Hi,

There is two build options like RAM and FLASH in example empty projects at driverlib folder.

What is the real difference between them? Why do I need to build it RAM instead of FLASH or vice verse.

All the code will be loaded to FLASH at the end, right?

I'm planning to use DCL. Can I still build my project as flash or it must be RAM?

Gokhan,

Please refer to this e2e link. Flash expert has explained the difference.

Santosh,

Thank you for answers. I can follow it up.

I also need answers of above questions that are related to basics.

Best regards,

Gokhan,

You are correct; eventually all the initialized sections should be mapped to the flash. However, during initial code development, developers generally tend to map their code (except when they want to benchmark the code for performance evaluation) to RAM since it takes very less time to load to RAM when compared to that of flash.

Thanks and regards,
Vamsi
