  Nothing recovered
  Too much blocks erased
  And look like controller had dead cache memory
  Data was writed with additional changed bits

常见问题解答

IS902主控芯片支持哪些闪存颗粒的布局模式？

根据文章内容，IS902主控支持多种闪存布局，例如IS802B 2c 68 04 46对应4×1布局，以及89 68 04 46对应4×4布局。不同布局模式会影响输入顺序、数据合并方式等参数，恢复时需根据芯片ID和实际颗粒结构选择正确配置。

在IS902数据恢复中，Block和Page大小如何确定？

文章提到两种典型参数：一种Block大小为0x4000，Page大小为0x4000，Bank空间0x4000；另一种Block大小为0x1000，Page同样为0x4000。具体数值需通过扫描芯片识别，并参考布局中的Join by Byte/Page Parts设置来正确组装数据。

IS902出现未知文件系统时如何处理？

当扫描结果提示’Unknown file system’时，说明当前参数组合无法正确解析数据。此时应检查芯片ID（如2c 68 04 46或89 68 04 46）对应的布局，尝试调整Mix Input Order、Join by Parts等参数，或参考类似型号的配置，必要时使用Serg工具进行进一步扫描验证。
