Hello,
Using a NUCLEO H7S3L8, I'm trying to run a test where, using circular DMA with a linked list, I'm trying to send a buffer in memory over to the SAI for audio playback, using an external DAC. This configuration is based on either other tutorials or the reference manual, but it always throws a User Error flag and calls the DMA's IRQ handler, right after the HAL_DMAEx_List_Start_IT() call (whether done on its own after the necessary configuration, or as part of HAL_SAI_Transmit_DMA()).
Even with some changes, it always yields the same results. The only one that seemed to have any effect was setting the Transfer Event mode to trigger the TC flag for each linked list item, which confirmed that a transfer might have been completed, despite the error flag.
I have also seen GPDMA being configured with circular, using both Standard Request Mode and a Linked List, but haven't gotten any success out of that myself (with even TC flag not being raised).
In case it causes any complications, the board also is configured as a USB Audio device (leftover from previous test, not used currently), and the SAI is configured at 16 bits, at 48 kHz.
Below are images of the configuration:
I'll also leave main.c of the application project, where the only parts of relevant user code have been written.
Any help or advice would be greatly appreciated.
