Hello,

         In errata sheet of imx6ul,  ERR009606 eCSPI: In master mode, burst lengths of 32n + 1 will transmit

incorrect data, this issue is mentioned.  As I understood, there is problem in ecSPI when burst lenght is configured as 32n+ 1 ( where n= 0,1,2,3 ...).

We are using the SPI in master mode with max14830 as slave, so I am looking to check this issue with reproduce. How i can reproduce this issue ?

In workaround it mentioned that, dont use the burst lenght of 32n+ 1.

In the linux driver, where exactly need to configure the burst lenght ?

 

 

Regards,

Surendra
