How to modify the default ITCM/DTCM/OCRAM memory allocations for i.MX RT1064

Hello,

 

   Our team is using the i.MX RT1064 microprocessor to develop an application that will likely exceed the 128KB ITCM memory size allocated by default. We have read through AN12077 and informed ourselves about the static and runtime configuration options using the Flexram, and at this point in the development we would like to understand more about how to partition the memory banks using the fuse settings.

 

What is the recommended method for modifying the default static RAM configuration? From what I understand, writing to the fuse settings during manufacturing time is best? Otherwise, are there any other methods that do not require this extra step of modifying fuse settings?

 

Thank you in advance,

Alin
