Import ExternalLoader on STM32CubeIDE error: multiple definition

[WB71]

I want to create my own external loader for STM32U585. So I start with importing IS61WV51216BLL_STM3210E-EVAL (TrueStudio) to STM32CubeIDE. Tis works in principle, but when linking the project I get the error:

update.win32_2.0.0.202105311346\tools\arm-none-eabi\bin\ld.exe: Loader/Dev_Inf.o:(.rodata+0x0): multiple definition of `StorageInfo'; ./Loader/Dev_Inf.o:(.rodata+0x0): first defined here

When I comment the line " KEEP(Loader/Dev_Inf.o ( .rodata ))" in stm32_flash.ld file everything compiles fine, but header with storage info is missing in elf file (*.stldr)

You need KEEP as there's no internal reference to the structure.

​

The Linkers complaining you've defined it TWICE, or more, figure out why that's happening, for example you've defined it in a .H file and included that in multiple places. Don't define/allocate things in Include files...​

The same thing happened to me. The project was working fine with IDE 1.6.0, but after updating it to 1.8.0 it does not work anymore. I am still figuring it out why.

Hello, I have had the same problem, working with 1.5.0, but no more working with 1.8.0.

Have you found something to make this work again?

Thanks,

Marco

Yes, I use this linker script.

But unfortunately external loaders only work with ST-LINK, not with USB bootloader.

So now I write my own bootloader.

Guys, dont forget to uncheck those before generating code; for removing static declaration from the external call functions. Those for example, refer to attached picture.
