Project not picking up RAM section from linker file

[TomC1]

I am working with a dual core STM32H755 and attempting to create a shared memory location for the two cores to access. I am attempting to do this by modifying the linker script.  I have added the following lines to the M7 core linker script, in the SECTIONS block:

/* Shared Memory section for inter core comms */
.sharedRAMsection 0x30040000 :
{
    .= ALIGN(4);
    KEEP(*(.sharedRAMsection))
    . = ALIGN(4);
} > RAM_D2

Then in one of my .c files, I have declared the following global variable:

RegisterMap_t __attribute__((section(".sharedRAMsection"))) g_RegisterMap;

However, when I debug I can see the address of this variable has been assigned to memory location 0x24000064, as seen in the watch window:

I am using visual studio and visual GDB, and I am debugging with 2 separate VS instances for the two cores.

Is there something else that I need to do in order to get this variable into the correct memory location?

Thanks

How is RAM_D2 define in the memory section?

Use the .MAP or objdump to see how the symbol is defined

KEEP(*(.sharedRAMsection))

KEEP(*(.sharedRAMsection*)) /* check if it needs to pull suffix variants ie .sharedRAMsection.data */

RAM_D2 is defined as starting at 0x30000000 and having a size of 288K, which I think has it running up to 0x30048000.

/* Memories definition */
MEMORY
{
  RAM_D1 (xrw)   : ORIGIN = 0x24000000, LENGTH =  512K
  FLASH   (rx)   : ORIGIN = 0x08000000, LENGTH = 1024K    /* Memory is divided. Actual start is 0x8000000 and actual length is 2048K */
  DTCMRAM (xrw)  : ORIGIN = 0x20000000, LENGTH = 128K
  RAM_D2 (xrw)   : ORIGIN = 0x30000000, LENGTH = 288K
  RAM_D3 (xrw)   : ORIGIN = 0x38000000, LENGTH = 64K
  ITCMRAM (xrw)  : ORIGIN = 0x00000000, LENGTH = 64K 
}

Adding the wildcard to sharedRAMsection has no effect.

doesn't the attribute go after the variable name?
