I need technical support for the following:

Would like to be able to set the start address of a program at 0x08002000 on a STM32F103RBT6, load the vector table and the program code set next to this address. Can't find proper directive to do that thing.

I can’t change the code start address in the PROCESSOR menu using ride7. Is there any ways to do that

Thanks a lot

Stéph

Hi Stéphane,

the best recommended way is to create a customized linker script (you can use as a basis the autogenerated scripts and include them into one standalone file) and modify the FLASH line in the MEMORY section that looks like this:

MEMORY
{
  RAM (xrw) : ORIGIN = 0x20000000, LENGTH = 20K
  FLASH (rx) : ORIGIN = 0x8000000, LENGTH = 32K
  FLASHB1 (rx) : ORIGIN = 0x00000000, LENGTH = 0
  EXTMEMB0 (rx) : ORIGIN = 0x00000000, LENGTH = 0
  EXTMEMB1 (rx) : ORIGIN = 0x00000000, LENGTH = 0
  EXTMEMB2 (rx) : ORIGIN = 0x00000000, LENGTH = 0
  EXTMEMB3 (rx) : ORIGIN = 0x00000000, LENGTH = 0
}

regards
