问题 I am trying to get kgdb working with Android kernel using http://bootloader.wikidot.com/android:kgdb. I got stucked at following step: Configure kernel command line Specify ttyGS0 as the kgdboc device. Add the following into the kernel command line (possibly in BoardConfig.mk) kgdboc=ttyGS0 kgdbretry=4 The second option "kgdbretry=4" is a new parameter added to kgdboc.c. It means that if kgdb cannot find the device "ttyGS0" in early boot, it will retry once after the specified number of

问题 I am trying to do remote debugging. My GDB server runs as expected (in my case it is KGDB in kernel side). KGDB hangs up well so that GDB client can connect. I need to connect GDB client using terminal server and port number because my device is connected via terminal server in real case scenario where username and password are required to get in. Hence just doing target remote terminal-server:port is not helping to connect because there is no method to supply username and password. If I

问题 I read the description of both but I don't yet understand the difference. Can anyone help me understand the differences? set solib-absolute-prefix - Specifies the local directory that contains copies of target libraries in the corresponding subdirectories. This option is useful when debugging with gdbserver. . set solib-search-path command - Specifies directories where GDB will search for shared libraries with symbols. This option is useful when debugging with gdbserver. Thanks. 回答1: The

This is a work-around if the USB device is not immediately initialized during system boot. Could

I'm trying to do kernel debugging for my Nexus One, and have been following instructions from http://bootloader.wikidot.com/android:kgdb . I was wondering if someone has actually got this to work? And has anyone done a more up to date solution for using KGDB to debug the kernel? I found this post when I was looking for information of KGDB on Android so, despite it being a few years old, I thought it worth posting a link to some work I did to get this up and running on the Nexus 6. http://www.contextis.com/resources/blog/kgdb-android-debugging-kernel-boss/ I hope this helps anyone else looking

问题 Im using ARMv7 as a target machine. I have compiled the Linux source 2.6.34.13 for target. Target is connected with Host(Linux Development machine) through serial port using minicom. Target is loaded with new kernel and KGDB is enabled in command prompt. $ echo ttyAMA0 > /sys/module/kgdboc/parameters/kgdboc $ echo g > /proc/sysrq-trigger Entering KGDB... message is displayed and waits for commands. In Host side , $arm-none-linux-gnueabi-gdb vmlinux gdb > set remotebaud 115200 gdb > set debug
