初始化正常，数据写入正常，读取时校验异常，读取时CRC校验失败

[syh501]

移植FlashDB-1.1.2到高拓6441平台，给了一段分区大小为32k的分区给到FlashDB管理，初始化正常，数据写入看起来也正常成功，但是读取的时候失败，跟踪了一下，好像是CRC校验失败了，没有什么头绪，还望有空了帮忙看看~ （另外，感觉好像初始化的时候，格式化了2次） 部分运行日志： [I/FAL] Flash Abstraction Layer (V0.5.99) initialize success. partition name:[user_data] [user_data] [FlashDB][kv][data] (/home/uwen/matter/atbm_4m_matter/src//extern_src/FlashDB-1.1.2/src/fdb_kvdb.c:1912) KVDB size is 32768 bytes.

FDB_WRITE_GRAN 设置了多大？

FDB_WRITE_GRAN 设置了多大？

设置的为1

define FDB_WRITE_GRAN 1

const struct fal_flash_dev atbm_onchip_flash = { .name = "atbm_onchip_flash", .addr = FLASH_USR_DATA_SECTION2_ADDR, .len = FLASH_USR_DATA_SECTION2_LEN, .blk_size = DEVICE_SECTOR_SIZE, .ops = {init, read, write, erase}, .write_gran = 1 };

我感觉还是 Flash 驱动的问题比较大，这块要重点检查一下

好的好的，非常感谢，因为这块被封装起来了，只给了一些上层的接口，有可能是这个原因，我再尝试解决一下，非常非常感谢！
