[ STM32F7 QuadSPI ] HAL_QSPI_Command_IT can not Jump to QUADSPI_IRQHandler

HPham.1590

Hello, I'm using QuadSPI to read/write to external flash on STM32F746NG.

I used this example from ST and it's working correctly: https://github.com/STMicroelectronics/STM32CubeF7/tree/master/Projects/STM32746G-Discovery/Examples/QSPI/QSPI_ReadWrite_IT

But when I add this function to my project, with RTOS mode, this function make my program stuck.

I tried to run 2 task paralel and both of them is not working, but when I remove task which include QuadSPI, it's still working correctly:

  osThreadDef(MQTTThread, MQTTTask, osPriorityNormal, 0, 1024);
  MQTTTaskHandHandle = osThreadCreate(osThread(MQTTThread), client);
  osThreadDef(UpdateThread, SyncTask, osPriorityNormal, 0, 256);
  UpdateTaskHandle = osThreadCreate(osThread(UpdateThread), client);

In debug mode, when I jump over HAL_QSPI_Command_IT function, pointer jump to TIM6_DAC_IRQHandler instead of QUADSPI_IRQHandler although I set QUADSPI_IRQn with highest priority:

HAL_NVIC_SetPriority(QUADSPI_IRQn, 0x00, 0);
  HAL_NVIC_EnableIRQ(QUADSPI_IRQn);

Bellow is my code which running on my QuadSPI task. Anyone can tell me what's wrong in my program? Many thanks.

I have same problem. after execution's of HAL_QSPI_Command_IT(&hqspi,&sCommand) it did not jump to void HAL_QSPI_CmdCpltCallback(QSPI_HandleTypeDef *hqspi)

finally i did not check for call back procced for receive or transmit then the program working according to the command send by HAL_QSPI_Command_IT :grinning_face:

please give me any another sustainable solution:downcast_face_with_sweat:

Thank god finally solved my problem.....

when exicute HAL_QSPI_Command_IT(&hqspi,&sCommand) in data transition reception instructions the callback is not called because transition and reception part also come after HAL_QSPI_Command_IT(&hqspi,&sCommand) instruction .after successful reception we got void HAL_QSPI_RxCpltCallback(QSPI_HandleTypeDef *hqspi) or

void HAL_QSPI_TxCpltCallback(QSPI_HandleTypeDef *hqspi) callback.... but not void HAL_QSPI_CmdCpltCallback(QSPI_HandleTypeDef *hqspi)

void HAL_QSPI_RxCpltCallback(QSPI_HandleTypeDef *hqspi)

{

qspi_reception = END;

HAL_GPIO_TogglePin(USR_LED_GPIO_Port,USR_LED_Pin);

}

void HAL_QSPI_ErrorCallback(QSPI_HandleTypeDef *hqspi)

{

while(1)

{

HAL_Delay(300);

HAL_GPIO_TogglePin(USR_LED_GPIO_Port,USR_LED_Pin);

}

}

void HAL_QSPI_TxCpltCallback(QSPI_HandleTypeDef *hqspi)

{

qspi_transmission = END;

HAL_GPIO_TogglePin(USR_LED_GPIO_Port,USR_LED_Pin);

}

for example

sCommand.AddressSize    = QSPI_ADDRESS_24_BITS;

sCommand.AlternateByteMode = QSPI_ALTERNATE_BYTES_NONE;

sCommand.AlternateBytesSize=QSPI_ALTERNATE_BYTES_8_BITS;

sCommand.Instruction = CMD_Read_Status_Register_1;

sCommand.AddressMode = QSPI_ADDRESS_NONE;

sCommand.Address   = 0;

sCommand.DataMode  = QSPI_DATA_1_LINE;

sCommand.DummyCycles = 0;

sCommand.NbData=1;

BUSY100: qspi_cmd_transmission = START;

if (HAL_QSPI_Command_IT(&hqspi,&sCommand)!= HAL_OK)

{

Error_Handler();

}

qspi_reception = START;

if(HAL_QSPI_Receive_DMA(&hqspi,&status_register_1)!=HAL_OK)

{

Error_Handler();

}

else

{

while(qspi_reception != END);

}

but in chip erase like instuction it is only a command no data txn or rxn

so it will call

void HAL_QSPI_CmdCpltCallback(QSPI_HandleTypeDef *hqspi)

{

qspi_cmd_transmission = END;

}

eg:

sCommand.AddressSize    = QSPI_ADDRESS_24_BITS;

sCommand.AlternateByteMode = QSPI_ALTERNATE_BYTES_NONE;

sCommand.AlternateBytesSize=QSPI_ALTERNATE_BYTES_8_BITS;

sCommand.Instruction = CMD_64KB_Block_Erase;

sCommand.AddressMode = QSPI_ADDRESS_1_LINE;

sCommand.Address   = 0X00;

sCommand.DataMode  = QSPI_DATA_NONE;

sCommand.DummyCycles = 0;

sCommand.NbData=0;

qspi_cmd_transmission = START;

if (HAL_QSPI_Command_IT(&hqspi,&sCommand)!= HAL_OK)

{

Error_Handler();

}

else

{

while(qspi_cmd_transmission != END);

}
