Can't build STM32WL FUOTA example with STM32CubeIDE

[HKhan.4]

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.

[HKhan.4]

when I use the script, i get this issue:

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.

Hi

Thank you for this. I was able to complete the build but i am still running into issues.  Please refer to the ticket below:
https://community.st.com/t5/stm32-mcus-wireless/lorawan-fuota/td-p/832920

Please let me know when I can possibly have feedback.

Hello @HKhan.4,

Thank you for updating post.

Glad to know that the initial issue is solved and you are able to build the project without issue. 

For that, please click on Accept as Solution on the reply which solved your issue.

For the second issue, I will share the second post with wireless team expert.

Thank you.
