Unhelpful message: L6235E: More than one section matches selector - cannot all be FIRST/LAST.

Andy Neil 

mbed/TARGET_NUCLEO_L152RE/TOOLCHAIN_ARM_MICRO/stm32l152re.sct(34):
error: L6235E: More than one section matches selector - cannot all be FIRST/LAST.

So how about telling me which sections they are?!

I have exported an mbed project from the online compiler, and simply opened it in uVision-4 and tried to build it.
I have made no changes at all.

:-(

This is the stm32l152re.sct file - error line highlighted:

; STM32L152RE: 512KB FLASH + 80KB SRAM
LR_IROM1 0x08000000 0x80000  {    ; load region size_region

  ER_IROM1 0x08000000 0x80000  {  ; load address = execution address
   *.o (RESET, +First)
   *(InRoot$$Sections)
   .ANY (+RO)
  }

  ; 73 vectors = 292 bytes (0x124) to be reserved in RAM
  RW_IRAM1 (0x20000000+0x124) (0x14000-0x124)  {  ; RW data
   .ANY (+RW +ZI)
  }

}

Any hints on how to find the offending Sections?

    Not sure exactly how best to search.

    But it complains that more than one source file contains "AREA RESET".

    For example a *.s file with a line:

                    AREA    RESET, DATA, READONLY

    What *.o files will match if you do grep for RESET?

    Well, just deleting the Scatter file gives me a load of "Multiple Definition" errors:

    .\build\Nucleo_printf.axf: Error: L6200E: Symbol __Vectors_Size multiply defined (by startup_stm32l152xe.o and startup_stm32l1xx_hd.o).

    So there we have it: startup_stm32l152xe.o and startup_stm32l1xx_hd.o are, presumably, the ones causing the duplicates.

    So why couldn't the L6235E message have told me this??

    Grrrr

    Thanks - you must have posted that while I was typing my reply!

    Unfortunately the current version of UVision tells me that the scatter file is missing or empty (I tried both).
