# Offline Toolchain Cache for RuvLLM ESP32
|

#
|

# Downloads and caches the ESP32 toolchain for air-gapped environments.

# Run this on a machine with internet, then transfer the cache folder.

# Usage:
|
||||
# ./offline-cache.sh create # Create cache
|
||||
# ./offline-cache.sh install # Install from cache
|

# ./offline-cache.sh verify # Verify cache integrity
