常见问题解答
AU6990芯片在数据恢复中有什么特点？
根据文章内容，AU6990芯片的数据恢复涉及特定的布局参数，如块大小（Block Size）为0x2000或0x4000，页大小（Page）对应0x2000或0x4000，以及不同的输入顺序（Mix Input Order）设置。这些参数直接影响恢复过程，需要根据芯片的物理结构进行精确配置，才能实现完美恢复效果。
AU6990芯片的1×1和2×1布局有什么区别？
文章提到AU6990芯片支持1×1和2×1两种布局。1×1布局下，块大小为0x200000，页大小为0x2000，输入顺序为0；而2×1布局下，块大小增大到0x400000，页大小为0x4000，输入顺序为1/0，并采用按字节拼接（Join by Byte Parts）方式，数据部分为false。这些差异影响恢复时的地址映射和数据处理方式。
如何根据AU6990芯片参数进行扫描和恢复？
根据文章，恢复AU6990芯片时需要设置正确的块对（Block Pair）、块大小、页大小、银行空间（Bank Space）等参数，然后使用扫描功能查找银行大小。例如，1×1布局下银行空间为0x400，2×1布局下同样为0x400。操作者需结合芯片ID（如2c 88 04 4b）和具体布局，通过工具如Flash Extractor进行扫描和恢复，以获得完美结果。
