driver for external SRAM chip - IS66WVS4M8ALL/BLL
Hi, I'm trying to add an external memory and i choose that chip because it can communicate with QSPI and there is no need for designing due the chip is SOIC-8 which i found a compatible board for it.
I'm getting issues with the driver writing i'm getting all the time a hard fault or infinite loop. i use chatGPT for the driver writing because i didn't found any written one.
My QUADSPI configuration:
This is the driver:

When i'm getting into HAL_StatusTypeDef QSPI_EnterQPI(QSPI_HandleTypeDef *hqspi) function
i get stuck in this function:
static HAL_StatusTypeDef QSPI_WaitFlagStateUntilTimeout(QSPI_HandleTypeDef *hqspi, uint32_t Flag,
FlagStatus State, uint32_t Tickstart, uint32_t Timeout)
{
/* Wait until flag is in expected state */
while((__HAL_QSPI_GET_FLAG(hqspi, Flag)) != State)
{
/* Check for the Timeout */
if (Timeout != HAL_MAX_DELAY)
{
if(((HAL_GetTick() - Tickstart) > Timeout) || (Timeout == 0U))
{
hqspi->State = HAL_QSPI_STATE_ERROR;
hqspi->ErrorCode |= HAL_QSPI_ERROR_TIMEOUT;
return HAL_ERROR;
}
}
}
return HAL_OK;
} '''
which i don't understand why
Someone can help me?
