Legacy BSP Kconfig files map BSP_DIR/RTT_DIR symbols to BSP_ROOT/RTT_ROOT environment variables while sourcing paths through $RTT_DIR. Env initialized only part of this mapping, leaving Kconfiglib unable to resolve some configurations.

  • BSP environment

    • Export BSP_ROOT alongside BSP_DIR.

  • RT-Thread environment

    • Populate both RTT_ROOT and RTT_DIR from the detected RT-Thread root before Kconfig parsing.
os.environ['BSP_ROOT'] = bsp_root
os.environ['BSP_DIR'] = bsp_root

os.environ['RTT_ROOT'] = rtt_root
os.environ['RTT_DIR'] = rtt_root
