Function HAL_SRAM_Write_DMA(....) setup

Dear all,

I am trying to use the above function to transfer data from STM32F429 to an external SRAM device but I am not able to see the signals generated.

I can use without ptoblems a similar function (HAL_SRAM_Write_16b(...)).

I am using STM32cubeIDE I have tried to configure a MemToMem DMA but without success.

Does anyone knows If I have to setup first the DMA?

What be the steps to get this function working?

This are the exact functions I use:

HAL_SRAM_Write_16b(&hsram1, (uint32_t*)(SRAM_BANK_ADDR+WRITE_READ_ADDR+2*uwIndex) , aTxBuffer, BUFFER_SIZE);
HAL_SRAM_Write_DMA(&hsram1, (uint32_t*)(SRAM_BANK_ADDR+WRITE_READ_ADDR+2*uwIndex) , (uint32_t*)aTxBuffer, BUFFER_SIZE);

Thanks in advance,

Joaquín.
