CubeMX + NUCLEO-L053R8 + X-CUBE-MEMS1 can't be built

[Mario Simunic]

Using CubeMX v5.0 and FW_L0_v1.11.0 I'm generating new project from scratch.

Project has initialized (using HAL) UART2, I2C1 (on alternate pins PB8, PB9), GPIOs, EXTIs and clock. UART2, I2C1 and EXTI interrupts are enabled and IRQ handlers generated by the CubeMX.

On top of that there is X-CUBE-MEMS1 v5.2.1 with IKS01A2 extension and Application IKS01A2-DataLogTerminal. Project is generated for board NUCLEO-L053R8.

Just generated project couldn't be build. There is an error inside stm32l0xx_it.c, in function `USART2_IRQHandler()` error: "Undefined reference to huart2".

Same problem if this project is built for MDK-ARM v5.

CubeMX project file is attached. It's easy to regenerate the project.

I've tried to manually add #include or something in a hope that huart2 would become visible, but this BSP+MEMS1 Application seems like overcomplicated non-modular intertwined firmware. It's too hard to understand.

Please, can someone help me about this, just to make first build.

If it is a single undefined in another source file surely just defining it as an extern would suffice, unless it is a static in main.c

[Mario Simunic]

This works, but now I have problem with the Hard Fault. I'm debugging without IKS01A2 connected.

FW executes until the point when in need to initialize MX_Cube_MEMS1:

MX_X_CUBE_MEMS1_Init(void) --> MX_IKS01A2_DataLogTerminal_Init() --> IKS01A2_MOTION_SENSOR_GetCapabilities(i, &MotionCapabilities[i]) -->

int32_t IKS01A2_MOTION_SENSOR_GetCapabilities(uint32_t Instance, IKS01A2_MOTION_SENSOR_Capabilities_t *Capabilities)
{
  int32_t ret;
 
  if (Instance >= IKS01A2_MOTION_INSTANCES_NBR)
  {
    ret = BSP_ERROR_WRONG_PARAM;
  }
  else if (MotionDrv[Instance]->GetCapabilities(MotionCompObj[Instance], Capabilities) != BSP_ERROR_NONE)
  {
    ret = BSP_ERROR_UNKNOWN_COMPONENT;
  }
  else
  {
    ret = BSP_ERROR_NONE;
  }
 
  return ret;
}

The line `else if (MotionDrv[Instance]->GetCapabilities(MotionCompObj[Instance], Capabilities) != BSP_ERROR_NONE)` produces Hard Fault exception.

I have X-NUCLEO-IKS01A1, so there is a task awaiting :) - to port IKS01A1 code to this project and see if Hard Fault will be produced then.

Dear Mario,

I suggest you to

https://www.st.com/content/st_com/en/products/embedded-software/mcus-embedded-software/stm32-embedded-software/stm32cube-expansion-packages/x-cube-mems1.html

and the go to folder

STMicroelectronics.X-CUBE-MEMS1.5.2.1\Projects\STM32L053R8-Nucleo\Examples\IKS01A2\DataLogTerminal

The DataLogTerminal.ioc should have the right settings to solve your problem.

@parata.carlo​ for any follow-up.

Best regards,

Luca

Hi Mario,

you can try the IoC that I posted above (split in 2 pieces). It works fine on my side with CubeMX v5.0.0, MEMS pack v5.2.1 and CubeL0 v1.11.0. Obviously, in order to test it you need a Nucleo-L053R8 and a X-NUCLEO-IKS01A2.

Best Regards,

Carlo

[Mario Simunic]

I don't have X-NUCLEO-IKS01A2.

It seems that calling the function

MotionDrv[Instance]->GetCapabilities(MotionCompObj[Instance], Capabilities) 

with parameters Instance = 0, Capabilities = NULL produces HardFault. - Because? - I'm not sure.

As much as I'm figured this out, There is no IKS01A2 connected so Capabilities stays NULL - it's updated to non of possible capability.

[parata.carlo]

Hi Mario,

actually, if you try to debug the code, you should find that all the IKS01A2_***_Init functions fail when they check the WHOAMI id of the several MEMS components (if you do not plug the IKS01A2, you will obviously get an error for any I2C transaction). So, all the Init functions in your case will exit with an error code and they are not able to assign the driver APIs (like the GetCapabilities) to the instances of the MEMS sensors. This is the reason why you get an HardFault when you call the GetCapabilities. In the sample application the error management was neglected for simplicity, so the real program flow should stop after the first error in the IKS01A2_***_Init. Anyway, in my opinion, it does not make sense to test this code if you do not have the IKS01A2. I hope that this explains the behavior that you see.

Best Regards,

Carlo
