STM32 + ST-LINK: Second memory section not programmed to flash

Mike S over 11 years ago

I'm using a STM32F103C8 + ST-LINK.

I have created a second memory section in the scatter file:

LR_IROM1 0x08000000 0x00010000  {    ; load region size_region

  ER_IROM1 0x08000000 0x00005000   {  ; load address = execution address
  *.o  (RESET, +First)
  ;*(InRoot$$Sections)
   .ANY (+RO)
  }
  MY_SECT 0x08005000  0x00000400 {
    main.o
  }
  RW_IRAM1 0x20000000 0x00005000  {  ; RW data
   .ANY (+RW +ZI)
  }
}

Everything compiles. It looks like the programmer loads to flash. However, when I execute code in the debugger, all memory in that new section is 0xFF.

Seems like maybe it is an option for the ST-LINK debugger, but I can't find anything that seems to help.

Any suggestions?

Thank you!
