FileNotFoundError: [Errno 2] No such file or directory: 'E:\quectel\proj\rtthread\env-windows\tools\bin\..\..\packages\packages/peripherals/hal-sdk/stm32/stm32f4_hal_driver\package.json'`

Start by reproducing pkgs --update in the reported STM32 BSP and inspect the package-update path in env/cmds/cmd_package/cmd_package_update.py, especially install_package, along with env/package.py parsing. Confirm whether the reported package path and package.json lookup are handled correctly; done means the command completes without the shown FileNotFoundError.
