Q1. 编译完成后,ELF解析的bss数值3372,并不等于bss_end - bss_start,而是等于bss_end - sstack。 Step 1. 在RT-ThreadStudio中创建一个基于4.0.5和STM32L431RCTx的工程。 编译完成后,得到的输出结果是 arm-none-eabi-size --format=berkeley "rtthread.elf" text data bss dec hex filename 53632 1816...
清除bss 段 上面代码中的_bss_start,是: .globl _bss_start_bss_start:.word __bss_start而_bss_end,是:.globl _bss_end_bss_end:.word _end对应的,__bss_start和_end,都在前面提到过的那个链接脚本里面:u-boot-1.1.6_20100601\opt\EmbedSky\u-boot-1.1.6\board\EmbedSky\u-boot.lds中的:__bss...
__bss_start 在 u-boot.lds 定义 至于uboot.lds 和__bss_start怎么定义就要了解 链接脚本的相关知识了
这里，实际上句（1）是在bss段的起始地址处定义了一个int类型的全局变量__bss_start。虽然，bss段的...
