本帖最后由 anwafs 于 2020-3-12 17:14 编辑

1 设置core路径
echo "/home/core/core-%e-%p-%t" > /proc/sys/kernel/core_pattern\n

2 启动gdb,根据不同的编译器：
arm-hisiv500-linux-uclibcgnueabi-gdb

3 设置动态库路径
set sysroot /share/10047/lib/arm-hisiv500
set solib-search-path /share/10047/lib/arm-hisiv500

4 装载dora
file dora

5 运行core 文件
core-file ./core-dora-xxxx

6 bt
7 info thread
8 thread xxx


6、 objdum和addr2line
arm-hisiv500-linux-uclibcgnueabi-objdump -D xx.a > /home/XX

arm-hisiv500-linux-uclibcgnueabi-addr2line -e xx 0xddd


7、输入f 1，进入函数
输入p 变量名，打印变量
