HAL_OSPIM_Config incorrectly deactivates another instance

Configuration method incorrectly deactivates the other instance in case any of the following signals are turned off for both instances: DQSPort = 0(disabled) IOLowPort = HAL_OSPIM_IOPORT_NONE IOHighPort = HAL_OSPIM_IOPORT_NONE

Hello @raitraak-rrk

Would you please give us more details about how you got this issue? Did you observed it at runtime ? if so, could you please share the code you have used to reproduce the problem. With regards,

[raitraak-rrk]

Hi,

Sharing the full code is not trivial. Pseudo code for same value of DQSPort:

OSPI_HandleTypeDef ospiHandle1; OSPIM_CfgTypeDef ospimCfg1 { 1U, 0U, 1U, HAL_OSPIM_IOPORT_1_LOW,HAL_OSPIM_IOPORT_1_HIGH }; HAL_OSPIM_Config(&ospiHandle1, &ospimCfg1, HAL_OSPI_TIMEOUT_DEFAULT_VALUE); OSPI_HandleTypeDef ospiHandle2; OSPIM_CfgTypeDef ospimCfg2{ 2U, 0U, 2U, HAL_OSPIM_IOPORT_2_LOW,HAL_OSPIM_IOPORT_NONE }; HAL_OSPIM_Config(&ospiHandle2, &ospimCfg2, HAL_OSPI_TIMEOUT_DEFAULT_VALUE);

Second call to HAL_OSPIM_Config disables the first instance. Should be pretty obvious. Please let me know if you need more info.

Hello @raitraak-rrk,

If you may, I need to know that the lines of code that you shared are as they are, consecutive and there is no other instruction between the 2 calls of HAL_OSPIM_Config, like HAL_OSPI_Init.
