APM32F407对第2扇区执行擦写操作，首次通电写入数据，数据数量16KB。每次这4个地址数据都不对，下面是错误信息，存储一个二维数组，每组2字。
- cvf enc err [url=home.php?mod=space&uid=72445]@[/url] [1536][0]:: REQ=80A86B9E :: ROM=C9077731
- cvf enc err @ [1536][1]:: REQ=80A86B9E :: ROM=CCD61B08

- cvf enc err @ [1537][1]:: REQ=0D00A6F0 :: ROM=8658FBA2
代码如下：
- void cvf_handle(void)

- int group;
- HAL_StatusTypeDef hal_st;
- cvf_check_alloc();
-
- // enc opt
- cvf_enc_rom_addr_make(0, 0);
- FLASH_Unlock(); // 解锁flash

- FLASH_Erase_Sector(FLASH_SECTOR_2, FLASH_VOLTAGE_RANGE_3);
- for (group = 0; group < CFV_CODE_LEN / 8; group++)
- {
- cvf_enc_gen(group);
- cvf_enc_rom_addr_make(group, 0);
- bsp_flash_write(cvf.addr + 0, cvf.out[0]);
- bsp_flash_write(cvf.addr + 4, cvf.out[1]);
- }
- cvf_free();
- FLASH_Lock();
- }
- int bsp_flash_write(uint32_t addr, uint32_t dat)
- {
- int cnt = 3;
- int err = 1;
- if (dat != UINT32_MAX)

- }
- else
