Hi,

I am currently using below RCW configuration.

#PBL preamble and RCW header

aa55aa55 01ee0100

0610000A 00000000 00000000 00000000

60000000 00407909 60044A00 21046000

00000000 00000000 00000000 00418700

20004D04 0884B300 00000000 00000000

Requirement :

Bits (128-135) needs to set to either 0x50 or 0x60 based on the condition of one GPIO pin.

Can this configuration be modified from my application?

If yes, please describe on the possible method of doing it.

if no, please suggest the alternative method to meet the above requirement.

Regards,

Sukruth

This is not possible - only RCW field determines the SerDes Protocol.

It is possible to use NOR Flash as RCW source and divide it to several banks (at least two) by means of a hardware circuit or CPLD. The banks could contain different RCWs and could be switched by an external signal.
