How can I create the STM32WBA55CGUX_FLASH.ld file?

[YBAYR.1]

I'm using STM32CubeIDE 2.0 and CubeMX 6.16.1. When I create a project in CubeMX, it doesn't create the STM32WBA55CGUX_FLASH.ld file. It creates the makefile when I select it in the Toolchain/IDE section, but then gives an error.

Hello @YBAYR.1 

Thank you for bringing this up!

Could you please check the project directory to confirm if the STM32WBA55CGUX_FLASH.ld file is not present?

The STM32WBA55CGUX_FLASH.ld file doesn't exist initially.

I can create it using CubeMX with toolchain/ide:makefile, but I get an error in the compiler.

[Souhaib MAZHOUD]

CubeMX should add linker file titled "STM32WBA55xx_FLASH.ld" instead of "STM32WBA55CGUX_FLASH.ld".

can you check please?

What do you mean by, "initially" here?

How, exactly, did you get to that point?

Yes, the whole purpose of CubeMX is to create a complete project for you - including source code, linker script, and the IDE Project or makefile.

I did it this way; it gave an error in the first compilation, but it worked in the second compilation.

this is the first compilation

My settings are like this

[YBAYR.1]

first compilation

The first time I press the compile button, it gives an error.

Then, when I press it again, it doesn't give an error.

Your screenshot chops off the end of the line - so we can't see the full message.

Better to copy & paste it as text - see here for instructions.

I'll send the entire line. But what I don't understand is why it gave an error the first time I compiled it, and then suddenly gave zero errors; that's very strange. And it's like this every time I make a change to the project.

Hello @YBAYR.1 

It seems that this error is related to BLE applications, as mentioned in Stm32CubeIDE errata known issue: https://wiki.st.com/stm32mcu/wiki/STM32CubeIDE:STM32CubeIDE_errata_2.0.x#STM32WB0,

as workaround you can use the linker option: -z noexecstack.
