stm32f429的nand hal 驱动有bug

HAL_NAND_Write_Page函数要多加一句   *(__IO uint8_t *)((uint32_t)(deviceaddress | ADDR_AREA)) = 0x00U; ，如下
/* Send read page command sequence */
    *(__IO uint8_t *)((uint32_t)(deviceaddress | CMD_AREA)) = NAND_CMD_AREA_A;
   
    *(__IO uint8_t *)((uint32_t)(deviceaddress | ADDR_AREA)) = 0x00U;
    *(__IO uint8_t *)((uint32_t)(deviceaddress | ADDR_AREA)) = 0x00U; //add
    *(__IO uint8_t *)((uint32_t)(deviceaddress | ADDR_AREA)) = ADDR_1ST_CYCLE(addressoffset);
    *(__IO uint8_t *)((uint32_t)(deviceaddress | ADDR_AREA)) = ADDR_2ND_CYCLE(addressoffset);
    *(__IO uint8_t *)((uint32_t)(deviceaddress | ADDR_AREA)) = ADDR_3RD_CYCLE(addressoffset);

HAL_NAND_Read_Page要改三个地方 ，下边有add就是增加语句

    /* Send read page command sequence */
    *(__IO uint8_t *)((uint32_t)(deviceaddress | CMD_AREA)) = NAND_CMD_AREA_A;
   
    *(__IO uint8_t *)((uint32_t)(deviceaddress | ADDR_AREA)) = 0x00U;
    *(__IO uint8_t *)((uint32_t)(deviceaddress | ADDR_AREA)) = 0x00U; // 1  add
    *(__IO uint8_t *)((uint32_t)(deviceaddress | ADDR_AREA)) = ADDR_1ST_CYCLE(addressoffset);
    *(__IO uint8_t *)((uint32_t)(deviceaddress | ADDR_AREA)) = ADDR_2ND_CYCLE(addressoffset);
    *(__IO uint8_t *)((uint32_t)(deviceaddress | ADDR_AREA)) = ADDR_3RD_CYCLE(addressoffset);
 
    /* for 512 and 1 GB devices, 4th cycle is required */
    if(hnand->Info.BlockNbr >= 1024U)
    {
     *(__IO uint8_t *)((uint32_t)(deviceaddress | ADDR_AREA)) = ADDR_4TH_CYCLE(addressoffset);
    }
 
    *(__IO uint8_t *)((uint32_t)(deviceaddress | CMD_AREA))  = NAND_CMD_AREA_TRUE1;

    for(i = 0; i < 10; i++);//2  add
    if(NAND_WaitRB(1))return HAL_BUSY;    //3//add

Re: stm32f429的nand hal 驱动有bug

升级到最新的就不会有bug，兼容性就比较好
