前段时间,调试android的时候,老刷nandflash,出现了很多坏块,导致内核和android无法启动,无耐要调试从
SD启动android,此脚本分了三个区,一个用于持载android的sys目录,一个用于挂载android的data目录,这两个都是etx4格式,另一个是fat格式,用于挂载SD卡目录,android的cache目录可以挂到其它目录下,也可以修改此脚本中
- {
- echo 212,,0x0C,-
- echo 9,68,0x83,-
- echo 77,135,0x83,-
- }
在其中加入一项,并修改相关的format_drive; format_vfat函数,脚本write_disk中的相关参数要根据U-boot中的定义来设置
