Compilation errors on Keil with OpenAmp project generated with CubeMX

[hllelek33]

Hi,

I am new about dual core mcu. I have stm32h745 mcu. 

I am working about inter core comminication, Firstly setting some setting on CubeMx.

When I create project codes, CubeMx creat 2 openamp library for each mcu(m4/m7).

After that I am trying build, and getting error like this.

 Error: L6200E: Symbol OPENAMP_init_ept multiply defined (by openamp_1.o and openamp.o). 

16 times geting similar error like this. 

Why CubeMx create wrong library. 

CubeIde working properly. (create only 1 library set)

Hello,

I tried to start a project with OpenAmp on stm32h745  and didn't face any issue.

Which IDE are you using?

I attached a project created with STM32CubeIDE.

PS: you can inspire from the examples provided in STM32CubeH7 from this link: https://github.com/STMicroelectronics/STM32CubeH7/tree/master/Projects/STM32H747I-EVAL/Applications/OpenAMP

Thanks for replys.

My IDE Keil uVision V5.26.2.0

Hello,

Thank you for the feedback. Is that possible to generate the project with CubeIDE and tell what it happens?

PS: I have errors with KEIL (but are not the same as yours) and IAR  .. (already reported the issue internally on ticket 172397.

What is the CubeMx version you're using?

Hi, 

Thank you. I am waiting for solution. Is there an any notification about solution for me?

[mƎALLEm]

Don't worry, if there will be any news I will let you know ;)

Add-on:

For IAR in the .icf files add:

 

define symbol __OPENAMP_region_start__ = 0x38000400;
define symbol __OPENAMP_region_size__ = 0xB000;
export symbol __OPENAMP_region_start__;
export symbol __OPENAMP_region_size__; 

 

PS: 0x38000400 and 0xB000 are only examples. You can change them if you want. Just be sure they are not interleaving with other used memory regions.

It is worked.
