human_face_recognition例程中录入的人脸无法储存 (AIV-605)

[CaoJu600]

人脸可以正常录入、对比、删除，但似乎没有储存到flash，重启后仍显示
I (1102) MFN: fr partition size: 131072 bytes, maxminum 62 IDs can be stored
I (1102) MFN: No face ID in flash
lcd和terminal例程都尝试过，芯片为esp32s3 n16r8，例程代码没有任何修改。
不清楚是哪里的问题，希望能帮忙找下原因，谢谢！

我又进行了进一步的测试。
在全片擦除后注册的第一个人脸可以正常储存，重启后仍能读取到。
但如果继续注册第二个人脸或者删除人脸重新注册，则所有注册的人脸(包括第一个)都无法储存，重启就会丢失，必须要再次擦除flash才能恢复。
