使用ali-MQTT和memheap出错

发布于 2019-05-15 15:28:32 浏览：1646 订阅该版

由于ali-mqtt的内存资源太大,我扩展了SRAM.  在正点原子的F4开发板上实现了memheap功能,  把内部的128K和外部的1M SRAM连在一起使用.   出现rt_memheap_free的断言,具体如下:

之前使用mem的时候,没有此问题.

由于这个问题跟踪比较麻烦,  还请哪位高手指点下.

目前我已经确认FSMC的初始化应该没有问题, 我自己也用代码测试过读写,完全正确, 具体初始化代码如下:

void EXT_SRAM_Configuration(void)
{ 
    /* FSMC GPIO configure */
    {
        GPIO_InitTypeDef  GPIO_InitStruct;
        
        __HAL_RCC_GPIOD_CLK_ENABLE();

        __HAL_RCC_GPIOF_CLK_ENABLE();
        __HAL_RCC_GPIOG_CLK_ENABLE();
        __HAL_RCC_FSMC_CLK_ENABLE();
        
        GPIO_InitStruct.Mode = GPIO_MODE_AF_PP;
        GPIO_InitStruct.Pull = GPIO_PULLUP;
        GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_HIGH;
        GPIO_InitStruct.Alternate = GPIO_AF12_FSMC;
        
        GPIO_InitStruct.Pin = GPIO_PIN_0 | GPIO_PIN_1 | GPIO_PIN_4 | GPIO_PIN_5 | GPIO_PIN_8 | GPIO_PIN_9 | GPIO_PIN_10

        HAL_GPIO_Init(GPIOD, &GPIO_InitStruct);

    }
