Problems solved by technology

R&D testers sometimes bind the pins of the programmer into the JTAG interface in a specific order to refresh the CPLD conveniently and quickly, which will cause the situation that the JTAG interface and the pins of the programmer do not have a one-to-one correspondence.
However, when the current board is designed, there are usually no protection measures against this situation. Once the GND line of the writer is connected to the PWR of the JTAG interface by mistake, it will cause a short circuit in the writer, resulting in damage, causing property loss, and even affecting the progress of development and testing
[0005] Therefore, how to avoid the damage caused by the wrong insertion of the programmer due to the difference in the order of the JTAG interface pins of different boards or other situations has important research significance in the field of programmer programming

Abstract

The invention discloses a burner safety protection method and system and computer equipment, and relates to the technical field of computers. The method comprises the following steps: acquiring the level of a power pin of a joint test behavior organization interface; if the level of the power pin of the joint test behavior organization interface is a high level, connecting a power supply circuit of the joint test behavior organization interface; and if the level of the power pin of the joint test behavior organization interface is a low level, cutting off a power supply circuit of the joint test behavior organization interface. According to the invention, on and off of the power supply circuit of the joint test behavior organization interface can be controlled based on the level of the power supply pin of the joint test behavior organization interface, so that the situation of short-circuit damage of the burner caused by misplug of the burner due to different sequences of JTAG interface pins on different board cards is avoided; the property loss is effectively avoided, and the development and test efficiency is improved.
