CE would arbitrarily pull LOW on banks with NR
CE0 read green, CE1-7 read red
Solution manually pull CE0-7 HIGH/LOW with v3.3/GND
on respective banks then CE1-7 read 70% green with RR

常见问题解答
Monolith USB 20-82-00515-5的闪存参数是什么？
该Monolith USB型号为20-82-00515-5，采用1×1布局，ID为45 3e 99 b3。其闪存配置包括Xor C634、16_2混合输入顺序、慢速扇区大小0x1000，以及组装器扇区编号。这些参数用于数据恢复时正确解析闪存芯片的物理结构，帮助提取原始数据。
EN3257主控的USB闪存如何配置Xor和块参数？
EN3257主控的USB闪存（ID 2c 88 08 5f）使用Xor 101d_256，混合输入顺序为0，块配对模式，块大小0x300000，页大小0x2000。组装器块编号和块大小0x600000用于映射物理块，更新大小0x4000且启用更新，这些配置对恢复损坏的USB数据至关重要。
如何解读USB闪存扫描中的Bank和更新参数？
扫描参数中的Banks从00到04，每个Bank包含0x000至0x0ff的块范围，用于标识闪存内部的物理区域。更新大小0x4000和更新启用true表示系统支持部分块更新，这有助于在数据恢复时处理磨损均衡或坏块，提高数据提取的完整性和准确性。
