B-WL5M-SUBG1 got warning on lorawan app on repo

Question

I tried demo project from repo/STM32Cube_FW_WL_V1.3.0/Projects/B-WL5M-SUBG1/Applications/Lorawan/LoRaWAN_End_Node. i change the Region to my region on Lorawan minddleware setting on CubeMX.

After "debug as" STM32 C/C++ application and got warning "Projects using Sigfox, LoRaWAN or SubGHz_Phy may require a customized linker file." what does it means ?

What does it means? and after debug as , got many error.

I follow this video tutor from https://www.youtube.com/watch?v=yL-7YqUFl0k seems works for Nucleo-WL55.

Anyone can help ?

Hello @flyrobot

projects using Sigfox, LoRaWAN, or SubGHz_Phy often require a customized linker file. This is because these projects typically involve specific memory layout requirements, such as placing certain sections of code or data in specific memory regions. This should not be the source of the issues you shared on the debug verbose file.

Those problems came from:

A problem on the definition of Prob pins in the radio_conf.h (can be configured on the SUBGHZ_PHY Middleware on the Platform Settings tab after enabling the Probes Lines in Platform Settings.
A problem of defining some variables (LORAWAN_APP_DATA_BUFFER_MAX_SIZE, FLASH_IF_OK, EventType, TX_ON_EVENT, CFG_SEQ_Task_LoRaSendOnTxTimerOrButtonEvent, LORAWAN_SWITCH_CLASS_PORT, and LORAWAN_USER_APP_PORT). in the Files lora_app.h/c, flash_if.h and utilities_def.h.

I suggest you to refer to the end node LoRaWAN example on the STM32CubeWL to understand how to solve this.

Best Regards.
