I was wondering if it is possible to have SPIBlockingTransfer, SPINonBlockingTransfer (Interrupt Based) and SPISdmaTransfer all 3 working at the same time? 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?
