How to fix static assertion failed: "Retargetable locking must be enabled" and warnings in newlib

[VineetaNarkhede-eaton]

Hi,
I am migrating to zephyr 3.2.0 from zephyr 3.1.0. Compiling custom watchdog code on ESP32.
Getting assert failure and warnings in newlib
Error:

I tried to update esp32 toolchain through west espressif install and update but these commands are not working in zephyr 3.2.0. getting below error,
usage: west espressif [-h] [-b BAUD] [-p PORT] [-e ELF] {monitor} west espressif: error: argument command: invalid choice: 'install' (choose from 'monitor')
It's not working even after running west update successfully.
I ran install.bat from "\zephyr-v3.2.0\modules\hal\espressif", but running into other errors.

west espressif install and update working partially in zephyr 3.1.0, it is installing only openocd-esp32, I somehow managed to get other tools as shown below

Environment :
OS: Windows
Toolchain Zephyr SDK 0.15.2 , espressif : esp-2020r3-8.4.0 (C:\Users<username>.espressif\tools\zephyr)
Zephyr version: 3.2.0

Please suggest the solution for above error and warnings

• Please format your warnings. It's hard to read
• Can we see the code or can you provide a MWE?
