STM32: ST-Link tries to flash RAM region - gcc

Question

I'm working with a STM32F407VG with 128kB of normal RAM and 64kB of Core Coupled Memory (CCM). I'm using a GCC toolchain (SW4STM32).
In my linker script I configured the CCM like this:
MEMORY
{
FLASH (rx) : ORIGIN = 0x08000000, LENGTH = 1024K
RAM (xrw) : ORIGIN = 0x20000000, LENGTH = 128K
CCM (xrw) : ORIGIN = 0x10000000, LENGTH = 64K
}
SECTIONS
{
...
.ccram :
{
*(.ccram)
*(.ccram*)
} >CCM
...
When I put any variables into the .ccram section I get an ELF file which seems to tell ST-Link that it has to flash the memory at 0x10000000. This fails, of course, and tells me
"Warn : no flash bank found for address 10000000".
When I create a HEX file from the ELF file, I find a block of zeros at 0x10000000. When I delete this block from the HEX file, I can flash the HEX file successfully (with ST-Link Utility) and my code runs perfectly on the target.
So how do I tell the linker (or whoever) that the CCM region shall not be marked as FLASH?

Answer 1

I think you need to replace >CCM with >CCM AT> FLASH
This should tell it to get the init values from flash

Answer 2

I got the solution:
Add "(NOLOAD)" to the deklaration of the section:
.ccram (NOLOAD):
{
*(.ccram)
*(.ccram*)
} >CCM
