I am using an i.MX8. Would I continuously have to Enable and Disable SPI SDMA constantly to achieve this? I would like to have some operations to happen over DMA while others to happen directly. I am not sure if this is even possible. Has anyone tried this?</P></BODY></HTML> Thu, 04 Apr 2019 21:18:49 GMT https://community.nxp.com/t5/i-MX-Processors/Simultaneously-use-SPI-Blocking-NonBlocking-and-SDMA-Transfer/m-p/881017#M133531 vaparikh 2019-04-04T21:18:49Z Re: Simultaneously use SPI Blocking/NonBlocking and SDMA Transfer https://community.nxp.com/t5/i-MX-Processors/Simultaneously-use-SPI-Blocking-NonBlocking-and-SDMA-Transfer/m-p/881018#M133532 <HTML><HEAD></HEAD><BODY><P>May I ask which product are you using? which BSP are you using?</P></BODY></HTML> Tue, 09 Apr 2019 07:31:53 GMT https://community.nxp.com/t5/i-MX-Processors/Simultaneously-use-SPI-Blocking-NonBlocking-and-SDMA-Transfer/m-p/881018#M133532 jimmychan 2019-04-09T07:31:53Z Re: Simultaneously use SPI Blocking/NonBlocking and SDMA Transfer https://community.nxp.com/t5/i-MX-Processors/Simultaneously-use-SPI-Blocking-NonBlocking-and-SDMA-Transfer/m-p/881019#M133533 <HTML><HEAD></HEAD><BODY><P>I am trying to get this to work on an IMX8MQ on the Cortex M4 side.
