EasyFlash无法正常使用的问题

Open xiaodingding opened this issue 4 years ago • 12 comments

1.芯片：STM32L151CBT6。 2.报错函数： void ef_port_env_lock(void) { rt_sem_take(&env_cache_lock, RT_WAITING_FOREVER); } 3.分区名称 “ef” 4.fal接口 const struct fal_flash_dev eeprom0 = { "eeprom0", 0, 16*1024, 64, {init, read, write, erase} }; 5.分区表 #define FAL_PART_TABLE
{
{FAL_PART_MAGIC_WROD, "ef", "eeprom0", 0, 12 * 1024, 0}, } 6.fal组件正常，能够正常读写外置flash的数据，但是EasyFlash，一直不能正常工作。 7.EasyFlash日志 0> at24cxx_init for fal init successful 0> [D/FAL] (fal_flash_init:61) Flash device | eeprom0 | addr: 0x00000000 | len: 0x00004000 | blk_size: 0x00000040 |initialized finish. 0> [I/FAL] ==================== FAL partition table ==================== 0> [I/FAL] | name | flash_dev | offset | length | 0> [I/FAL] ------------------------------------------------------------- 0> [I/FAL] | ef | eeprom0 | 0x00000000 | 0x00003000 | 0> [I/FAL] ============================================================= 0> [I/FAL] RT-Thread Flash Abstraction Layer (V0.2.0) initialize success. 0> msh >spi init successful, find spi10 device! 0> result:3, hu_data:1f4 0> [E/DBG] Failed write PWR_REG, not support power manager 0> [E/DBG] Failed write PWR_REG, not support power manager 0> init message queue failed. 0> [Flash] (packages\EasyFlash-v4.1.0\src\ef_env.c:1818) ENV start address is 0x00000000, size is 8192 bytes. 0> at24cxx_page_read offset:0 size:16 0> [Flash] Warning: Sector header check failed.

8.注释掉ef_port_env_lock和ef_port_env_unlock的内容，还是无法正常运行。

看着像内存被写穿了，初始化相关代码贴一下

May 12 '20 09:05 armink

是不是因为内存不够的原因

May 12 '20 09:05 xiaodingding

EfErrCode ef_port_init(ef_env const **default_env, size_t *default_env_size) { EfErrCode result = EF_NO_ERR;

*default_env = default_env_set;
*default_env_size = sizeof(default_env_set) / sizeof(default_env_set[0]);

// rt_sem_init(&env_cache_lock, "env lock", 1, RT_IPC_FLAG_PRIO); 刚注释的

env_cache_mutex = rt_mutex_create("emutex", RT_IPC_FLAG_FIFO);
if(env_cache_mutex == RT_NULL)
{
    rt_kprintf("create easyflash dynamic mutex failed.\n");
    return -1;
}

part = fal_partition_find(FAL_EF_PART_NAME);
EF_ASSERT(part);

return result;

}

增大下初始化线程的堆栈试试

May 12 '20 11:05 armink

目前已经将main线程的堆栈改为4096了，之前的空间大小为1024,现在能看到提示操作成功，但是重启之后，它还是会重新去操作一遍flash。

你用的是 EEPROM 吗？

May 17 '20 01:05 armink

嗯，是的，是外置的eeprom

May 18 '20 23:05 xiaodingding

你的 ef_cfg.h 贴一些，确保写粒度有配置正确
