Unknown chip id! 0x497 error despite being the correct one
Hi,
I am new to this community and working with the STM32 family. I am doing some experiments using the following settings:
- OS- Mac OS 12.5.1
- Board: Nucleo-WL55JC1
- stlink v3
- st-flash 1.7.0
I am trying to deploy a simple code (blinking LED) on the board using only the terminal.
I tried to code on the board before using the cubeIDE and works fine.
I used the make command and I have the .elf file, but when I try:
% st-flash write code_application_CM4.elf 0x08000000
st-flash 1.7.0

2023-10-09T14:36:43 WARN common.c: unknown chip id! 0x497
Failed to connect to target
I also tried:
% st-util --verbose=99

I checked stlink/inc/stm32.h and it seems that the ID is correct:
STM32_CHIPID_WLE = 0x497,
So I don't understand why is unknown or what I can do to fix it.
Thanks for your help; Cristina.
