STM32 WL55JC1 FUOTA

IngSerio · ‎2025-05-23

Good morning,

I have been trying to integrate FUOTA for a few days in my Nuclo STM32 WL55JC1 project.

Starting from the provided example STM32CubeWL_FW_1.3.1 from MXCube, if I try to build in CubeIDE I get the following error:

make[1]: *** No rule to make target ‘C:/Users/Asepa/02 STM/ReD/LoRaWAN_FUOTA/Middlewares/Third_Party/SubGHz_Phy/stm32_radio_driver/radio.c’, needed by ‘Middlewares/SubGHz_Phy/radio.o’. Stop.

make: *** [makefile:70: all] Error 2

Also, on previous posts I read that you would need to build the BFU, the KMS_Blob, the SECoreBin. I found in previous versions some files but even there I could not build.

I would be very interested since I am going into production in the FUOTA speech but I can't integrate it, is there a guide done properly on how to do it? In my project I started with LoRaWan_EndNode_FreeRTOS.

Alternatively, is there an external device that I can easily connect to effuat the upgrade?

Thank you to those who will answer me.

Hello @IngSerio

For the FUOTA on the STM32WL, I think you should have a look at this tutorial from ST and this external Tutorial that should guide you. Also, the AN5554 and AN5544 should also give you more details.

Best Regards.
