Hi list, I've been trying to setup a debug environment for linux kernel(v3.4,Android,ARM) with kgdb. It worked fine untill I tried to use it to debug a module. Under the instruction from LDD, I add module debug info in gdb with command: add-symbol-file test-module.ko address LDD uses `cat /sys/module/test-module/sections/.text` to get the address where the module has been loaded. However, I got: 0x00000000 When I use `lsmod`, I got: test-module 15278 0 - Live 0x00000000 (O) Why nothing but 0x00000000 ?? So I have to do some research in kernel/module.c, and find out that struct module -> module_core = 0xbf000000. But when I try these in gdb: add-symbol-file test-module.ko 0xbf000000 break one_of_my_function I got: Cannot access memory at address 0xbf002350 :( Could somebody help? All the best! Freeman Zhang
