Position Independent Code - Linker Error

Hello there

I'm trying to compile and link position independent code using the --apcs=/ropi compile option (C/C++: Read-Only Position Independent). Since I'm using --scatter I can't make use of the linker option "Make RO Sections Position Independent. Instead I mark the RO execution region in my scatter file with the PI option (as mentioned in this post: www.keil.com/.../).

It compiles just fine, but I get the L6248E Linker Error mainly because of the startup file. I understand that the assembler can't generate position independent code. I tried to write the startup code in C so that the compiler takes care of the position independency, unfortunately without success.

It seems like the DCD directive is causing the linker error. Does anyone have a suggestion or solution to my problem? Any help is appreciated.

Im using a STM32F100 Controller with Keil uVision 4.5 Standard Version (Armcc, ArmLink V4.1.0.894)

Here is my scatter file:

LR_IROM1 0x08000000 0x00010000  {    ; load region size_region
  ER_IROM1 0x08000000 PI 0x00010000  {  ; load address = execution address
   *.o (RESET, +First)
   *(InRoot$$Sections)
   .ANY (+RO)
  }
  RW_IRAM1 0x20000000 0x00002000  {  ; RW data
   .ANY (+RW +ZI)
  }
}

and my Startup File (vector table):
