GDBDebugging¶

Here are some notes on debugging with gdb while rebasing replicant changes on top of the last cyanogenmod.

Command line wifi(in case no GUI is available)¶

adb shell
mkdir /data/ctrl

/sdcard/wifi/wpa.conf:

ctrl_interface=DIR=/data/ctrl
network={
#your settings go here
}

adb shell
wpa_supplicant -iwlan0 -Dnl80211 -c/sdcard/wifi/wpa.conf

adb shell
dhcpcd wlan0

GDB debugging(requires a network connection)¶

adb shell
while true;do gdbserver 192.168.20.132:8022 --attach $(pidof system_server);done

. build/envsetup.sh
lunch cm_maguro-eng
