Dear community.

Our customer has question below.

About the SPI interface of  i.MX6Dual ,
Is it possible to toggle the burst transfer in Master mode every time like 512 bytes, 496 bytes, 512 bytes, 496 bytes, and so on?

FIFO read / write uses DMA.

Hi Takashi

I am afraid not as BURST_LENGTH register ECSPIx_CONREG

should be configured properly every time for particular burst size.

Best regards
