Manufacturing system and firmware burning method

A manufacturing system, comprising:

• a target device, comprising:
• a storage circuit, for storing a setting code and to-be-burned firmware;
• a target circuit, for determining whether firmware of the target circuit satisfies a condition, and enables a control signal when the firmware does not satisfy the condition;
• and
• a peripheral controller, connected to the storage circuit via a first communication link, being switched to a disabled state in response to the enable control signal;
• and
• a test fixture, comprising:
• a first node and a second node, respectively coupled to the storage circuit and the target circuit;
• and
• a switch circuit, connected across the first and second nodes, being turned on in response to the enable control signal to form a second communication link between the target circuit and the storage circuit via the first and second nodes;
• wherein, after providing the control signal, the target circuit further accesses the storage circuit via the second communication link and updates the firmware according to the to-be-burned firmware.
