How to ensure that a specific section of RAM is reserved and nothing else is written to it, using the linker command file?

How can I ensure that a specific section of RAM is reserved and nothing else is written to it, using the linker command file? Don't get me wrong I will be reading and writing the section from my application. But I don't want any kind of over writing to happen which can cause data loss at run time. This is for C28386x

Hi Gokulnath,

Do you want an entire block reserved? In that case you could just not sue that block in the section mapping. For example, if you want to reserve LS0RAM, do not use LS0RAM in the sectionName : > MemoryBlock instructions under SECTIONS.

Hi,

What if I want to reserve a range of address in LS0RAM.

Should I specify the range in memory directive and then not use it under the sections? like

Memory

{

CUSTOM_RANGE : origin = 0x0010 , Length=0x00FF

}

Hi Gokulnath,

Yes, that will make sure that the memory is not allocated for any sections.
