Hi,
Would it be possible to get an explanation of exactly what is the CPLD doing? A flowchart or step-by-step explanations? I realize it's providing the RCW to the processor and controlling the POR. But as one is trying to design a board, one needs to understand exactly what the CPLD code does and how to modify it for or one's specific needs.
Please let me know
Thanks in advance!

Have a great day,
The LS1021A itself does not required for any CPLD. I.e. using CPLD in LS1021A based sytem is not mandatory. I guess you mean some board based on the LS1021A. But I do not see which one. For example the LS1021A-IOT Gateway Reference Design Board has CPLD. Correspondingly QorIQ LS1021A-IOT Gateway Reference Design Board Reference Manual explains the CPLD system controller architecture in chapter 4.
If you need for CPLD code of any NXP reference design board please open a service case. Please see How I could create a Service Request?

Hello Serguei,
Thanks for the answer.
My question was specific to the LS102xA.
I do realize that it is not mandatory to use a CPLD but it helps in setting up the correct RCW. So since this is already done by NXP, I was considering if the NXP Apps engineer, that created the CPLD code, had created a flow chart (or a table) to guide him when he was generating the RTL code. If this was available this gives a head start to duplicate or modify the CPLD code on a customer board. I already downloaded the CPLD code from extranet.
Thanks again for both your answers (ECC and CPLD).
