Hi team,
Here's an issue from the customer may need your help:
The customer wants to save CPU resources by configuring DMA for SCI receive and SCI/LIN is uesd.
When the DMA source address is configured to scilinREG- RD, the DMA receive data is all zeros. While if using the scireceivebyte feature in SCI to store Rx of sci in data1 and also generate a request request from DMA, place data1 in data, the DMA is able to working properly.
The customer would like to know why can't use sciRd as the source address directly. Could you help check this case? Thanks.
Best Regards,
Cherry
