針對飛凌6410中動態卸載驅動時候出現rmmod: chdir(/lib/modules): No such file or directory怎么解決？

1.在文件系統目錄中創建 /lib/modules/3.0.1這個空目錄

2.查看/sbin中是否有rmmod，如果沒有，靜態編譯如下代碼，將生成的rmmod放入/sbin中

?

#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <fcntl.h>
#include <string.h>
#include <errno.h>

int main(int argc, char *argv[])
{
??? const char *modname = argv[1];
??? int ret = -1;
??? int maxtry = 10;

??? while (maxtry-- > 0) {
??????? ret = delete_module(modname, O_NONBLOCK | O_EXCL);//系統調用sys_delete_module

??????? if (ret < 0 && errno == EAGAIN)
??????????? usleep(500000);
??????? else
??????????? break;
??? }

??? if (ret != 0)
??????? printf("Unable to unload driver module %s : %s/n",modname, strerror(errno));
}
