Restart from SRAM after Bootloader with problems

Hi guys,

i managed to flash my stm32f107vc via the internal bootloader, but i have problems to get the program running after it.
When I reset the MCU the PC is somewhere at the beginning of SRAM i think (0x20000000).
I found out, that if I set the PC to 0x8003000 manually, i can let the sw run and everything including interrupts works fine.
Can someone help me how to manage to jump from 0x20000000 to 0x8003000 after reset?

I am using a linkerfile as seen below:
LR_IROM1 0x08003000 0x00080000-0x3000
   ER_IROM1 0x08003000 0x00080000-0x3000
      * (RESET, +First)
      .ANY (+RO)

   IRAM 0x20000000 0xD800 ; 55296 Byte (10K also 10 Pages sind dahinter noch Platz)
      .ANY2 (+RW +ZI)


before configuring the NVIC i call:
NVIC_SetVectorTable(NVIC_VectTab_FLASH, 0x3000);

thanks for your support guys!
