Linker warning message

[pgo]

Dear All,

I'm trying to align an object at a 512 byte boundary using the following  (fragment) in the linker file:

  .usbram :
  {
    . = ALIGN (512);
    *(.bdts)
    . = ALIGN (0x4);
  } >> userram
   

This appears to work as I expected it to but produces the following warning message:

All segments to userram have to begin at address aligned to 512 Please add ".=ALIGN(512);" before every "} >> userram"

Is this message correct or spurious as I hope?

Using CW v10.1 on Win32 with a MCF51JM64 target device if thats relevent.

 bye

Hello

I would need the whole .lcf file to check what is going on here.

I cannot analyze or reproduce anything with the fragment you have provided.

I have the same issue.

 .main_application_bss :
    {
        __START_SBSS = .;
        *(.sbss)
        *(SCOMMON)
        __END_SBSS = .;
        __START_BSS = .;
        m52259unc_regabi.a(.bss)
        mqx_regabi.a(.bss)
        rtcs_regabi.a(.bss)
  crc.c(.bss)
  unc500_gpio5.c(.bss)
  Flash_Upgrade_Task.c(.bss)
        *(.bss)
        *(COMMON)
  . = ALIGN(0x20);
        __END_BSS = .;
    } >> ram
  .kernel_data : AT(ADDR(.main_application_bss) + SIZEOF(.main_application_bss) )
    {
        ___KERNEL_DATA_START = ALIGN(0x20);
    }
   
    .end_of_kernel_data :
    {
        ___KERNEL_DATA_END = .;
    } > end_of_kd
    .boot

I dont see any issues with the load and everything seems to line up according to plan.

I get the warning message with the value of the ALIGN used in the .bss segment.

If I omit the ALIGN in the kernel data I dont get the message.
