i.MX6SD eCSPI MISO when slave mode.

Question asked by Satoshi Shimoda on Feb 17, 2015

Hi community,

 

Our partner have a question about i.MX6SDL eCSPI.

Acctually, partner check the behavior of MISO when i.MX6SDL is slave mode.

Then, "zero" was output from MISO when BURST_LENGTH = 0x1F if TXFIFO is empty, but some data is output when BUST_LENGTH = 0x0F or 0x07.

It seems that the output data is not last data.

 

Then, I found similar post in TX Issue on i.MX6 ECSPI (Slave), but it seems that it have not resolved yet.

So would you let me know what is occured and how to avoid this issue?

 

 

 

Best Regards,
