Intro
First time I tried debugging Qemu, I had some problems with signals, serials, etc.Debug
configure
Configure qemu to use debug./configure --enable-debug --enable-fdt --target-list=arm-softmmu
signals
add the following lines to your .gdbinit:handle SIGUSR1 SIGUSR2 noprint nostop
Qemu uses those signals for timeout and internal stuff, we don't need to track them
serials
Then I had problems with serial lines in gdb, Reading the serial worked well but I couldn't write to it...My workaround is to call:
socat -d -d pty pty
You get two pty.
Call screen on the second one to be able to write to the serial port.
