STM32H7S3L8 PSSI with DMA

[Faisal129]

Hello everyone, 

I am trying to use the PSSI peripheral with DMA on my nucleo-H7S3L8, I am new to this GPDMA so at first i tried using the standard request mode and i got it working but it only receives once and stops do i need to manually enable it again? i also tried to put a counter in the HAL_PSSI_RxCpltCallback which did not increment at all. 

I also tried using the linked list mode and followed this tutorial:
How to configure the linked list mode in STM32Cube... - STMicroelectronics Community 
but it does not work at all. 

any clue or advice please? thank you all.

Hello @Faisal129 and welcome to the Community;

I advise you to start with available examples in STM32CubeH7RS, may help you.

- PSSI_Master_ComDMA

- PSSI_Slave_ComDMA

- PSSI_Transmit_DMA

- PSSI_Master_Single_ComDMA

- PSSI_Slave_Single_ComDMA

Thank you.

Dear Kaouthar, 

I already looked through the examples and tried to modified it work for my project, I need to use the PSSI to receive continuous data and fill two buffers that why I wanted to use linked list DMA. unfoundedly this does not work with me if you can help I would appreciate it. 

best regards,
