Hello All,

I have two questions:

1) For Cortex r4f core, whether the addresses in the map file are LOAD/RUN addresses and Whether PRE/POST eclipsing ??

2) What is exactly done by the boot loader in cortex r4f ROM and how could affect its behavior of allocating sections in the memories TCMA & TCMB ??

It is urgent.

Thanks in advance.

Hi,

the load/run addresses are defined in the linker.cmd file.

There are many e2e threads in the compiler forum regarding this.

You can allocate sections in TCMA/B

thank you

Hello Cesar,

The first inquiry is about the addresses in the map file not the linker. Are they load/run, pre/post eclipsing ?

Thanks an advance.

All addresses in the map file are executable addresses. Eclipsing means that ROM and TCMA share the same addresses and after boot runs, the ROM is "eclipsed" so that the user program only sees RAM.
