1. pmap指令查看指定进程中的内存分布。该指令需要在busybox中开启
pmap -x 111
2.应用与so需要执行strip操作#xff0c;可以减小存储空间的大小
mips-linux-gnu-strip libsysutils.so
3.nm指令和file指令可以查…最近在调试T20的内存使用的指令在此记录一下
1. pmap指令查看指定进程中的内存分布。该指令需要在busybox中开启

2.应用与so需要执行strip操作可以减小存储空间的大小
mips-linux-gnu-strip libsysutils.so
3.nm指令和file指令可以查看应用和so是否为strip的
nm libzbar.so.0.2.0
nm: libzbar.so.0.2.0: no symbols file libzbar.so.0.2.0
libzbar.so.0.2.0: ELF 32-bit LSB shared object, MIPS, MIPS32 rel2 version 1 (SYSV), dynamically linked, stripped 4.mips-linux-gnu-readelf可以查看so的编译依赖的库文件
mips-linux-gnu-readelf -d libzbar.so.0.2.0
输出如下
