Hi everyone!

I need a help about SPI communication.

Our HW is IMX8MM and linux environ. 

echo_1234.png

Above diagram of ECSPI2 output stream by LA. and I used a echo command in shell like as "echo "1234" > /dev/spidev1.0"

 

In here, why does it separate SPI bit-stream like above? 

please tell me, how to prevent this separation? I need a seamless transmission.

please,...
