FAT32格式失败

我用CY7C68024和两个存储器NAND128W3A2（从ST）制作了一个板。它是根据柏树开发工具包设计的。当我运行NX2LP程序员实用工具时，我可以设置内存类型等，但是如果它试图创建一个FAT芯片，它会立即停止，并显示“FAT32格式失败”的消息。我不知道这个问题我该怎么办。非常感谢。

          I made a board with CY7C68024 and two memories NAND128W3A2 (from ST). It's designed according to a developement kit from Cypress. When I run a NX2LP Programmer Utility I can set type of memories etc. but if it try to create a FAT on chip, it's stopped immediately and show message "FAT32 formatting failed". I don't know what can I do whit this problem.   
Thank you very much.
