EasyFlash无法正常使用的问题

xiaodingding opened this issue 5 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

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

Answer 1 · 2020-05-12T09:28:17.000Z

看着像内存被写穿了，初始化相关代码贴一下

Answer 2 · 2020-05-12T09:28:52.000Z

是不是因为内存不够的原因

Answer 3 · 2020-05-12T09:35:11.000Z

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;

}

以下是改为mutex的日志：

Answer 6 · 2020-05-12T11:08:43.000Z

增大下初始化线程的堆栈试试

Answer 7 · 2020-05-13T01:38:24.000Z

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。

Answer 8 · 2020-05-17T01:49:51.000Z

你用的是 EEPROM 吗？

Answer 9 · 2020-05-18T23:55:15.000Z

嗯，是的，是外置的eeprom

Answer 10 · 2020-05-20T01:06:24.000Z

你的 ef_cfg.h 贴一些，确保写粒度有配置正确
