  1. 环境：

stm32F103 512K内部flash
裸机程序测试

  1. 问题：
    当分区数据写满后，触发gc回收flash空间时，此时按复位重启，重启后，程序会卡到触发gc回收flash空间的过程中flash全部擦除后，再烧写程序可以恢复正常

  2. 日志如下：

我解决了，发现是Flash的擦除问题，没擦除成功，导致一直触发GC

你先确保 FAL 对你Flash的擦除是成功，我遇到的问题是我擦除 Flash 失败，但是我返回了擦除成功的结果的 GC，导致出现了 GC 一直触发的问题。你最好检查一下你自己实现的 FAL 的 flash 操作是不是都正确的。

分析了下源码的流程：
do_gc() -> format_sector() -> _fdb_flash_erase() -> fal_partition_erase() -> ops.erase
在这个过程中do_gc()调用ormat_sector()时，没有判断返回值。
现在我的环境复现不了该问题了，也不知道是不是这个原因了
