针对1:在kernel config中,Kernel Hacking这个大项中,enable跟lock/mutex相关的config,比如CONFIG_DEBUG_MUTEX,以及CONFIG_DETECT_HUNG_TASKS, 这样当死锁发生时,稍微等待一段时间(默认120秒),kernel就会检测到死锁,同时打印出调用栈。在kernel hacking里面,包含了大量的有利于调试的config,可以一项一项都看一遍,总有一款...

I'm getting kernel panics while running linux application on my custom hardware design(iMAX6Q processor based). But another custom hardware which is similar to this can run this linux application without any problem. I did the memory calibration and stress app test for this boa...
how to use for Linux kernel debug Michi Yama Guru10030points Hi, I have one question regarding XDS560. I heard that the I-cache/D-cache must be disabled when debugging the kernel of Linux. If you stop the execution of the code at brreakpoint without the cache d...
Recently, I've encounterd a kernel oops on a embedded linux system based on I.MX6ULL and 5.10.9 version of kernel. This issue has bothered me for
如果你已经有了一段代码想要放到内核树里,但是需要某种形式的帮助,那么kernel-mentors项目就可以帮你的忙了。这是一个邮件列表,可以在下面找到: http://selenic.com/mailman/listinfo/kernel-mentors 在你对Linux内核代码作任何实际的改动之前,必须要了解相关的代码是如何工作的。为了达到这个目的,没有比直接读它(很...
In order to activate debug messages during the boot process, even before userspace anddebugfsexist, use the kernel's command-line parameter:dyndbg For instance, the kernelbootargscan be modified in the following ways: Mount a boot partition from theLinuxkernel console, and then update the extl...
In this section, we present three methods to debug the kernel and the user application. We first present how to add debug symbols during the compilation. Then, we present the debug serial console which is the main mechanism to get debug information during runtime. We finish this section by ...
13) Save and quit the kernel debug. 14) Now you need to turn on the TCF agent that will be active in the Linux kernel on board, and will give you access to the hardware during kernel debugging. 15) Openpetalinux-config -c rootfsinside the petalinux project directory. You should see th...
