Error compiling startup_ARMCA7.c

[SteMMo33]

Hi all,
I installed the last release: CmsisPackPlugIn2.10.0.zip
I configured for my ST32MP135 board a simple blink code that uses ARMA/ as device and RTOS.
So I selected the following modules:

• CORE
• RTOS2 / Keil RTX5
• IRQ controller
• OS Tick API
• startup

When I run the build, after some succesful operation, I have the following error:

Any idea?

This does not ring a bell with me. Is this the first time you are trying this, or did this work correctly with previous versions of the plug-in?
I have to admit that I am puzzled by the fact that you are writing that your application is targeting "ST32MP135", however the selected device is a generic "ARMCA7" device. I do not expect this code to run on an STM32MP135 this way.

I do not see a CMSIS-Pack for STM32MP135 and you should probably contact STMicroelectronics about this.

I would recommend using STM32CubeMX for creating bare metal projects in combination with the STM32CubeIDE.

Thanks a lot Joachim,
I'm doing a research on development tools for STM32MP devices.
I selected ARMCA7 precisely because I couldn't find the correct and most precise target.
So You confirm me that the MP135 target is not supported.

Hi @SteMMo33, Did you try to compile in regular ARM mode instead of THUMB?

Then, it looks like you are working with fairly old code based on CMSIS 5.6.0. With recent CMSIS 6 we moved the device support to https://github.com/ARM-software/Cortex_DFP/blob/main/Device/ARMCA7/Source/startup_ARMCA7.c

I'd recommend to update to latest code first. Next, you might need to tweak the startup code yourself because generic Cortex-A7 startup code does not consider device specific requirements for your ST32MP device.

Hi @JonatanAntoni ,
yes the CMSIS is version 5.5.1 but it is proposed by the tool as :

[JonatanAntoni]

Don't get confused by pack vs component version. In your case its CMSIS 5.6.0 which ships RTX5 5.5.1. The latest versions available are CMSIS 6.1.0, CMSIS-RTX 5.9.0, and Cortex_DFP 1.1.0. With the major version jump to CMSIS 6 we splittet off RTX5 and device support into their own packs to reduce confusion and increase maintainability.

Open the CMSIS Pack perspective and update/install the new packs. Then the new component versions should show up in this RTE Configuration dialog.
