Placing Entire Program into Linker Output Section

[rnicolls]

Hi,

I'm working with the i.MXRT1176 and using the managed linker scripts to split the Flash Memory into multiple sections. Two of the sections will contain a copy of the entire program (.rodata and .text). I see that I can use MCUXpresso to specify input sections such as data tables, object files or entire source folders and the their corresponding output sections but is there are way to specify the entire program and it's corresponding output section. Is it possible to specify two copies of the program and their corresponding output sections?

Thanks

Hi @rnicolls ,
Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
Actually, I'm not very clear with your question, so can you clarify it again?
Have a great day,

Hi, 

For example, by default the linker command file has a section called Board Flash which is used as the program memory. If I split that section into Board Flash 1 and Board Flash 2, how would I specify Board Flash 2 as the program memory?

Thanks

Hi @rnicolls ,
Thanks for your reply.
1) If I split that section into Board Flash 1 and Board Flash 2, how would I specify Board Flash 2 as the program memory?
-- It's possible to do it, however, Flash 2 should occupy the beginning partition of the FlexSPI's memory address range.
Have a great day,
