Seeking solution to download files in BF 531 for production environment

Hello community,

Can you please help me to figure out best solution for firmware downloading in BF 531 processor in production environment?

Due to mishandling and other issues, ICE 1000 emulators gets short circuited with production team. Is there any cost effective solution to update firmware in BF 531 processor?

Can you give me some idea about isolation between debugger and computer, so that it can't get short circuit?
