Hello,

I'm using LS1021a micro and when I transfer data from QorIQ, in out signals I get the attached picture (yellow = clk, green = cs)

There is a large gap between bytes and it is not always the same.

I would like to reduce this gap to the minimum possible.

 

 

Additional data:

- SPIDEV library.

- C and Python code

 - SPI mode 3.

- Clock Tested: 1MHz, 4MHz, 8MHz...

- Kernel 4.14.78.

- Yocto

 

Thank you in advance.

 

PD: Attached picture and source code used for test.
