NUCLEO-WBA55CG: ISM330DHCX init fails at ISM330DHCX_Set_Mem_Bank with X-NUCLEO-IKS02A1

[kclauah]

Hello,

I have been working with a NUCLEO-WBA55CG board and the X-NUCLEO-IKS02A1 expansion board. When running my initialization code, the program execution jumps to the error handler. Using a debugger, I've pinpointed the failure to the ISM330DHCX_Set_Mem_Bank function. The function returns an error status, which triggers my error handling routine. My initial approach was to replicate the project setup described in DataLogTerminal project . This led directly to the failure at ISM330DHCX_Set_Mem_Bank. I have compared my initialization code against the reference implementation in Board Extension IKS02A1 ISM330DHCX_0_Probe function and they appear to be identical.

My Questions:

• Is there a known compatibility issue for using ISM330DHCX with the NUCLEO-WBA55CG board?
• Could this failure point to a I2C communication problem or a timing issue? How can I fix it?
• Any recommended procedure for initializing I2C or this sensor?

 Here is the code that I added:

/* USER CODE BEGIN Includes */
#include "ism330dhcx.h"
#include "stm32wbaxx_nucleo_bus.h"
/* USER CODE END Includes */

  /* USER CODE BEGIN 2 */
  MX_MEMS_Init();
  /* USER CODE END 2 */

/* USER CODE BEGIN 4 */
static void MX_MEMS_Init(void){
	ISM330DHCX_IO_t io_ctx;
	io_ctx.Address = ISM330DHCX_I2C_BUS;
	io_ctx.BusType = ISM330DHCX_I2C_ADD_H;
	io_ctx.Init = BSP_I2C1_Init;
	io_ctx.DeInit = BSP_I2C1_DeInit;
	io_ctx.ReadReg = BSP_I2C1_ReadReg;
	io_ctx.WriteReg = BSP_I2C1_WriteReg;
	io_ctx.GetTick = BSP_GetTick;
	io_ctx.Delay = HAL_Delay;

	int32_t ret = 0;
        ISM330DHCX_Object_t imu_sensor;
	ret = ISM330DHCX_RegisterBusIO(&imu_sensor, &io_ctx);
	if (ret != ISM330DHCX_OK){
		Error_Handler();
	}
	ret = ISM330DHCX_Set_Mem_Bank(&imu_sensor, ISM330DHCX_USER_BANK);
	if (ret != ISM330DHCX_OK){
		Error_Handler();
	}

	uint8_t id;
	ret = ISM330DHCX_ReadID(&imu_sensor, &id);
	if (ret != ISM330DHCX_OK){
		Error_Handler();
	}
	if (id != ISM330DHCX_ID){
		Error_Handler();
	}

	ISM330DHCX_AxesRaw_t axes_raw;
	ISM330DHCX_Init(&imu_sensor);
	ISM330DHCX_ACC_SetOutputDataRate(&imu_sensor, 26.0f);
	ISM330DHCX_ACC_SetFullScale(&imu_sensor, ISM330DHCX_16g);
	ISM330DHCX_ACC_GetAxesRaw(&imu_sensor, &axes_raw);
	ISM330DHCX_GYRO_SetOutputDataRate(&imu_sensor, 26.0f);
	ISM330DHCX_GYRO_SetFullScale(&imu_sensor, ISM330DHCX_4000dps);
	ISM330DHCX_GYRO_GetAxesRaw(&imu_sensor, &axes_raw);

	ISM330DHCX_ACC_Enable(&imu_sensor);
	ISM330DHCX_GYRO_Enable(&imu_sensor);
}

Steps to Reproduce:

• Create a new STM32 project in STM32CubeIDE.
• In the Board Selector, choose NUCLEO-WBA55CG and initialize the project with default peripheral settings.
• Navigate to "Connectivity" and enable I2C1. Set the SCL and SDA pins to PB1 and PB2 respectively.
• Change I2C speed mode to Fast Mode. Other settings leave unchanged.
• Navigate to "System Core" RCC. and select HSE and LSE to crystal/ceramic resonator
• Navigate to "Computing" and enable CRC.
• Navigate to "Trace and Debug" Debug and select Serial Wire.
• Navigate to "Timers" RTC and activate Clock Source and Calendar
• Navigate to "Middleware" X-CUBE-MEM1 and activate AccGyr ISM330DHCX

Environment:

• STM32CubeIDE: 1.19.0
• STM32Cube MCU Pack for STM32WBA series: 1.7.0
• X-CUBE-MEMS1: 11.3.0
• Windows 10
