This document proposes a remote access system for hardware testing boards in an FST lab that would allow students to remotely access and test boards through a secure web service without transferring source code. The system would use HTTPS and VPN protocols to securely transfer only binary files. User data on the boards would be erased after each session to protect privacy and ensure a clean environment for subsequent tests. A demo of remote access is shown using an online STM32 simulator. The system could also enable automatic testing by allowing students to upload test programs (TPs), run them on the remote boards, and download results.

• It is a web service that provides remote access to
development/Boards Farm
• protected by standard SLL algorithms and HTTPS Protocol
• User doesn’t have to transfer any source code to the server,
only binaries are transferred
• All data on target boards cleaned up after sessions end (flash
chips are erased, default firmware is flashed, ...)
