ARM : Get memory region start address from map file in c.

Şükrü Arslan

Hello,
I want to reserve memory region for specific data.
So I edit the scatter file and I add following line to the scatter file.

; *************************************************************
; *** Scatter-Loading Description File generated by uVision ***
; *************************************************************

LR_IROM1 0x08000000 0x00040000 { ; load region size_region ER_IROM1 0x08000000 0x00040000 { ; load address = execution address *.o (RESET, +First) *(InRoot$$Sections) .ANY (+RO) } RW_IRAM1 0x20000000 0x00040000 { ; RW data .ANY (+RW +ZI) } RW_IRAM2 +0 EMPTY 0x10000 // I ADD THIS SECTION ! {

}
}

My first question is, Is this way is true for reserve memory region ?
second question is, independent from first question, How can I access this memory region (RW_IRAM2) from c code ?

Thanks for your answers !
Best Regards.
