1、用trace32。trace32无疑是强大的，几乎可以做任何debug的事情，有高通代码的兄弟可以在\AMSS\products\76XX\tools\debug目录下找到smemlog.cmm和smem_log.pl这两个文件，可以dump出log.

2、没有trace32的兄弟也不要灰心，google为我们提供了强大的adb工具。命令如下：

adb shell

mkdir /data/debug

mount -t debugfs debugfs /data/debug

cd /data/debug/smem_log

cat dump_sym

可以给大家看一下抓下来的部分log:
