# Run on the Proxmox host (as root) when rpiboot fails with "No 'bootcode' files found".
# Cause: mass-storage-gadget64/bootfiles.bin is a broken symlink (-> ../firmware/bootfiles.bin).
# This script removes the symlink and extracts bootcode4.bin from the installed rpiboot binary.
#
# On host: bash fix-gadget-bootcode-on-host.sh
