这边文章讲述的是坏快检测功能

思路:

1.第一次烧录固件会实现跳坏块,但是后续使用会导致坏块的产生;

于是我在uboot环境变量添加了两个变量来控制坏快

lb_badnum = //坏块个数

lb_badoff = //坏块所在位置

2.第一次开机会根据lb_badnum是否存在判断,如果不存在则保存上面坏块信息,跳过坏块功能

3.第二次开机之后会获取环境变量lb_badnum和lb_badoff;

3.1.然后检测实际坏块数,进行对比,如果有新增坏块, 则判断新坏块产生的所在分区;

3.2.然后判断所在分区坏块大小加上固件大小后是否超出划分的分区空间;

3.3.执行对应的分区还原;
