Can't build STM32WL FUOTA example with STM32CubeIDE

Question

Good day I am trying to run the Lorawan FUOTA demo on my nucleo-wl55jc1 and havinf trouble. Once i build files in the recommended order and they build successfully, i am getting this issue: struggling to find out what i need to change in order for it to work.  I am using cubeIDE version 1.19.0. Please assist as we plan into going into production very soon on our own PCB board.

Hello @HKhan.4;

To solve the build issue with STM32CubeIDE 1.19.0 version, I recommend you to add this instruction under 1_Image_KMS_Blob/Application/User/kms_blob_example_keys.c file:

__attribute__((weak)) void _close(void){} 
__attribute__((weak)) void _lseek(void){} 
__attribute__((weak)) void _read(void){} 
__attribute__((weak)) void _write(void){}

or you can copy syscalls.c and sysmem.c files from \STM32Cube_FW_WL_V1.3.1\Projects\NUCLEO-WL55JC\Applications\LoRaWAN_FUOTA\1_Image_SECoreBin\STM32CubeIDE\Application\User and paste under STM32Cube_FW_WL_V1.3.1\Projects\NUCLEO-WL55JC\Applications\LoRaWAN_FUOTA\1_Image_KMS_Blob\STM32CubeIDE\Application\User

I hope this help you to solve the build issue.

Thank you.
