STM32H7S3H6 Application Crashes During XSPI1 Initialization

[Danhe]

I’m encountering an issue with XSPI1 in my application. I boot the application via XSPI2 in an LRUN configuration, and this part works perfectly. However, within the application, I need to use XSPI1 to write data to a different flash.

During MX_XSPI1_Init(), the code crashes at this line:

if (HAL_XSPIM_Config(&hxspi1, &sXspiManagerCfg, HAL_XSPI_TIMEOUT_DEFAULT_VALUE) != HAL_OK)
{
Error_Handler();
}

I traced the crash to the exact line:

IOM_cfg[0].IOPort = pCfg->IOPort;

The initialization code for XSPI1 was generated using CubeMX. Interestingly, if I initialize XSPI1 in the boot project, everything works fine.

I’ve already spent a week trying to solve this issue, but so far nothing has worked.

I would really appreciate  suggestions to help solve my problem.
