks.
It's my kernel driver for ttyVSP0 make kernel panic.Now i can make a
MT or MO call, and receive SMS.
BUT, there are another three questions, please give me some advice:
(1) If a MT call happening , no prompt in android UI.
If a new message received , no prompt in android UI.
How to make prompt automaticly in my android UI ? whether do i need
modify some JAVA code?
(2) If i get a MT call, i can't get voice. How can i get voice?
(3) I can't send message, logcat :
