Two OSPI usage in STM32U599

[Epamuk]

Hello, 

Is it possible to use two OSPI with below configuration.  I can make this configuration in cubeMx but whiel debugging ospi1 is not working after ospi2 initialize.

Hello @Epamuk ;

First of all thank you for sharing this behavior in the community.

Could you please look at this issue Solved: OCTOSPI: HAL_OSPIM_Config() - STMicroelectronics Community. I think you are experiencing the same issue.

To solve the issue could you please try to modify these code lines in octospi.c file

  sOspiManagerCfg.ClkPort = 1;
  sOspiManagerCfg.NCSPort = 1;
  sOspiManagerCfg.IOLowPort = HAL_OSPIM_IOPORT_1_LOW;
  if (HAL_OSPIM_Config(&hospi1, &sOspiManagerCfg, HAL_OSPI_TIMEOUT_DEFAULT_VALUE) != HAL_OK)
  {
    Error_Handler();
  }

  sOspiManagerCfg.ClkPort = 2;
  sOspiManagerCfg.NCSPort = 2;
  sOspiManagerCfg.IOLowPort = HAL_OSPIM_IOPORT_1_HIGH;
  if (HAL_OSPIM_Config(&hospi2, &sOspiManagerCfg, HAL_OSPI_TIMEOUT_DEFAULT_VALUE) != HAL_OK)
  {
    Error_Handler();
  }

  sOspiManagerCfg.ClkPort = 1;
  sOspiManagerCfg.NCSPort = 1;
  sOspiManagerCfg.IOLowPort = HAL_OSPIM_IOPORT_1_LOW;
  sOspiManagerCfg.IOHighPort = HAL_OSPIM_IOPORT_1_HIGH;
  sOspiManagerCfg.DQSPort = 1;
  if (HAL_OSPIM_Config(&hospi1, &sOspiManagerCfg, HAL_OSPI_TIMEOUT_DEFAULT_VALUE) != HAL_OK)
  {
    Error_Handler();
  }

  sOspiManagerCfg.ClkPort = 2;
  sOspiManagerCfg.NCSPort = 2;
  sOspiManagerCfg.IOLowPort = HAL_OSPIM_IOPORT_1_LOW;
  sOspiManagerCfg.IOHighPort = HAL_OSPIM_IOPORT_1_HIGH;
  sOspiManagerCfg.DQSPort = 2;
  if (HAL_OSPIM_Config(&hospi2, &sOspiManagerCfg, HAL_OSPI_TIMEOUT_DEFAULT_VALUE) != HAL_OK)
  {
    Error_Handler();
  }

Please let me know if the issue is solved or not?

Thank you.

Hello, my code was like (cubeMX created that)

  sOspiManagerCfg.ClkPort = 1;
  sOspiManagerCfg.NCSPort = 1;
  sOspiManagerCfg.IOLowPort = HAL_OSPIM_IOPORT_1_LOW;
  if (HAL_OSPIM_Config(&hospi1, &sOspiManagerCfg, HAL_OSPI_TIMEOUT_DEFAULT_VALUE) != HAL_OK)
  {
    Error_Handler();
  }

  sOspiManagerCfg.ClkPort = 2;
  sOspiManagerCfg.NCSPort = 2;
  sOspiManagerCfg.IOLowPort = HAL_OSPIM_IOPORT_1_HIGH;
  if (HAL_OSPIM_Config(&hospi2, &sOspiManagerCfg, HAL_OSPI_TIMEOUT_DEFAULT_VALUE) != HAL_OK)
  {
    Error_Handler();
  }

I added only  sOspiManagerCfg.IOHighPort = HAL_OSPIM_IOPORT_1_HIGH; to OSPI1 init like below

  sOspiManagerCfg.ClkPort = 1;
  sOspiManagerCfg.NCSPort = 1;
  sOspiManagerCfg.IOLowPort = HAL_OSPIM_IOPORT_1_LOW;
  sOspiManagerCfg.IOHighPort = HAL_OSPIM_IOPORT_1_HIGH;
  if (HAL_OSPIM_Config(&hospi1, &sOspiManagerCfg, HAL_OSPI_TIMEOUT_DEFAULT_VALUE) != HAL_OK)
  {
    Error_Handler();
  }

 and it works fine .  

Thanks
