How to solve this hardfault concerning memory access restriction?

The code goes to

HAL_I2S_Receive_DMA at __HAL_UNLOCK(hi2s);

and

void HAL_DMA_IRQHandler(DMA_HandleTypeDef *hdma)

{

 uint32_t tmpisr;

 __IO uint32_t count = 0;

 uint32_t timeout = SystemCoreClock / 9600;

 /* calculate DMA base and stream number */

 DMA_Base_Registers *regs = (DMA_Base_Registers *)hdma->StreamBaseAddress;

 tmpisr = regs->ISR; => hardfault_handler

Failed to execute MI command:

-data-evaluate-expression "((DMA_Base_Registers *)hdma->StreamBaseAddress)->ISR"

Error message from debugger back end:

Cannot access memory at address 0xf8960000

Failed to execute MI command:

-data-evaluate-expression "((DMA_Base_Registers *)hdma->StreamBaseAddress)->Reserved0"

What did I miss here?
