Guidance Required for Porting STSW-IMG053 to X-NUCLEO-53L9A1 on STM32N6570-DK Using I3C

Hello ST Team,

Good morning!

I am currently working on integrating the VL53L9 sensor with the STM32N6570-DK development board. I have successfully obtained the STSW-IMG053 software package, which is designed for the STEVAL-VL53L9 evaluation board using the MIPI CSI interface.

However, my target hardware configuration is different. My objective is to use the following setup:

  • Software Package: STSW-IMG053
  • Host Board: STM32N6570-DK
  • Sensor Board: X-NUCLEO-53L9A1
  • Communication Interface: I3C

I would like to port the STSW-IMG053 software package to support the X-NUCLEO-53L9A1 evaluation board while retaining the STM32N6570-DK as the host platform.

I would appreciate your guidance on the following points:

  1. Is there an official procedure or application note describing how to port STSW-IMG053 from the STEVAL-VL53L9 (MIPI CSI) platform to the X-NUCLEO-53L9A1 (I3C) platform?
  2. Are there any reference projects, example applications, or software packages available for the STM32N6570-DK with the X-NUCLEO-53L9A1 using the I3C interface?
  3. Which software modules are hardware-specific and need to be modified during the porting process (for example, BSP, platform layer, sensor interface, or initialization sequence)?
  4. Are there any recommended practices or documentation for replacing the MIPI CSI communication layer with the I3C interface while preserving the existing VL53L9 application layer?
  5. Are there any known limitations, compatibility considerations, or dependencies that should be taken into account when using the X-NUCLEO-53L9A1 with the STM32N6570-DK?

Any documentation, porting guidelines, or reference implementations would be extremely helpful.

Thank you in advance for your time and support.

Best regards,

Jitendra

Hi:

As far as I know, L9 with STM32N6570-DK platform that supports I3C driver is developing currently. But if you still want to use I3C, you can refer to L9 with STM32H5 platform driver. Here is the download link: X-CUBE-53L9A1 | Product - STMicroelectronics

Best regards,
