我创建了一个内存链接脚本,并将其保存为memory.ld在eclipse ide中: Project:属性:gcc链接器:miscellaneous:我添加了-M-T memory.ld
memory.ld:
memory.ld:
MEMORY
{
ram (rw) : ORIGIN = 0x4000000 , LENGTH = 2M
}
SECTIONS
{
RAM : { *(.myvarloc)
} > ram }
在我的 C 程序中:我进行了如下全局声明:
__attribute__ ((section(".myvarloc")))
uint8 measurements [30];
错误:
/usr/bin/ld: FEBRUARY section `.text' will not fit in region `ram'
/usr/bin/ld: region `ram' overflowed by 20018 bytes

溢出有关,而不是.myvarloc
