Question
CubeIDE generate Too Big BIN file for STM32WL
Hi
We re trying to compile LoRaWAN_END_Node project from STM32WL Cube library. CubeIDE generate 402 MB bin File. Can someone from STteam look into this.
MCU STM32WLE5CC
Mac Verion 1.0.3
WL 1.3.1

** Abstract : Linker script for STM32WL55xC Device
** 256Kbytes FLASH
** 64Kbytes RAM
**
** Set heap size, stack size and stack location according
** to application requirements.
**
** Set memory bank area and size if external memory is used.
**
** Target : STMicroelectronics STM32
