STM32CubeIDE 1.15.0: elf has a LOAD segment with RWX permissions

Hi @Imen.D  , @Khouloud ZEMMELI ,

After updating the STM32CubeIDE to version 1.15.0 (today) I am observing below warning.

The LD file has not changed. It has RAM and MRAM RWX

C:/ST/STM32CubeIDE_1.15.0/STM32CubeIDE/plugins/com.st.stm32cube.ide.mcu.externaltools.gnu-tools-for-stm32.12.3.rel1.win32_1.0.100.202403111256/tools/bin/../lib/gcc/arm-none-eabi/12.3.1/../../../../arm-none-eabi/bin/ld.exe: warning: xxx.elf has a LOAD segment with RWX permissions

Memory sections in LD file:

MEMORY
{
ITCMRAM (xrw) : ORIGIN = 0x00000000, LENGTH = 64K
FLASH (rx) : ORIGIN = 0x08000000, LENGTH = 2048K
DTCMRAM (xrw) : ORIGIN = 0x20000000, LENGTH = 128K
RAM_D1 (xrw) : ORIGIN = 0x24000000, LENGTH = 512K
RAM_D2 (xrw) : ORIGIN = 0x30000000, LENGTH = 288K
RAM_D3 (xrw) : ORIGIN = 0x38000000, LENGTH = 64K
MRAM (xrw) : ORIGIN = 0x60000000, LENGTH = 1024K
}

Please help resolve the concern.

Regards,

Rajeev

Hi @RajeevAroraCrcEvans,

i have added an example.

You have copied every part, thats not correct.

Delete this part:

  .ARM.extab   : {
    . = ALIGN(4);
    *(.ARM.extab* .gnu.linkonce.armextab.*)
    . = ALIGN(4);
  } >FLASH

 Just use this:

.ARM.extab (READONLY)   : {
    . = ALIGN(4);
    *(.ARM.extab* .gnu.linkonce.armextab.*)
    . = ALIGN(4);
  } >FLASH

 And also at the other parts.

Best regards,

Jens

Hi Rajeev,

I had the same problem, this one is easy.

You have to edit your Linker-File. But you have to make sure that your configuration uses the correct file.

There must be an additional (READONLY) at these positions:

  • .ARM.extab (READONLY) :
  • .ARM (READONLY) :
  • .preinit_array (READONLY) :
  • .init_array (READONLY) :
  • .fini_array (READONLY) :

Best regards,

Jens

Hi @JensH 

Are you informing that I need to update:

 

  .ARM.extab   : {
    . = ALIGN(4);
    *(.ARM.extab* .gnu.linkonce.armextab.*)
    . = ALIGN(4);
  } >FLASH

 

to

 

  .ARM.extab (READONLY)   : {
    . = ALIGN(4);
    *(.ARM.extab* .gnu.linkonce.armextab.*)
    . = ALIGN(4);
  } >FLASH
  .ARM.extab   : {
    . = ALIGN(4);
    *(.ARM.extab* .gnu.linkonce.armextab.*)
    . = ALIGN(4);
  } >FLASH

 

Is it possible for you to share a file with these settings?

Regards,

Rajeev

Hi @RajeevAroraCrcEvans ,

no it's not that complicated.

Just add "(READONLY)". For example:

.ARM.extab (READONLY) :
  {
    *(.ARM.extab* .gnu.linkonce.armextab.*)
  } >FLASH

.ARM (READONLY) :
  {
    __exidx_start = .;
    *(.ARM.exidx*)
    __exidx_end = .;
  } >FLASH

Best regards,

Jens

Hi @JensH 

I still observe same error. That is why I requested for an example.

  /* Constant data goes into FLASH */
  .rodata :
  {
    . = ALIGN(4);
    *(.rodata)         /* .rodata sections (constants, strings, etc.) */
    *(.rodata*)        /* .rodata* sections (constants, strings, etc.) */
    . = ALIGN(4);
  } >FLASH

  .ARM.extab   : {
    . = ALIGN(4);
    *(.ARM.extab* .gnu.linkonce.armextab.*)
    . = ALIGN(4);
  } >FLASH

  .ARM.extab (READONLY)   : {
    . = ALIGN(4);
    *(.ARM.extab* .gnu.linkonce.armextab.*)
    . = ALIGN(4);
  } >FLASH

  .ARM : {
    . = ALIGN(4);

  } >FLASH

  .ARM (READONLY): {
    . = ALIGN(4);
    __exidx_start = .;
    *(.ARM.exidx*)
    __exidx_end = .;
    . = ALIGN(4);
  } >FLASH

  .preinit_array     :
  {
    . = ALIGN(4);
    PROVIDE_HIDDEN (__preinit_array_start = .);
    KEEP (*(.preinit_array*))
    PROVIDE_HIDDEN (__preinit_array_end = .);
    . = ALIGN(4);
  } >FLASH

  .preinit_array     (READONLY):
  {
    . = ALIGN(4);
    PROVIDE_HIDDEN (__preinit_array_start = .);
    KEEP (*(.preinit_array*))
    PROVIDE_HIDDEN (__preinit_array_end = .);
    . = ALIGN(4);
  } >FLASH

  .init_array :
  {
    . = ALIGN(4);
    PROVIDE_HIDDEN (__init_array_start = .);
    KEEP (*(SORT(.init_array.*)))
    KEEP (*(.init_array*))
    PROVIDE_HIDDEN (__init_array_end = .);
    . = ALIGN(4);
  } >FLASH

  .init_array (READONLY):

    . = ALIGN(4);
    PROVIDE_HIDDEN (__init_array_start = .);
    KEEP (*(SORT(.init_array.*)))
    KEEP (*(.init_array*))
    PROVIDE_HIDDEN (__init_array_end = .);
    . = ALIGN(4);
  } >FLASH

  .fini_array :

    PROVIDE_HIDDEN (__fini_array_start = .);
    KEEP (*(SORT(.fini_array.*)))
    KEEP (*(.fini_array*))
    PROVIDE_HIDDEN (__fini_array_end = .);

Thanks @JensH 

Can confirm same happened to my project today after update to 1.15
Linker skript previously WAS NOT edited by me so the problem might be related to update itself

I had the same problem. I followed your suggestion.

It's working.

Thanks,

Constantin

Hi, @JensH: with the same problem after the update, I followed your solution and worked for me as well.

Could you shared with us why this problem appears after the update and how you came up with this concrete patch?

Just willing to learn from this.

Thanks,

Bruno
